Ito

Overview

Ito is an AI code checker built around runtime verification instead of static review comments. When a pull request opens, Ito reads the diff and PR description, builds a fresh copy of the application, runs the user flows most likely to be affected, and posts the result back to GitHub with evidence.

That positioning matters because agent-written code is increasing PR volume. Traditional review tools can reason about source code, but many regressions only appear when the application is actually running: authentication, service authorization, data migration, form behavior, concurrency, and failure handling. Ito is designed to catch those runtime bugs before merge.

The product is best evaluated as an automated QA layer for engineering teams already using AI code generators or coding agents. It does not replace human architecture review, security review, or product judgment, but it can reduce the manual regression clicking that often slows down PR review.

Key Features

• Runtime pull request testing - Ito builds a single-use copy of your app for every PR and tests behavior in a real browser instead of only commenting on the diff.
• Targeted test planning - It reads the PR diff and description, then focuses testing on user journeys that the change is likely to affect.
• Evidence-rich GitHub comments - Findings include video replay, logs, screenshots, reproduction steps, severity, and affected code lines, so developers can reproduce and fix issues faster.
• Fix confirmation - When a developer pushes a fix, Ito can re-run the relevant checks to confirm the issue is resolved before merge.
• Agent sandbox support - Ito gives agents a managed copy of the application to build and test against, which is useful when coding agents create or modify features.
• Custom rules and team analytics - Paid plans include custom rules plus team insights and analytics for tracking review coverage.

How to Get Started

1. Connect GitHub - Install Ito for the repositories where you want runtime pull request review.
2. Define test priorities - Add plain-English instructions for important flows, user roles, edge cases, or areas Ito should avoid.
3. Open a pull request - Ito reads the diff, builds the app, and creates a targeted test plan.
4. Review evidence in GitHub - Developers see pass/fail summaries, videos, logs, and reproduction steps directly on the PR.
5. Push a fix and re-run - Ito re-checks fixes so reviewers can merge with stronger behavioral evidence.

Pricing & Plans

Ito offers a paid Pro plan, custom Enterprise plan, and free access for approved open-source projects.

The Pro plan includes unlimited repositories, unlimited read-only users, custom rules, team insights, and analytics. Teams should confirm included review counts and overage rules before rolling Ito across many active repositories.

Best For

• Engineering teams using AI coding agents and needing runtime verification before merge.
• Startups that want automated browser-based PR testing without maintaining every Playwright test by hand.
• Reviewers who need videos, logs, screenshots, and reproduction steps rather than assertion-only AI comments.
• Teams comparing tools like Claude Code, Cursor, and other agent workflows where generated code needs fast validation.
• Open-source maintainers with MIT or Apache projects that qualify for Ito's free plan.
