Catch runtime errors no one else can
Avoid incidents by catching runtime bugs early: concurrency, failure handling, data migration, authentication
Catch all runtime bugs before merge.
Ito is the only AI code review tool that builds your app on every PR, runs the impacted flows, and attaches the failing test to anything that breaks. Before it merges
Trusted by engineering teams at
Ship faster than everwithout sacrificing quality
Detailed proof on every finding
Thorough runtime evidence on every pull request: video, logs, reproduction steps, re-run on fix, prompt to fix
Removes the worst 3 hours of your week
Automate the time each developer spends manually verifying AI code for runtime issues, with evidence
how ito works
Ship fast, test automatically
Targeted test plans
- When a PR opens, Ito reads the diff and the PR description, then focuses its testing on the user flows your change affects
- It builds the plan on its own, no test cases to write and no suite to maintain
- Add plain-English test instructions to prioritize the scenarios that matter and skip the ones that don't
Containerized test execution
- For every PR, Ito builds and runs a real, single-use copy of your app from source
- Ito navigates your app like a real user, and every action runs your real backend code, surfacing the logic and data bugs code review can't catch by reading the diff
- Beyond the happy path, it runs the edge cases and adversarial scenarios that real-world use exposes
Full findings, right in your PR
- Every PR gets a complete test summary: which flows passed, which failed, and exactly what Ito did to find out
- Every failure includes everything you need to fix it fast: a video replay, the exact lines responsible, and steps to reproduce.
- Severity ratings tell you what to tackle first, so you're not guessing what matters most
- Push a fix and Ito automatically re-runs to confirm it's resolved
WHY ITO
Nothing runs the code before it merges
AI now writes most of the code in a pull request. Every tool that checks that code reads it. Reviewers, linters, static analyzers, AI review bots: all of them reason about the diff and none of them execute it. The first thing that actually runs your change is production. We built Ito to be the thing that runs it first.
The problem: review without execution
- The PR volume from coding agents has outgrown what any team can verify by hand. The choice has become merge on faith or become the bottleneck.
- AI reviewers post confident comments, but a comment is an assertion. Nobody knows which ones are real until someone reproduces them, which is its own job.
- The bugs that reach production are the ones a diff can't show: the retry that authorizes a payment twice, the rescue that doesn't cover the failure, the migration that renames a live column. They only exist when the code runs.
The solution: execution as infrastructure
- On every PR, Ito builds a disposable copy of your app from source and exercises the flows your change touches, through the UI, against your real backend code.
- Anything that breaks arrives as a failing test with video, logs, and repro steps attached to the PR. Not an opinion about the code. A recording of it failing.
- Push a fix and Ito re-runs until it passes. Your engineers read results instead of hunting for them, and the merge decision rests on evidence.
Nothing in the code diff in the PR that Ito reviewed had any direct sign of this bug. If Ito had only been looking at the diff lines from the PR, then it wouldn't have caught this.
