comber check<br>live · one run, cheap replays

One expensive run. Then deterministic replays.

47 clicks<br>Explores every reachable state like a real user — no test scripts.

$0.01 a run<br>DOM-first, vision only when it has to. Cents, not dollars, per crawl.

41 seconds<br>Fits inside CI, on every preview deploy, before your users get there.

Why comber

Writing end-to-end tests is a second job.

Scripted tests only catch what you thought to script — and they rot the moment the UI moves. comber explores your app like a person and finds what you didn't know to look for.

the old way

— Write and maintain Playwright / Cypress scripts by hand

— They break every time a selector moves

— They only test the paths you remembered

— A green suite still ships the bug nobody scripted

with comber

✓ Point it at a URL — no scripts to write

✓ It clicks every reachable state like a real user

✓ Catches the broken click you never thought to test

✓ Files it with a repro, screenshot, and trace

How it works

Three steps, on every preview deploy.

01<br>Point it at a URL<br>Drop comber check into CI, or connect a repo and let it fire on every preview deploy. Bring your own key, or let us run it.

02<br>It explores like a user<br>DOM-first, vision only when it needs it — comber clicks, types, and navigates every reachable state, watching the console, network, and accessibility tree.

03<br>You get the receipts<br>Every finding lands with a repro, a screenshot, and a trace — plus cheap deterministic replays, so the expensive run happens once.

What you get

Every click, checked — for cents.

Every-click coverage<br>Not the happy path you scripted — every reachable state, explored like a real user.

Real repros<br>Each finding ships with the exact steps, a screenshot, and a trace you can replay.

Runs in your CI<br>One line in GitHub Actions, GitLab, or any CI — fires on every preview deploy.

Cheap and fast<br>DOM-first keeps it at cents per run and inside your CI budget — vision only when needed.

More than broken clicks<br>Catches server errors, failed requests, and accessibility breaks — not just dead buttons.

Your key or ours<br>Bring your own Anthropic or OpenAI key, or let us run the whole thing on our infra.
