See the dependencies between your repos —
even the ones nobody documented.

Untangle clones every repo from your GitLab, GitHub, or any git host, statically maps how they depend on each other, and serves an interactive graph — so you finally know what breaks when something changes.

Everything coupling hides from you

Most dependency tools stop at one repo's lockfile. Untangle works across all of them.

Declared and undocumented

npm/pip/go manifests, Dockerfiles, CI includes and Terraform sources — plus hardcoded internal URLs in source, resolved back to the repo that serves them.

Blast radius

Click any component to see the transitive set of repos that break if it fails. The shared core lights up exactly how scary it should.

Multi-ecosystem

Node, Python, Go, Docker, Terraform and GitLab CI out of the box — one graph across every language and runtime in your org.

Self-hosted & private

Your code never leaves your network. The analyzer clones shallow, reads working trees, and writes a single JSON. That's it.

Zero-config to start

Point it at one origin and go. Systems are synthesized from repo groups; detection patterns derive from your hosts. Tune later with YAML.

No build step, no CDN

A static nginx app and a Python analyzer joined by JSON. Vanilla JS + Cytoscape, fully offline. The page you're on runs the same engine.

Up and running in one command

  1. 1

    Point it at your repos

    A GitLab instance, a GitHub org/user, or an explicit list of git URLs — or any mix. One line in .env.

  2. 2

    Analyze

    It shallow-clones every repo, runs the ecosystem parsers and route extractors, and writes one graph.json.

  3. 3

    Explore

    Open the dashboard: shared-components core, per-system clusters, hover path-tracing, and blast radius.

bash
cp .env.example .env
# one line is enough, e.g. GITHUB_ORG=my-org  (or GITLAB_URL=… + token)

docker compose up -d --build
# open http://localhost:8080

Free, forever, and yours to run
