AI software engineers that review every pull request

Code review that can compile, run tests, and fix

Every PR reviewed by an agent in a secure sandbox with a full toolchain. Ona builds the code, runs the tests and catches what static code review tools can't.

Reviews in a real environment

Reviews by running your app, like an engineer

Instead of comparing a diff, Ona runs your application in an isolated environment and reviews it the way an engineer would, catching integration breaks and logic errors static tools miss.

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

Configured to your team's standards

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

The rules that used to live only in your staff engineer's head apply consistently across every team.

Fixes, not just flags

Iterates until the build is green

When Ona finds an issue it fixes the code, reruns the tests, and keeps iterating until the build passes.

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 with 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, so what was checked, flagged, and approved is recorded automatically for compliance.
