We make AI code
safe to ship.

runlit is AI code eval infrastructure — the trust layer sitting below your AI IDE and inside every CI/CD pipeline.

AI coding assistants are remarkably productive. They're also confidently wrong in ways that are hard to catch: hallucinated APIs that don't exist, logic that subtly contradicts the original intent, security patterns that introduce vulnerabilities, and compliance violations that only surface in production.

We built runlit to intercept exactly that. Four signals — hallucination, intent, security, and compliance — run in parallel on every PR, scored and graded before a human ever reviews the diff.

Built for engineering teams

runlit integrates where your workflow already lives: as a GitHub App, a GitHub Action, a CLI, and a VS Code extension. No new tab to open, no dashboard to check — just a score on every PR and a blocking check when something is wrong.

Free to start

Install the GitHub App, add a .runlit.yml to your repo, and your first eval runs in under 30 seconds. No credit card required.
