In their own words
Cubic
Cubic reviews pull requests with AI and scans codebases for bugs and security issues. It checks proposed changes against the wider codebase and team rules, including possible effects on other code, and learns from senior developers’ past comments and team feedback. The workflow can auto-approve low-risk pull requests, assign a merge confidence score from 1 to 5, and let coding agents fix findings. Cubic supports GitHub, including GitHub Enterprise Cloud; GitHub Enterprise Server, GitLab and Bitbucket are not supported yet. It describes itself as language-agnostic and lists JavaScript, TypeScript, Python, Go, Ruby, Java and C# among supported languages. Starter Free allows 20 reviews a month for public repositories. Team costs $30 a month billed yearly per developer; Pro is 79.00 USD and Max is $160 a month, also billed yearly per developer. For pull requests with more than 200 eligible files, Cubic selects up to 200 for review. Reviews pause after a team exceeds its line allowance unless an admin enables flex capacity at $20 per 10,000 extra lines.
