Graph-powered PR intelligence

Merge any code change
fearlessly. In one click.

AI writes code fast, but it doesn't know your repo's hidden rules. Tangle reads your Git history to tell you exactly what will break and what you forgot before you merge.

Or try a live repository:

co-changed 47×✦ ships together✦ no visible code link✦ hidden coupling found✦ blast radius mapped✦ bounds, not guesses✦ reviewer auto-routed✦ bounded, not proven✦

Mapping hidden dependencies on world-class repositories

Stop guessing.

Semantic search tells you files feel related. Tangle checks every historical commit pair in your repo and shows the receipts.

Vector RAG search “seems related…”

Embedding similarity. No history, no confidence, no proof. Hope it doesn't break prod.

Tangle + FalkorDB co-changed 47×

✓ Clean within bounds — not proof

Made for the way you merge

Pick your chaos. Tangle has already mapped it.

One graph. Every hidden rule.

Whether you're touching a router, a workflow, or a forgotten locale file — Tangle adapts to how your repo actually evolves, not how it's documented.

The Ripple Effect

See exactly which files usually change when you touch this code, ranked by risk. No more surprise bugs in production.

👻

Hidden Connections

Did you forget a config file? Tangle catches files that always ship together but have no visible code connection.

🎯

Smart Routing

Find the right reviewer instantly. We route your PR to the person who actually owns the history of the affected files.

Blast radius, ranked by real risk.

Every touched file scores by how often it historically co-changed with your edit — with the commit receipts to back it up. Thresholds are yours to set.

Reviewers who actually own the history.

Not commit counts — ownership. Tangle ranks reviewers by how much of the affected blast radius they've personally touched before.

Vector RAG guesses.
Tangle proves it.

Other tools use semantic search to guess connections. Tangle uses FalkorDB to map millions of historical commits and state exactly how much of the graph it searched to reach its answer. If it's clean, we show the bounds that claim rests on.
