cubic
AI code reviews for complex codebases
cubic is an AI code review tool that checks pull requests and the wider codebase for hard-to-find bugs, including issues that extend beyond the changed diff. It aims to reduce review bottlenecks by surfacing problems before merge and by scanning repositories for bugs and security issues on an ongoing basis.
Core capabilities include inline PR feedback, auto-approvals for low-risk changes, a merge confidence score, custom review rules written in plain English, and a CLI for reviewing before pushing. It integrates with coding agents such as Claude Code, Codex, and Cursor, and offers codebase scans with AI triage, one-click fix PRs, scheduled scans, an AI wiki with MCP support, and integrations with Jira, Linear, Asana, Notion, and Confluence. It works with GitHub and offers a desktop app for macOS, Windows, and Linux.
cubic is language-agnostic and supports popular languages including JavaScript, TypeScript, Python, Go, Ruby, Java, and C#. Packaging is per-developer with a free Starter plan limited to 20 PR reviews per month, paid Team, Pro, and Max editions with 7-day trials, and a custom Enterprise tier with SSO/SAML. Public repositories are free, and paid plans are metered by reviewed lines per developer per month.
