AI code review that checks PRs against your whole codebase
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
cubic gives inline feedback on every PR, flags changes that break code elsewhere, and turns past review comments from senior engineers into rules. It also runs codebase scans, background fixes and a terminal review before you push, and says it never stores code or trains on it. The pricing page was not readable during review, so confirm plan limits with the vendor before buying.
Our verdict
Promising for teams that want learned review rules and codebase scans. Its benchmark claims come from the vendor, so test it on your own PRs.
