Hyrax

Hyrax is a hosted repository analysis tool for engineering teams using GitHub and AI coding assistants. It discovers repository architecture and conventions, audits code, reviews pull requests and offers fixes as pull requests for a developer to review and merge. It is a candidate for teams that want codebase-wide checks alongside individual coding sessions, not a replacement for engineering review.

Repository context and audits

Current documentation says discovery context is stored in the Hyrax workspace and served to coding tools over MCP. Nothing is committed into the repository by discovery. That differs from older descriptions of HYRAX.md and an in-repository discovery directory, which we have removed from this listing. Findings identify problems, priorities and file locations. The public sample audit shows a dashboard, finding list and proposed fix controls on a sample repository.

Fixes and human review

Hyrax describes generating a branch and pull request for selected fixes, checking its work before submission and leaving the merge to your team. Automatic PR review is enabled by default for connected repositories and can be turned off per repo. Generated changes still need tests and review against your system’s requirements. The sample app demonstrates the workflow, not the accuracy or coverage of a real audit on our own repository.

Connections and privacy

GitHub provides repository access; documented integrations include Linear and MCP-capable coding tools. Official pricing says AI inference runs on AWS Bedrock. Security documentation says source clones are removed at job end, staged copies expire within seven days as a backstop, and finding metadata and job history remain with the workspace. Backups and deletion records have separate retention periods. Provider data terms still matter: do not treat hosted processing as a blanket no-training or no-retention guarantee.

Pricing

Free workspaces get the full product with up to 100 free PR reviews a month, a one-time $30 starter credit and $10 of monthly credit. Paid costs $30 per seat per month and includes $30 of monthly usage credit per seat. Monthly credit expires at period end; starter credit does not. Workflow costs vary by repository and job, so the seat price is not a promise of unlimited audits. Paid overage is opt-in and can be capped. With overage off, new cost-bearing work stops when available credit is exhausted.

Editorial assessment

Hyrax’s useful combination is repository discovery, prioritized findings, reviewed fix PRs and shared context for coding assistants. The free path gives teams a way to inspect real findings without committing to paid seats. Hosted repository access and variable job costs are the main tradeoffs. Start with a representative repository and evaluate finding relevance, generated diffs and usage before adopting it as a routine gate.

Our 3.7/5 editorial rating is based on the official product, current documentation, pricing, legal pages and public read-only sample app checked October 10, 2026. We did not connect a repository, run an audit or measure finding accuracy, fix quality or time savings.
