AI writes the code.
Who proves it works?

AI teams ship 10× more PRs. Review time went up 91%. The bottleneck isn’t the code — it’s humans manually verifying it.

Opslane verifies behavior on every PR — and locally while you build. Merge with confidence, not hope.

The new reality

Your CI is green. Your tests pass.
Still don’t know if it works.

Code review made sense when humans wrote every line. Now your coding agent opens 10 PRs before lunch. You can’t read them all. You approve them anyway — and hope nothing breaks in prod.

That’s not a process problem. That’s a paradigm mismatch.

How it works

Your new first reviewer.

Runs on every PR. Runs locally while you build. No tests to write.

01

Sandbox

Opslane spins up your app from the PR branch in an isolated container. Nothing touches production. Works the same locally — run it while your agent is still writing.

$ creating sandbox...
$ cloning repo → installing deps
✓ sandbox ready
02

Run

A real browser crawls your app, discovers every route, and executes the flows that matter. No test scripts to write — Opslane figures out what to check.
