Cubic
What it is
Cubic provides AI code reviews for pull requests and scans codebases for bugs and security issues. It checks proposed changes against the full codebase and team rules, including effects elsewhere in a project. The service learns from senior developers’ previous review comments and team feedback. It can auto-approve low-risk pull requests, assign merge confidence scores from 1 to 5, and let coding agents fix findings. Cubic supports GitHub and GitHub Enterprise Cloud, but not GitHub Enterprise Server, GitLab, or Bitbucket. It describes itself as language-agnostic and lists JavaScript, TypeScript, Python, Go, Ruby, Java, and C#. Reviews run in isolated containers; the service says data uses TLS 1.2 or later in transit and AES-256 at rest, and AI providers cannot train on customer code. Starter Free allows 20 monthly reviews for public repositories. Team is $30 a month billed yearly per developer, while Pro is $79 and Max is $160 on the same term.
