Omnigraph

Typed graph engine as knowledge/context layer for agents.

Git-style workflows, schema-as-code graph modeling, S3-optimized.

Vector/FTS/Graph queries in one runtime.

Use Cases

• On-prem & hybrid context graphs
• Backbone for multi-agentic research
• Enterprise knowledge systems

Quick Install

curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/install.sh | bash

This installs omnigraph and omnigraph-server into ~/.local/bin from published release binaries.

Or install with Homebrew:

brew tap ModernRelay/tap
brew install ModernRelay/tap/omnigraph

For starter graphs and agent skills to bootstrap and operate Omnigraph, see ModernRelay/omnigraph-starters.

One-Command Local RustFS Bootstrap

curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash

That bootstrap:

• starts RustFS on 127.0.0.1:9000
• creates a bucket and S3-backed repo
• loads the checked-in context fixture
• launches omnigraph-server on 127.0.0.1:8080

Docker must be installed and running first.

The RustFS bootstrap prefers the rolling edge binaries and only falls back to source builds when release assets are unavailable.

If a previous run left objects under the same repo prefix but did not finish initializing the repo, rerun with RESET_REPO=1 or set PREFIX to a new value.

Omnigraph CORE

• Typed schema, typed queries, and typed mutations
• Schema-as-code, query validation and linting
• Git-style graph workflows: branches, commits, merges, and transactional runs
• Local, on-prem & cloud S3-native storage with snapshot-pinned reads
• Graph traversal + text, fuzzy, BM25, vector, and RRF search in one runtime
• Policy-as-code for server-side access control
• Single CLI for multiple deployments

Common Commands

The same URI works for local paths, s3://…, or http://host:port.

omnigraph init   --schema ./schema.pg ./repo.omni
omnigraph load   --data   ./data.jsonl ./repo.omni
omnigraph read   --query  ./queries.gq --name get_person --params '{"name":"Alice"}' ./repo.omni
omnigraph change --query  ./queries.gq --name insert_person --params '{"name":"Mina"}' ./repo.omni
omnigraph branch create --from main feature-x ./repo.omni
omnigraph branch merge  feature-x --into main ./repo.omni

See docs/cli.md for schema apply, snapshots, ingest, runs, and policy commands.

Build And Test

cargo build --workspace
cargo check --workspace
cargo test --workspace

Notes:

• Rust stable toolchain, edition 2024
• CI runs cargo test --workspace --locked
• Full CI and some local test flows require protobuf-compiler
• S3 integration tests expect an S3-compatible endpoint such as RustFS

Workspace Crates

• crates/omnigraph-compiler: shared schema/query parser, typechecker, catalog, and IR lowering
• crates/omnigraph: storage/runtime, branching, merge, change detection, and query execution
• crates/omnigraph-cli: CLI for init/load/ingest/read/change/branch/snapshot/export/policy operations
• crates/omnigraph-server: Axum HTTP server for remote reads, changes, ingest, export, branches, commits, and runs
