AI code reviews for complex codebases.
cubic is an AI code review tool that checks pull requests against the whole codebase and the team's standards to catch bugs and changes that break code elsewhere. It can auto-approve safe changes, score each PR's merge safety, and pass its feedback to coding agents such as Claude Code, Codex and Cursor for fixes. It also runs scheduled background scans for bugs and vulnerabilities.
