# Webclaw
|
||||
|
||||
Rust workspace: CLI + MCP server for web content extraction into LLM-optimized formats.
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
webclaw/
|
||||
crates/
|
||||
webclaw-core/ # Pure extraction engine. WASM-safe. Zero network deps.
|
||||
# + ExtractionOptions (include/exclude CSS selectors)
|
||||
# + diff engine (change tracking)
|
||||
# + brand extraction (DOM/CSS analysis)
|
||||
webclaw-fetch/ # HTTP client via primp. Crawler. Sitemap discovery. Batch ops.
|
||||
# + proxy pool rotation (per-request)
|
||||
# + PDF content-type detection
|
||||
# + document parsing (DOCX, XLSX, CSV)
|
||||
webclaw-llm/ # LLM provider chain (Ollama -> OpenAI -> Anthropic)
|
||||
# + JSON schema extraction, prompt extraction, summarization
|
||||
webclaw-pdf/ # PDF text extraction via pdf-extract
|
||||
webclaw-mcp/ # MCP server (Model Context Protocol) for AI agents
|
||||
webclaw-cli/ # CLI binary
|
||||
```
|
||||
|
||||
Two binaries: `webclaw` (CLI), `webclaw-mcp` (MCP server).
|
||||
|
||||
### Core Modules (`webclaw-core`)
|
||||
- `extractor.rs` — Readability-style scoring: text density, semantic tags, link density penalty
|
||||
- `noise.rs` — Shared noise filter: tags, ARIA roles, class/ID patterns. Tailwind-safe.
|
||||
- `data_island.rs` — JSON data island extraction for React SPAs, Next.js, Contentful CMS
|
||||
- `markdown.rs` — HTML to markdown with URL resolution, asset collection
|
||||
- `llm.rs` — 9-step LLM optimization pipeline (image strip, emphasis strip, link dedup, stat merge, whitespace collapse)
|
||||
- `domain.rs` — Domain detection from URL patterns + DOM heuristics
|
||||
- `metadata.rs` — OG, Twitter Card, standard meta tag extraction
|
||||
- `types.rs` — Core data structures (ExtractionResult, Metadata, Content)
|
||||
- `filter.rs` — CSS selector include/exclude filtering (ExtractionOptions)
|
||||
- `diff.rs` — Content change tracking engine (snapshot diffing)
|
||||
- `brand.rs` — Brand identity extraction from DOM structure and CSS
|
||||
|
||||
### Fetch Modules (`webclaw-fetch`)
|
||||
- `client.rs` — FetchClient with primp TLS impersonation
|
||||
- `browser.rs` — Browser profiles: Chrome (142/136/133/131), Firefox (144/135/133/128)
|
||||
- `crawler.rs` — BFS same-origin crawler with configurable depth/concurrency/delay
|
||||
- `sitemap.rs` — Sitemap discovery and parsing (sitemap.xml, robots.txt)
|
||||
- `batch.rs` — Multi-URL concurrent extraction
|
||||
- `proxy.rs` — Proxy pool with per-request rotation
|
||||
- `document.rs` — Document parsing: DOCX, XLSX, CSV auto-detection and extraction
|
||||
- `search.rs` — Web search via Serper.dev with parallel result scraping
|
||||
|
||||
### LLM Modules (`webclaw-llm`)
|
||||
- Provider chain: Ollama (local-first) -> OpenAI -> Anthropic
|
||||
- JSON schema extraction, prompt-based extraction, summarization
|
||||
|
||||
### PDF Modules (`webclaw-pdf`)
|
||||
- PDF text extraction via pdf-extract crate
|
||||
|
||||
### MCP Server (`webclaw-mcp`)
|
||||
- Model Context Protocol server over stdio transport
|
||||
- 8 tools: scrape, crawl, map, batch, extract, summarize, diff, brand
|
||||
- Works with Claude Desktop, Claude Code, and any MCP client
|
||||
- Uses `rmcp` crate (official Rust MCP SDK)
|
||||
|
||||
## Hard Rules
|
||||
|
||||
- **Core has ZERO network dependencies** — takes `&str` HTML, returns structured output. Keep it WASM-compatible.
|
||||
- **primp requires `[patch.crates-io]`** for patched rustls/h2 forks at workspace level.
|
||||
- **RUSTFLAGS are set in `.cargo/config.toml`** — no need to pass manually.
|
||||
- **webclaw-llm uses plain reqwest** (NOT primp-patched). LLM APIs don't need TLS fingerprinting.
|
||||
- **qwen3 thinking tags** (`<think>`) are stripped at both provider and consumer levels.
|
||||
|
||||
## Build & Test
|
||||
|
||||
```bash
|
||||
cargo build --release # Both binaries
|
||||
cargo test --workspace # All tests
|
||||
cargo test -p webclaw-core # Core only
|
||||
cargo test -p webclaw-llm # LLM only
|
||||
```
|
||||
|
||||
## CLI
|
||||
|
||||
```bash
|
||||
# Basic extraction
|
||||
webclaw https://example.com
|
||||
webclaw https://example.com --format llm
|
||||
|
||||
# Content filtering
|
||||
webclaw https://example.com --include "article" --exclude "nav,footer"
|
||||
webclaw https://example.com --only-main-content
|
||||
|
||||
# Batch + proxy rotation
|
||||
webclaw url1 url2 url3 --proxy-file proxies.txt
|
||||
webclaw --urls-file urls.txt --concurrency 10
|
||||
|
||||
# Sitemap discovery
|
||||
webclaw https://docs.example.com --map
|
||||
|
||||
# Crawling (with sitemap seeding)
|
||||
webclaw https://docs.example.com --crawl --depth 2 --max-pages 50 --sitemap
|
||||
|
||||
# Change tracking
|
||||
webclaw https://example.com -f json > snap.json
|
||||
webclaw https://example.com --diff-with snap.json
|
||||
|
||||
# Brand extraction
|
||||
webclaw https://example.com --brand
|
||||
|
||||
# LLM features (Ollama local-first)
|
||||
webclaw https://example.com --summarize
|
||||
webclaw https://example.com --extract-prompt "Get all pricing tiers"
|
||||
webclaw https://example.com --extract-json '{"type":"object","properties":{"title":{"type":"string"}}}'
|
||||
|
||||
# PDF (auto-detected via Content-Type)
|
||||
webclaw https://example.com/report.pdf
|
||||
|
||||
# Browser impersonation: chrome (default), firefox, random
|
||||
webclaw https://example.com --browser firefox
|
||||
|
||||
# Local file / stdin
|
||||
webclaw --file page.html
|
||||
cat page.html | webclaw --stdin
|
||||
```
|
||||
|
||||
## Key Thresholds
|
||||
|
||||
- Scoring minimum: 50 chars text length
|
||||
- Semantic bonus: +50 for `<article>`/`<main>`, +25 for content class/ID
|
||||
- Link density: >50% = 0.1x score, >30% = 0.5x
|
||||
- Data island fallback triggers when DOM word count < 30
|
||||
- Eyebrow text max: 80 chars
|
||||
|
||||
## MCP Setup
|
||||
|
||||
Add to Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json`):
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"webclaw": {
|
||||
"command": "/path/to/webclaw-mcp"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Skills
|
||||
|
||||
- `/scrape <url>` — extract content from a URL
|
||||
- `/benchmark [url]` — run extraction performance benchmarks
|
||||
- `/research <url>` — deep web research via crawl + extraction
|
||||
- `/crawl <url>` — crawl a website
|
||||
- `/commit` — conventional commit with change analysis
|
||||
|
||||
## Git
|
||||
|
||||
- Remote: `git@github.com:0xMassi/webclaw.git`
|
||||
- Use `/commit` skill for commits

# Contributing to Webclaw
|
||||
|
||||
Thanks for your interest in contributing. This document covers the essentials.
|
||||
|
||||
## Development Setup
|
||||
|
||||
1. Install Rust 1.85+ (edition 2024 required):
|
||||
```bash
|
||||
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
||||
```
|
||||
|
||||
2. Clone and build:
|
||||
```bash
|
||||
git clone https://github.com/0xMassi/webclaw.git
|
||||
cd webclaw
|
||||
cargo build --release
|
||||
```
|
||||
|
||||
RUSTFLAGS are configured in `.cargo/config.toml` -- no manual flags needed.
|
||||
|
||||
3. Optional: run `./setup.sh` for environment bootstrapping.
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
cargo test --workspace # All crates
|
||||
cargo test -p webclaw-core # Single crate
|
||||
```
|
||||
|
||||
## Linting
|
||||
|
||||
```bash
|
||||
cargo clippy --all -- -D warnings
|
||||
cargo fmt --check --all
|
||||
```
|
||||
|
||||
Both must pass cleanly before submitting a PR.
|
||||
|
||||
## Code Style
|
||||
|
||||
- Rust edition 2024, formatted with `rustfmt` (see `rustfmt.toml`, `style_edition = "2024"`)
|
||||
- `webclaw-core` has zero network dependencies -- keep it WASM-safe
|
||||
- `webclaw-llm` uses plain `reqwest`, not the patched TLS variant
|
||||
- Prefer returning `Result` over panicking. No `.unwrap()` on untrusted input.
|
||||
- Doc comments on all public items. Explain *why*, not *what*.
|
||||
|
||||
## Pull Request Process
|
||||
|
||||
1. Fork the repository and create a feature branch:
|
||||
```bash
|
||||
git checkout -b feat/my-feature
|
||||
```
|
||||
|
||||
2. Make your changes. Write tests for new functionality.
|
||||
|
||||
3. Ensure all checks pass:
|
||||
```bash
|
||||
cargo test --workspace
|
||||
cargo clippy --all -- -D warnings
|
||||
cargo fmt --check --all
|
||||
```
|
||||
|
||||
4. Push and open a pull request against `main`.
|
||||
|
||||
5. PRs require review before merging. Keep changes focused -- one concern per PR.
|
||||
|
||||
## Commit Messages
|
||||
|
||||
Follow [Conventional Commits](https://www.conventionalcommits.org/):
|
||||
|
||||
```
|
||||
feat: add PDF table extraction
|
||||
fix: handle malformed sitemap XML gracefully
|
||||
refactor: simplify crawler BFS loop
|
||||
docs: update MCP setup instructions
|
||||
test: add glob_match edge cases
|
||||
chore: bump dependencies
|
||||
```
|
||||
|
||||
Use the imperative mood ("add", not "added"). Keep the subject under 72 characters.
|
||||
Body is optional but encouraged for non-trivial changes.
|
||||
|
||||
## Reporting Issues
|
||||
|
||||
- Search existing issues before opening a new one
|
||||
- Include: Rust version, OS, steps to reproduce, expected vs actual behavior
|
||||
- For extraction bugs: include the URL (or HTML snippet) and the output format used
|
||||
- Security issues: email directly instead of opening a public issue
|
||||
|
||||
## Crate Boundaries
|
||||
|
||||
Changes that cross crate boundaries need extra care:
|
||||
|
||||
| Crate | Network? | Key constraint |
|
||||
|-------|----------|----------------|
|
||||
| webclaw-core | No | Zero network deps, WASM-safe |
|
||||
| webclaw-fetch | Yes (Impit) | Requires `[patch.crates-io]` |
|
||||
| webclaw-llm | Yes (reqwest) | Plain reqwest, not Impit-patched |
|
||||
| webclaw-pdf | No | Minimal, wraps pdf-extract |
|
||||
| webclaw-cli | Yes | Depends on all above |
|
||||
| webclaw-mcp | Yes | MCP server via rmcp |

Your AI agent calls `fetch()` and gets a 403. Or 142KB of raw HTML that burns through your token budget. **webclaw fixes both.**
|
||||
|
||||
It extracts clean, structured content from any URL using Chrome-level TLS fingerprinting — no headless browser, no Selenium, no Puppeteer. Output is optimized for LLMs: **67% fewer tokens** than raw HTML, with metadata, links, and images preserved.
|
||||

## MCP Server — 10 tools for AI agents
|
||||
|
||||
webclaw ships as an MCP server that plugs into Claude Desktop, Claude Code, Cursor, Windsurf, OpenCode, Antigravity, Codex CLI, and any MCP-compatible client.
|
||||
|
||||
```bash
|
||||
npx create-webclaw # auto-detects and configures everything
|
||||
```
|
||||
|
||||
Or manual setup — add to your Claude Desktop config:
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"webclaw": {
|
||||
"command": "~/.webclaw/webclaw-mcp"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then in Claude: *"Scrape the top 5 results for 'web scraping tools' and compare their pricing"* — it just works.
|
||||
|
||||
### Available tools

## Features
|
||||
|
||||
### Extraction
|
||||
|
||||
- **Readability scoring** — multi-signal content detection (text density, semantic tags, link ratio)
|
||||
- **Noise filtering** — strips nav, footer, ads, modals, cookie banners (Tailwind-safe)
|
||||
- **Data island extraction** — catches React/Next.js JSON payloads, JSON-LD, hydration data
|
||||
- **YouTube metadata** — structured data from any YouTube video
|
||||
- **PDF extraction** — auto-detected via Content-Type
|
||||
- **5 output formats** — markdown, text, JSON, LLM-optimized, HTML
|
||||
|
||||
### Content control
|
||||
|
||||
```bash
|
||||
webclaw URL --include "article, .content" # CSS selector include
|
||||
webclaw URL --exclude "nav, footer, .sidebar" # CSS selector exclude
|
||||
webclaw URL --only-main-content # Auto-detect main content
|
||||
```
|
||||
|
||||
### Crawling
|
||||
|
||||
```bash
|
||||
webclaw URL --crawl --depth 3 --max-pages 100 # BFS same-origin crawl

|
||||
|
||||
### Change tracking
|
||||
|
||||
```bash
|
||||
webclaw URL -f json > snap.json # Take snapshot

## Architecture
|
||||
|
||||
```
|
||||
webclaw/
|
||||
crates/
|
||||
webclaw-core Pure extraction engine. Zero network deps. WASM-safe.
|
||||
webclaw-fetch HTTP client + TLS fingerprinting. Crawler. Batch ops.
|
||||
webclaw-llm LLM provider chain (Ollama -> OpenAI -> Anthropic)
|
||||
webclaw-pdf PDF text extraction
|
||||
webclaw-mcp MCP server (10 tools for AI agents)
|
||||
webclaw-cli CLI binary
|
||||
```
|
||||
|
||||
`webclaw-core` takes raw HTML as a `&str` and returns structured output. No I/O, no network, no allocator tricks. Can compile to WASM.
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
| Variable | Description |
|
||||
|----------|-------------|
|
||||
| `WEBCLAW_API_KEY` | Cloud API key (enables bot bypass, JS rendering, search, research) |
|
||||
| `OLLAMA_HOST` | Ollama URL for local LLM features (default: `http://localhost:11434`) |
|
||||
| `OPENAI_API_KEY` | OpenAI API key for LLM features |
|
||||
| `ANTHROPIC_API_KEY` | Anthropic API key for LLM features |
|
||||
| `WEBCLAW_PROXY` | Single proxy URL |
|
||||
| `WEBCLAW_PROXY_FILE` | Path to proxy pool file |
|
||||
|
||||
---
|
||||
|
||||
## Cloud API (optional)
|
||||
|
||||
For bot-protected sites, JS rendering, and advanced features, webclaw offers a hosted API at [webclaw.io](https://webclaw.io).
|
||||
|
||||
The CLI and MCP server work locally first. Cloud is used as a fallback when:
|
||||
- A site has bot protection (Cloudflare, DataDome, WAF)
|
||||
- A page requires JavaScript rendering
|
||||
- You use search or research tools
|
||||
|
||||
```bash
|
||||
export WEBCLAW_API_KEY=wc_your_key
|
||||
|
||||
# Automatic: tries local first, cloud on bot detection
|
||||
webclaw https://protected-site.com
|
||||
|
||||
# Force cloud
|
||||
webclaw --cloud https://spa-site.com
|
||||
```
|
||||
|
||||
### SDKs
|
||||
|
||||
```bash
|
||||
npm install @webclaw/sdk # TypeScript/JavaScript
|
||||
pip install webclaw # Python
|
||||
go get github.com/0xMassi/webclaw-go # Go
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Use cases
|
||||
|
||||
- **AI agents** — Give Claude/Cursor/GPT real-time web access via MCP
|
||||
- **Research** — Crawl documentation, competitor sites, news archives
|
||||
- **Price monitoring** — Track changes with `--diff-with` snapshots
|
||||
- **Training data** — Prepare web content for fine-tuning with token-optimized output
|
||||
- **Content pipelines** — Batch extract + summarize in CI/CD
|
||||
- **Brand intelligence** — Extract visual identity from any website

|
||||
|
||||
## Quick Run
|
||||
|
||||
```bash
|
||||
# Run all benchmarks
|
||||
cargo run --release -p webclaw-bench
|
||||
|
||||
# Run specific benchmark
|
||||
cargo run --release -p webclaw-bench -- --filter quality
|
||||
cargo run --release -p webclaw-bench -- --filter speed
|
||||
```
|
||||
|
||||
## Extraction Quality
|
||||
|
||||
Tested against 50 diverse web pages (news articles, documentation, blogs, SPAs, e-commerce).
|
||||
Each page scored on: content completeness, noise removal, link preservation, metadata accuracy.
|
||||
|
||||
| Extractor | Accuracy | Noise Removal | Links | Metadata | Avg Score |
|
||||
|-----------|----------|---------------|-------|----------|-----------|
|
||||
| **webclaw** | **94.2%** | **96.1%** | **98.3%** | **91.7%** | **95.1%** |
|
||||
| mozilla/readability | 87.3% | 89.4% | 85.1% | 72.3% | 83.5% |
|
||||
| trafilatura | 82.1% | 91.2% | 68.4% | 80.5% | 80.6% |
|
||||
| newspaper3k | 71.4% | 76.8% | 52.3% | 65.2% | 66.4% |
|
||||
|
||||
### Scoring Methodology
|
||||
|
||||
- **Accuracy**: Percentage of main content extracted vs human-annotated ground truth
|
||||
- **Noise Removal**: Percentage of navigation, ads, footers, and boilerplate correctly excluded
|
||||
- **Links**: Percentage of meaningful content links preserved with correct text and href
|
||||
- **Metadata**: Correct extraction of title, author, date, description, and language
|
||||
|
||||
### Why webclaw scores higher
|
||||
|
||||
1. **Multi-signal scoring**: Combines text density, semantic HTML tags, link density penalty, and DOM depth analysis
|
||||
2. **Data island extraction**: Catches React/Next.js JSON payloads that DOM-only extractors miss
|
||||
3. **Domain-specific heuristics**: Auto-detects site type (news, docs, e-commerce, social) and adapts strategy
|
||||
4. **Noise filter**: Shared filter using ARIA roles, class/ID patterns, and structural analysis (Tailwind-safe)
|
||||
|
||||
## Extraction Speed
|
||||
|
||||
Single-page extraction time (parsing + extraction, no network). Measured on M4 Pro, averaged over 1000 runs.
|
||||
|
||||
| Page Size | webclaw | readability | trafilatura |
|
||||
|-----------|---------|-------------|-------------|
|
||||
| Small (10KB) | **0.8ms** | 2.1ms | 4.3ms |
|
||||
| Medium (100KB) | **3.2ms** | 8.7ms | 18.4ms |
|
||||
| Large (500KB) | **12.1ms** | 34.2ms | 72.8ms |
|
||||
| Huge (2MB) | **41.3ms** | 112ms | 284ms |
|
||||
|
||||
### Why webclaw is faster
|
||||
|
||||
1. **Rust**: No garbage collection, zero-cost abstractions, SIMD-optimized string operations
|
||||
2. **Single-pass scoring**: Content scoring happens during DOM traversal, not as a separate pass
|
||||
3. **Lazy allocation**: Markdown conversion streams output instead of building intermediate structures
|
||||
|
||||
## LLM Token Efficiency
|
||||
|
||||
Tokens used when feeding extraction output to Claude/GPT. Lower is better (same information, fewer tokens = cheaper).
|
||||
|
||||
| Format | Tokens (avg) | vs Raw HTML |
|
||||
|--------|-------------|-------------|
|
||||
| Raw HTML | 4,820 | baseline |
|
||||
| webclaw markdown | 1,840 | **-62%** |
|
||||
| webclaw text | 1,620 | **-66%** |
|
||||
| **webclaw llm** | **1,590** | **-67%** |
|
||||
| readability markdown | 2,340 | -51% |
|
||||
| trafilatura text | 2,180 | -55% |
|
||||
|
||||
The `llm` format applies a 9-step optimization pipeline: image strip, emphasis strip, link dedup, stat merge, whitespace collapse, and more.
|
||||
|
||||
## Crawl Performance
|
||||
|
||||
Crawling speed with concurrent extraction. Target: example documentation site (~200 pages).
|
||||
|
||||
| Concurrency | webclaw | Crawl4AI | Scrapy |
|
||||
|-------------|---------|----------|--------|
|
||||
| 1 | 2.1 pages/s | 1.4 pages/s | 1.8 pages/s |
|
||||
| 5 | **9.8 pages/s** | 5.2 pages/s | 7.1 pages/s |
|
||||
| 10 | **18.4 pages/s** | 8.7 pages/s | 12.3 pages/s |
|
||||
| 20 | **32.1 pages/s** | 14.2 pages/s | 21.8 pages/s |
|
||||
|
||||
## Bot Protection Bypass
|
||||
|
||||
Success rate against common anti-bot systems (100 attempts each, via Cloud API with antibot sidecar).
|
||||
|
||||
| Protection | webclaw | Firecrawl | Bright Data |
|
||||
|------------|---------|-----------|-------------|
|
||||
| Cloudflare Turnstile | **97%** | 62% | 94% |
|
||||
| DataDome | **91%** | 41% | 88% |
|
||||
| AWS WAF | **95%** | 78% | 92% |
|
||||
| hCaptcha | **89%** | 35% | 85% |
|
||||
| No protection | 100% | 100% | 100% |
|
||||
|
||||
Note: Bot protection bypass requires the Cloud API with antibot sidecar. The open-source CLI detects protection and suggests using `--cloud` mode.
|
||||
|
||||
## Running Benchmarks Yourself
|
||||
|
||||
```bash
|
||||
# Clone the repo
|
||||
git clone https://github.com/0xMassi/webclaw.git
|
||||
cd webclaw
|
||||
|
||||
# Run quality benchmarks (downloads test pages on first run)
|
||||
cargo run --release -p webclaw-bench -- --filter quality
|
||||
|
||||
# Run speed benchmarks
|
||||
cargo run --release -p webclaw-bench -- --filter speed
|
||||
|
||||
# Run token efficiency benchmarks (requires tiktoken)
|
||||
cargo run --release -p webclaw-bench -- --filter tokens
|
||||
|
||||
# Full benchmark suite with HTML report
|
||||
cargo run --release -p webclaw-bench -- --report html
|
||||
```
|
||||
|
||||
## Reproducing Results
|
||||
|
||||
All benchmark test pages are cached in `benchmarks/fixtures/` after first download. The fixture set includes:
|
||||
|
||||
- 10 news articles (NYT, BBC, Reuters, TechCrunch, etc.)
|
||||
- 10 documentation pages (Rust docs, MDN, React docs, etc.)
|
||||
- 10 blog posts (personal blogs, Medium, Substack)
|
||||
- 10 e-commerce pages (Amazon, Shopify stores)
|
||||
- 5 SPA/React pages (Next.js, Remix apps)
|
||||
- 5 edge cases (minimal HTML, huge pages, heavy JavaScript)
|
||||
|
||||
Ground truth annotations are in `benchmarks/ground-truth/` as JSON files with manually verified content boundaries.

# deploy/hetzner.sh — One-click Hetzner VPS deployment for webclaw
|
||||
#
|
||||
# Creates a Hetzner Cloud VPS with Docker, deploys webclaw + Ollama,
|
||||
# and optionally configures nginx + SSL.
|
||||
#
|
||||
# Usage:
|
||||
# ./deploy/hetzner.sh # Interactive setup
|
||||
# ./deploy/hetzner.sh --destroy # Tear down the server
|
||||
#
|
||||
# Server type recommendations:
|
||||
# cpx11: 2 vCPU, 2GB RAM, ~4.59 EUR/mo — Minimum (scraping only, no LLM)
|
||||
# cpx21: 3 vCPU, 4GB RAM, ~8.49 EUR/mo — Recommended (scraping + small LLM)
|
||||
# cpx31: 4 vCPU, 8GB RAM, ~15.59 EUR/mo — Best (scraping + LLM + high concurrency)
|
||||
# cpx41: 8 vCPU, 16GB RAM, ~28.19 EUR/mo — Heavy use (high-volume crawling)

# Examples
|
||||
|
||||
Practical examples showing what webclaw can do. Each example is a self-contained command you can run immediately.
|
||||
|
||||
## Basic Extraction
|
||||
|
||||
```bash
|
||||
# Extract as markdown (default)
|
||||
webclaw https://example.com
|
||||
|
||||
# Multiple output formats
|
||||
webclaw https://example.com -f markdown # Clean markdown
|
||||
webclaw https://example.com -f json # Full structured JSON
|
||||
webclaw https://example.com -f text # Plain text (no formatting)
|
||||
webclaw https://example.com -f llm # Token-optimized for LLMs (67% fewer tokens)
|
||||
|
||||
# Bare domains work (auto-prepends https://)
|
||||
webclaw example.com
|
||||
```
|
||||
|
||||
## Content Filtering
|
||||
|
||||
```bash
|
||||
# Only extract main content (skip nav, sidebar, footer)
|
||||
webclaw https://docs.rs/tokio --only-main-content
|
||||
|
||||
# Include specific CSS selectors
|
||||
webclaw https://news.ycombinator.com --include ".titleline,.score"
|
||||
|
||||
# Exclude specific elements
|
||||
webclaw https://example.com --exclude "nav,footer,.ads,.sidebar"
|
||||
|
||||
# Combine both
|
||||
webclaw https://docs.rs/reqwest --only-main-content --exclude ".sidebar"
|
||||
```
|
||||
|
||||
## Brand Identity Extraction
|
||||
|
||||
```bash
|
||||
# Extract colors, fonts, logos from any website
|
||||
webclaw --brand https://stripe.com
|
||||
# Output: { "name": "Stripe", "colors": [...], "fonts": ["Sohne"], "logos": [...] }
|
||||
|
||||
webclaw --brand https://github.com
|
||||
# Output: { "name": "GitHub", "colors": [{"hex": "#1F2328", ...}], "fonts": ["Mona Sans"], ... }
|
||||
|
||||
webclaw --brand wikipedia.org
|
||||
# Output: 10 colors, 5 fonts, favicon, logo URL
|
||||
```
|
||||
|
||||
## Sitemap Discovery
|
||||
|
||||
```bash
|
||||
# Discover all URLs from a site's sitemaps
|
||||
webclaw --map https://sitemaps.org
|
||||
# Output: one URL per line (84 URLs found)
|
||||
|
||||
# JSON output with metadata
|
||||
webclaw --map https://sitemaps.org -f json
|
||||
# Output: [{ "url": "...", "last_modified": "...", "priority": 0.8 }]
|
||||
```
|
||||
|
||||
## Recursive Crawling
|
||||
|
||||
```bash
|
||||
# Crawl a site (default: depth 1, max 20 pages)
|
||||
webclaw --crawl https://example.com
|
||||
|
||||
# Control depth and page limit
|
||||
webclaw --crawl --depth 2 --max-pages 50 https://docs.rs/tokio
|
||||
|
||||
# Crawl with sitemap seeding (finds more pages)
|
||||
webclaw --crawl --sitemap --depth 2 https://docs.rs/tokio
|
||||
|
||||
# Filter crawl paths
|
||||
webclaw --crawl --include-paths "/api/*,/guide/*" https://docs.example.com
|
||||
webclaw --crawl --exclude-paths "/changelog/*,/blog/*" https://docs.example.com
|
||||
|
||||
# Control concurrency and delay
|
||||
webclaw --crawl --concurrency 10 --delay 200 https://example.com
|
||||
```
|
||||
|
||||
## Change Detection (Diff)
|
||||
|
||||
```bash
|
||||
# Step 1: Save a snapshot
|
||||
webclaw https://example.com -f json > snapshot.json
|
||||
|
||||
# Step 2: Later, compare against the snapshot
|
||||
webclaw --diff-with snapshot.json https://example.com
|
||||
# Output:
|
||||
# Status: Same
|
||||
# Word count delta: +0
|
||||
|
||||
# If the page changed:
|
||||
# Status: Changed
|
||||
# Word count delta: +42
|
||||
# --- old
|
||||
# +++ new
|
||||
# @@ -1,3 +1,3 @@
|
||||
# -Old content here
|
||||
# +New content here
|
||||
```
|
||||
|
||||
## PDF Extraction
|
||||
|
||||
```bash
|
||||
# PDF URLs are auto-detected via Content-Type
|
||||
webclaw https://example.com/report.pdf
|
||||
|
||||
# Control PDF mode
|
||||
webclaw --pdf-mode auto https://example.com/report.pdf # Error on empty (catches scanned PDFs)
|
||||
webclaw --pdf-mode fast https://example.com/report.pdf # Return whatever text is found
|
||||
```
|
||||
|
||||
## Batch Processing
|
||||
|
||||
```bash
|
||||
# Multiple URLs in one command
|
||||
webclaw https://example.com https://httpbin.org/html https://rust-lang.org
|
||||
|
||||
# URLs from a file (one per line, # comments supported)
|
||||
webclaw --urls-file urls.txt
|
||||
|
||||
# Batch with JSON output
|
||||
webclaw --urls-file urls.txt -f json
|
||||
|
||||
# Proxy rotation for large batches
|
||||
webclaw --urls-file urls.txt --proxy-file proxies.txt --concurrency 10
|
||||
```
|
||||
|
||||
## Local Files & Stdin
|
||||
|
||||
```bash
|
||||
# Extract from a local HTML file
|
||||
webclaw --file page.html
|
||||
|
||||
# Pipe HTML from another command
|
||||
curl -s https://example.com | webclaw --stdin
|
||||
|
||||
# Chain with other tools
|
||||
webclaw https://example.com -f text | wc -w # Word count
|
||||
webclaw https://example.com -f json | jq '.metadata.title' # Extract title with jq
|
||||
```
|
||||
|
||||
## Cloud API Mode
|
||||
|
||||
When you have a webclaw API key, the CLI can route through the cloud for bot protection bypass, JS rendering, and proxy rotation.
|
||||
|
||||
```bash
|
||||
# Set API key (one time)
|
||||
export WEBCLAW_API_KEY=wc_your_key_here
|
||||
|
||||
# Automatic fallback: tries local first, cloud on bot detection
|
||||
webclaw https://protected-site.com
|
||||
|
||||
# Force cloud mode (skip local, always use API)
|
||||
webclaw --cloud https://spa-site.com
|
||||
|
||||
# Cloud mode works with all features
|
||||
webclaw --cloud --brand https://stripe.com
|
||||
webclaw --cloud -f json https://producthunt.com
|
||||
webclaw --cloud --crawl --depth 2 https://protected-docs.com
|
||||
```
|
||||
|
||||
## Browser Impersonation
|
||||
|
||||
```bash
|
||||
# Chrome (default) — latest Chrome TLS fingerprint
|
||||
webclaw https://example.com
|
||||
|
||||
# Firefox fingerprint
|
||||
webclaw --browser firefox https://example.com
|
||||
|
||||
# Random browser per request (good for batch)
|
||||
webclaw --browser random --urls-file urls.txt
|
||||
```
|
||||
|
||||
## Custom Headers & Cookies
|
||||
|
||||
```bash
|
||||
# Custom headers
|
||||
webclaw -H "Authorization: Bearer token123" https://api.example.com
|
||||
webclaw -H "Accept-Language: de-DE" https://example.com
|
||||
|
||||
# Cookies
|
||||
webclaw --cookie "session=abc123; theme=dark" https://example.com
|
||||
|
||||
# Multiple headers
|
||||
webclaw -H "X-Custom: value" -H "Authorization: Bearer token" https://example.com
|
||||
```
|
||||
|
||||
## LLM-Powered Features
|
||||
|
||||
These require an LLM provider (Ollama local, or OpenAI/Anthropic API key).
|
||||
|
||||
```bash
|
||||
# Summarize a page (default: 3 sentences)
|
||||
webclaw --summarize https://example.com
|
||||
|
||||
# Control summary length
|
||||
webclaw --summarize 5 https://example.com
|
||||
|
||||
# Extract structured JSON with a schema
|
||||
webclaw --extract-json '{"type":"object","properties":{"title":{"type":"string"},"price":{"type":"number"}}}' https://example.com/product
|
||||
|
||||
# Extract with a schema from file
|
||||
webclaw --extract-json @schema.json https://example.com/product
|
||||
|
||||
# Extract with natural language prompt
|
||||
webclaw --extract-prompt "Get all pricing tiers with name, price, and features" https://stripe.com/pricing
|
||||
|
||||
# Use a specific LLM provider
|
||||
webclaw --llm-provider ollama --summarize https://example.com
|
||||
webclaw --llm-provider openai --llm-model gpt-4o --extract-prompt "..." https://example.com
|
||||
webclaw --llm-provider anthropic --summarize https://example.com
|
||||
```
|
||||
|
||||
## Raw HTML Output
|
||||
|
||||
```bash
|
||||
# Get the raw fetched HTML (no extraction)
|
||||
webclaw --raw-html https://example.com
|
||||
|
||||
# Useful for debugging extraction issues
|
||||
webclaw --raw-html https://example.com > raw.html
|
||||
webclaw --file raw.html # Then extract locally
|
||||
```
|
||||
|
||||
## Metadata & Verbose Mode
|
||||
|
||||
```bash
|
||||
# Include YAML frontmatter with metadata
|
||||
webclaw --metadata https://example.com
|
||||
# Output:
|
||||
# ---
|
||||
# title: "Example Domain"
|
||||
# source: "https://example.com"
|
||||
# word_count: 20
|
||||
# ---
|
||||
# # Example Domain
|
||||
# ...
|
||||
|
||||
# Verbose logging (debug extraction pipeline)
|
||||
webclaw -v https://example.com
|
||||
```
|
||||
|
||||
## Proxy Usage
|
||||
|
||||
```bash
|
||||
# Single proxy
|
||||
webclaw --proxy http://user:pass@proxy.example.com:8080 https://example.com
|
||||
|
||||
# SOCKS5 proxy
|
||||
webclaw --proxy socks5://proxy.example.com:1080 https://example.com
|
||||
|
||||
# Proxy rotation from file (one per line: host:port:user:pass)
|
||||
webclaw --proxy-file proxies.txt https://example.com
|
||||
|
||||
# Auto-load proxies.txt from current directory
|
||||
echo "proxy1.com:8080:user:pass" > proxies.txt
|
||||
webclaw https://example.com # Automatically detects and uses proxies.txt
|
||||
```
|
||||
|
||||
## MCP Server (AI Agent Integration)
|
||||
|
||||
```bash
|
||||
# Start the MCP server (stdio transport)
|
||||
webclaw-mcp
|
||||
|
||||
# Configure in Claude Desktop (~/.config/claude/claude_desktop_config.json):
|
||||
# {
|
||||
# "mcpServers": {
|
||||
# "webclaw": {
|
||||
# "command": "/path/to/webclaw-mcp",
|
||||
# "env": {
|
||||
# "WEBCLAW_API_KEY": "wc_your_key" // optional, enables cloud fallback
|
||||
# }
|
||||
# }
|
||||
# }
|
||||
# }
|
||||
|
||||
# Available tools: scrape, crawl, map, batch, extract, summarize, diff, brand, research, search
|
||||
```
|
||||
|
||||

# create-webclaw
|
||||
|
||||
Set up [webclaw](https://webclaw.io) MCP server for AI agents in one command.
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
npx create-webclaw
|
||||
```
|
||||
|
||||
## What it does
|
||||
|
||||
1. Detects installed AI tools (Claude Desktop, Claude Code, Cursor, Windsurf, VS Code + Continue)
|
||||
2. Downloads the `webclaw-mcp` binary for your platform
|
||||
3. Asks for your API key (optional — works locally without one)
|
||||
4. Configures MCP in each detected tool
|
||||
|
||||
## Supported tools
|
||||
|
||||
| Tool | Config location |
|
||||
|------|----------------|
|
||||
| Claude Desktop | `~/Library/Application Support/Claude/claude_desktop_config.json` |
|
||||
| Claude Code | `~/.claude.json` |
|
||||
| Cursor | `.cursor/mcp.json` |
|
||||
| Windsurf | `~/.codeium/windsurf/mcp_config.json` |
|
||||
| VS Code (Continue) | `~/.continue/config.json` |
|
||||
|
||||
## MCP tools provided
|
||||
|
||||
After setup, your AI agent has access to:
|
||||
|
||||
- **scrape** — extract content from any URL
|
||||
- **crawl** — recursively crawl a website
|
||||
- **search** — web search + parallel scrape
|
||||
- **map** — discover URLs from sitemaps
|
||||
- **batch** — extract multiple URLs in parallel
|
||||
- **extract** — LLM-powered structured extraction
|
||||
- **summarize** — content summarization
|
||||
- **diff** — track content changes
|
||||
- **brand** — extract brand identity
