AI PR reviewer
Free tier + paidCode review, testing & securitycoderabbit.ai
What it is
Line-by-line AI review bot that comments on every pull request with a summary, a change walkthrough and inline suggestions carrying one-click fixes. It runs linters and SAST engines underneath, supports agentic chat in the PR thread, and adds pre-merge checks. Also ships a CLI and IDE extension.
Why it earns a slot
It reads the whole diff before you merge agent-written code, catching the null deref, the swallowed error and the hardcoded credential an AI confidently produced. Free on public repos means there is no excuse to skip review.
Know before you commit
Comment volume is high by default on large diffs. Tune path filters and set the review profile to 'chill' in
.coderabbit.yaml or the noise trains you to ignore it.Getting started
