Free Chrome extension
See what any GitHub PR really touches.
Reviewing an unfamiliar change means holding somebody else's dependency graph in your head. Striff draws it for you, in a tab right beside Files changed, so you see what a change touches before you approve it. The rules that repository states in its own documents are checked while the diagram renders and drawn onto it, so the intent sits beside the code. You never leave GitHub.
- An interactive dependency diagram of any public PR
- Its documented rules checked and drawn on that diagram
- Comment straight from the diagram
- No backend, and your token stays local
Extension or App
One is for you. The other is for the team.
Both read the documents and answer the rules. The difference is who sees it and when. The extension is one person, one pull request, on demand, on any public repository you happen to be looking at. The App runs on every pull request your team opens, posts the result where the whole team reviews, and keeps the history that becomes your dashboard.
Do I need to install anything on the repository?
No. The extension runs in your browser on any public pull request you visit, so you can point it at somebody else's repository without touching it. Bring a free GitHub token for rate limits; it never leaves your browser.
Does the extension check documented rules too?
Yes. The review starts on its own as the diagram renders, and the headline above the graph goes from “Checking documented rules…” to a count: how many rules that repository's own documents state, and how many are at risk on this change. The rules that concern a drawn component are boxed on the diagram itself, and “View review” opens the full list beside it. Same pipeline as the GitHub App, on a repository you do not have to own.
Is it free?
Yes, on every public pull request, with no account.
