Solutions
Hyrax discovers services, dependencies, boundaries, conventions, risks, and architecture across your repository.
HYRAX.md and .hyrax/discovery keep the map inside your repo.
The map lives in your repo, so humans and AI tools read the same context.
Six specialized agents evaluate security, correctness, maintainability, performance, architecture, and operations.
Hyrax turns the highest-leverage work into verified pull requests your team can review and merge.
Every merge updates the context, so the next change starts smarter than the last.
AI tools increased output. Hyrax gives that output architecture, context, and control.
Built for teams using Cursor, Copilot, Claude Code, Codex, and Devin.
Velocity got solved. Architecture did not.
Velocity vs. excellence
Autocomplete
Sync agents
Async agents
AI made writing code 17x faster while shipping barely moved. Speed alone doesn't build better products. The advantage now belongs to teams that turn velocity into excellence.

Connect GitHub and Hyrax builds the map on its first run.
HYRAX.md + .hyrax/discovery · context for human and AI contributors
Security, correctness, maintainability, performance, architecture, and operations evaluate every repo from shared context.
Specialized judgment, prioritized by impact
Review what matters, dismiss what does not, and approve the improvements worth shipping.
Human control · stable HYRAX-N refs · approve, dismiss or request changes
Hyrax turns approved improvements into verified GitHub pull requests your team can review and merge.
Isolated worktree. Your tests. Your build. Human approval.
The codebase map updates as your repository changes, so the next run starts with better context.
Context compounds. Drift decreases.
Every approved improvement runs in an isolated worktree with your tests, build, and checks before it becomes a pull request.
Interactive demo of a Hyrax pull request review. Three changed files are open as tabs — env.ts, .env.example and env.test.ts — each showing its diff and a note on which existing repository convention the edit follows. Files can be switched, closed and restored, and the change can be approved or sent back for changes.
src/lib/env.ts

Matches existing convention
Uses the repo's existing requireEnv helper from src/lib/env.ts rather than reading process.env inline, matching the 23 other call sites.
Install the GitHub App and Hyrax writes the first codebase map into your repo. No CI rewrite. No new workflow to learn.
Install once. Improvements, PRs, issues and checks stay in GitHub.
Trigger workflows from Linear or API.
Improvement work connects to tickets automatically.
Human and AI contributors work from shared codebase context.
Discovery artifacts published to the storefront-web repository. A file rail lists HYRAX.md and 4 reference documents under .hyrax/discovery; the reading pane shows HYRAX.md.

Before claiming a change is complete, the commands below must pass.

Order is fast to slow; run earlier rows first so cheap checks fail before expensive ones.

FAQ
Hyrax helps engineering teams understand what's happening across their codebase, identify what matters, and turn improvements 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 improvements, and PR reviews; there are no feature walls. Overage is opt-in with budget caps.
The 13-step verification gate checks an improvement 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.
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.
