Compare MergeSafe

Last updated 12 November 2026.

How is MergeSafe different from other AI code reviewers?

Most AI code reviewers comment on your pull request. MergeSafe does that too, and then decides whether it is safe to merge: a review, a dependency gate for malicious and known-vulnerable packages, and a merge-readiness score you can make a required check, priced per review with no seats.

What MergeSafe adds to a review

• A dependency gate, free. Flags a known-vulnerable (CVE) or malicious npm or PyPI version on every pull request, with or without a review. Advisory by default; an admin can make it blocking.
• A merge-readiness score and a check you can require. The mergesafe-review check fails while a P0 or P1 finding is open.
• An advisory check. When a new security advisory names a package you use, MergeSafe reads your code to see if you are affected.
• Sentry errors into issues and, if you turn it on, tested fixes.
• Per-review pricing. No seats, a prepaid balance and spending limits. See Pricing.
