Reddit blocks wreq's Chrome 145 BoringSSL fingerprint at the JA3/JA4
TLS layer even though our HTTP headers correctly impersonate Chrome.
Curl from the same machine with the same Chrome User-Agent string
returns 200 from Reddit's .json endpoint; webclaw with the Chrome
profile returns 403. The detector clearly fingerprints below the
header layer.
Tested all six vertical extractors with the Firefox profile:
reddit, hackernews, github_repo, pypi, npm, huggingface_model all
return correct typed JSON. Firefox is a strict improvement on the
Chrome default for sites with active TLS-level bot detection, with
no regressions on the API-flavored sites that were already working.
Real fix is per-extractor preferred profile, but the structural
change to allow per-call profile selection in FetchClient is a
larger refactor. Flipping the global default is a one-line change
that ships the unblock now and lets users hit the new
/v1/scrape/{vertical} routes against Reddit immediately.
Self-hosters hitting docs/self-hosting were promised three binaries
but the OSS Docker image only shipped two. webclaw-server lived in
the closed-source hosted-platform repo, which couldn't be opened. This
adds a minimal axum REST API in the OSS repo so self-hosting actually
works without pretending to ship the cloud platform.
Crate at crates/webclaw-server/. Stateless, no database, no job queue,
single binary. Endpoints: GET /health, POST /v1/{scrape, crawl, map,
batch, extract, summarize, diff, brand}. JSON shapes mirror
api.webclaw.io for the endpoints OSS can support, so swapping between
self-hosted and hosted is a base-URL change.
Auth: optional bearer token via WEBCLAW_API_KEY / --api-key. Comparison
is constant-time (subtle::ConstantTimeEq). Open mode (no key) is
allowed and binds 127.0.0.1 by default; the Docker image flips
WEBCLAW_HOST=0.0.0.0 so the container is reachable out of the box.
Hard caps to keep naive callers from OOMing the process: crawl capped
at 500 pages synchronously, batch capped at 100 URLs / 20 concurrent.
For unbounded crawls or anti-bot bypass the docs point users at the
hosted API.
Dockerfile + Dockerfile.ci updated to copy webclaw-server into
/usr/local/bin and EXPOSE 3000. Workspace version bumped to 0.4.0
(new public binary).
