Hyrax

Architecture and remediation for AI-native teams: map the repo, find structural issues, and ship engineer-reviewed PRs.

What is Hyrax?

Hyrax positions itself as the architect beside your coding agents: it maps a repository (committing shared context like HYRAX.md), runs specialised agents across security, correctness, maintainability, performance, architecture and operations, then turns the highest-leverage findings into verified GitHub pull requests. The point is not another wall of review comments — it is continuous remediation that still leaves merge control with humans.

Before a PR reaches your team, Hyrax runs a long verification gate (isolated worktree, baseline and post-change tests, build, lint, diff-size limits, second-agent review, re-scan). If a required check fails, nothing ships. Inference runs in Hyrax's own AWS Bedrock account and the product states it does not train on customer code. Free access includes starter credit and modest ongoing credit; heavier use needs paid top-ups (check hyrax.dev for live numbers).

Editor rating ~4.3/5 in Coding. Best for AI-native teams that want structural cleanup and engineer-reviewed fix PRs; skip if you only need lightweight PR commentary or cannot grant repository access to an external remediator.

Best for:
  • Engineering teams drowning in AI-written code velocity
  • Closing security, correctness and architecture findings with verified PRs
  • Repos that want continuous remediation, not only PR comments
Not ideal for:
  • Teams that only want inline PR comments without autonomous fixes
  • Orgs that forbid any AI vendor touching the full repository
