Claude Code review alternative for AI-native engineering teams
Claude Code reviews changes.
Hyrax architects the codebase.
Claude Code can review pull requests from a GitHub Action, and it is flexible because the team writes the workflow. Hyrax is a product rather than a prompt: a fixed six-domain audit and a 13-step verification that runs the same way every time.
Hyrax audits roughly 400 of its own repositories.
Free plan: full access, up to 100 PR reviews a month, a $30 starter credit, and $10/month ongoing.

Why teams switch
What changes when Hyrax runs above the tools.
The codebase, not the diff
Claude Code review sees the change in front of it. Hyrax audits the whole repository, so problems that no single pull request touches still surface.
Verified before it arrives
Every fix runs the project baseline tests, build and lint, and passes a second reviewer agent, before the pull request exists.
Context that compounds
The map of the codebase lives in the repository and improves with every merge, so the next decision starts from everything learned before it.

FAQ
Questions about Claude Code review and Hyrax.
Yes, and most teams run both. Claude Code review keeps doing its job. Hyrax works at the level of the whole codebase, decides what is worth changing, and delivers verified pull requests. Nothing about the Claude Code review setup has to change.
Discovery writes HYRAX.md and a .hyrax/discovery directory, which document the architecture, conventions and risk areas of the codebase. Everything else arrives as a normal pull request on its own branch. Hyrax has no write access to the default branch.
The free plan includes full access, a $30 starter credit and $10/month of credits ongoing, with no card required. The paid plan is $30 per user per month, and each paid user gets $30/month of credits. Pull request reviews are included on every plan.
Installing the GitHub App and granting access to a repository takes a few minutes. Hyrax maps the codebase, then runs the first audit and returns findings ranked by severity and effort. The first verified pull requests follow once an audit is approved.
