Hyrax AI

Hyrax helps engineering teams understand what's happening across their codebase, identify what matters, and turn upgrades into production-ready changes. It maps your codebase and understands how your product is built, then six specialized agents evaluate security, correctness, maintainability, performance, architecture and operations. The highest-leverage work becomes verified pull requests in GitHub. An engineer reviews and merges every one.

Free gives every workspace full access to Hyrax, a $30 starter credit, $10/month ongoing credit, and up to 100 PR reviews a month for free, with no card required. Paid is $30 per user per month, and each paid user gets $30/month of credits. Credits meter usage across repository mapping, verified upgrades, and PR reviews; there are no feature walls. Overage is opt-in with budget caps.

When a developer wants deeper access: opening full summaries in Hyrax, asking Hyrax to resolve an issue, or running more workflows than the free credits cover. Each paid user gets $30/month of credits, and paid workspaces can opt in to overage with a budget cap they set.

The 13-step verification gate checks an upgrade before it reaches your team as a pull request. It covers isolated worktree execution, the tests it started with, the tests after the change, your build, lint and formatting, a size limit on the diff, a second review by an independent agent, a re-scan to confirm the original issue is gone, and CI. If a required check fails, the work stops and never becomes a PR.

AI tools write code. Hyrax architects the system that code enters. Assistants edit what you point them at, and their context starts empty every session. Hyrax holds the map of your codebase, and six specialized agents reason about security, correctness, maintainability, performance, architecture and operations before anything ships. Use both.

Scan reads the whole codebase first, so it understands your architecture and conventions, then looks for problems the way a reviewer would. It produces a ranked list of issues and easy wins, each with a plan for the change.

Every change ships as a pull request with the [Hyrax] prefix. PR Review reviews every opened pull request automatically against the codebase conventions, leaving comments that update as the code changes. It can block merge on must-resolve issues. You get up to 100 PR reviews a month for free.

Hyrax works across 19 languages: Python, TypeScript, JavaScript, Go, Rust, Swift, Ruby, Java, Kotlin, C#, C++, C, PHP, Scala, Dart, Elixir, Shell, Lua, and MDX. It works with the frameworks built on them: React, Next.js, Vue, Svelte, Angular, Node.js, Django, Rails, Spring, FastAPI, Express, React Native, and Flutter.

GitHub for source control. Linear for ticket management. Tickets are created on audit and closed automatically when changes merge.

Hyrax works through GitHub with human control, and it never merges on its own. Verification runs before a pull request reaches your team, and your engineers make the final call. All inference runs in the Hyrax AWS Bedrock account, and Hyrax does not train on customer code.
