Ito is an AI code review tool that builds your app on every pull request, runs the flows your change touches, and posts proof when something breaks.
About Ito
What Is Ito
Ito is a runtime testing layer for engineering teams. Instead of only reading a diff, it builds and runs your application from source, then navigates the product the way a real user would: signing in, filling forms, submitting, and checking that the backend does what the change intended. It performs pull request testing on the running app rather than on the code as written.
The problem it solves is the gap between code that looks fine and code that works. A diff can pass review and still break in production when real data moves through the system. Ito targets those bugs by testing frontend and backend as one running system, not as isolated files.
The tool isn't a merge bot and it doesn't replace strategic QA. Ito reviews, you decide. It also focuses on web apps and APIs right now, with native mobile on the roadmap rather than in the product today.
Getting Started
- An admin on your GitHub organization installs Ito and connects the repository you want tested.
- Add plain-English instructions about what matters most to your team, such as security, accessibility, or mobile usability.
- Open a pull request as usual. Ito reads the diff and description, then builds a targeted test plan on its own.
- Review the results in the PR comment or the Ito dashboard, where you get video, logs, and a fix prompt for anything that broke.

Key features
Targeted Test Plans
When a PR opens, Ito reads the diff and the PR description, then maps the change to the user journeys it could put at risk. It builds the test plan on its own, so there are no test cases to write and no suite to maintain. You can add plain-English instructions to steer what it prioritizes.
Containerized Test Execution
For every pull request, Ito deploys your application in a clean, single-use container built for that change. The container runs your real code rather than a mock or a snapshot, and it's destroyed once the run finishes, so nothing carries over. That isolation is what makes the results trustworthy.
Runtime Frontend and Backend Testing
Ito navigates your app like a real user and exercises the backend at the same time. It catches the bugs that only appear when both sides run together and real requests move through the app, such as timing, state, and integration bugs that static review can't see.
Evidence on Every Finding
When Ito finds a problem, it posts a comment on the PR with the exact lines involved, the severity, reproduction steps, a video replay, and a simple prompt to fix it. Your team triages it like any other review comment, with proof attached instead of a vague warning.
Adaptive Learning Over Time
Ito watches which bugs your team fixes, which you close as won't fix, and the feedback you give on past plans. It treats code review automation as something that improves with use, not a fixed ruleset. It uses that signal to weight future tests, so a team shipping auth-heavy changes gets sharper auth coverage the longer it uses the tool.
Security and Data Isolation
Ito is SOC 2 Type II compliant, encrypts traffic with TLS 1.2 or higher, and encrypts customer data at rest with AES-256. Customer data is logically segregated, and access to production systems requires SSO with mandatory multi-factor authentication.
Pros and cons
Pros
- Tests frontend and backend as one running system for regression testing, which catches runtime bugs that diff-only reviewers miss.
- No test cases to write or maintain, so there are no selectors to break when markup changes.
- Posts video, logs, and reproduction steps with each finding, cutting the time spent reproducing failures by hand.
- Free first 20 reviews and a free tier for qualified open-source projects lower the cost of trying it.
Cons
- Only supports web apps and APIs today. Teams that need native mobile testing have to wait for the roadmap.
- Reviews typically take 30 minutes to 2 hours, so it isn't instant feedback on small changes.
- It doesn't merge code for you. You still need to wire it into your own merge process.
- The Pro plan charges per additional review past 50 per seat, which can add up for very high-volume teams.
