Code review

AI software engineers that review every pull request

Code review that doesn't just find issues. It solves them.

Triggered on every PR. Ona compiles, runs tests, catches issues, and iterates on fixes — before your team starts reviewing.

Reviews in a real environment

Not a linter. A reviewer that compiles and tests.

Most AI review tools work from the diff alone.

Ona clones the repo, builds it, runs tests, and reviews with full context — catching what static analysis never will.

Cloned repo, compiled project, ran tests, reviewed files
Your rules, your standards

Configured to review the way your team would.

Your coding standards, compliance requirements, and architectural patterns — codified and enforced on every review.

No drift between teams. No rules that only exist in your staff engineer's head.

Fixes, not just flags

Doesn't just comment. Pushes fixes and iterates.

When Ona finds an issue, it doesn't just tell you.

It fixes the code, reruns the tests, and iterates until builds pass. PRs arrive ready to review, not ready to debug.

Every PR, every repo

Triggered on every PR. Or before you open one.

Runs automatically on every PR across your org — no per-repo setup.

Or let developers trigger a review before they push, while they're still in context.

PR triggered review across repos
Audit ready by design

Every review is logged and traceable.

Each review runs in an isolated environment with scoped credentials and full logging.

What was checked, what was flagged, what was approved — all recorded automatically for compliance.
