OpenMergeLens: AI code reviews on your machine.
OpenMergeLens finds open GitHub pull requests with an active review request for your account, runs the reviewer agent you choose, and posts anchored, inline feedback without a GitHub App, webhook, or hosted server. Requests can be manual or supplied by CODEOWNERS.

Found 3 anchored findingsYour reviewer, your machine
OpenMergeLens is a small local CLI, not another hosted bot. It works with Claude Code, Codex, or any compatible reviewer command and uses your existing GitHub CLI authentication.
Choose the reviewer
Use Claude Code, Codex, or another compatible CLI. The polling workflow never hardcodes a single model provider.
Real inline findings
Findings are validated against actual diff lines before posting. Unanchored feedback is preserved in the review summary.
From request to review
A deterministic polling loop handles requested reviews and avoids duplicate comments. New commits on a previously reviewed pull request wait for the author to request another review.
