Graphite alternative for AI-native engineering teams

Graphite reviews pull requests.
Hyrax architects the system.

Graphite is built around stacked pull requests, a merge queue and the Diamond reviewer, and that workflow is excellent for shipping small changes quickly. Hyrax sits above the pull request: it decides what the codebase needs and delivers verified work into whatever queue is in place.

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

Graphite 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.

Comparison

How Hyrax and Graphite make decisions.

Decision criteria
Graphite
Hyrax
Unit of work
The pull request, inside a stacked diff workflow.
The whole repository, audited continuously across six domains.
Codebase context
Reviews the diff with surrounding repository context.
A durable map committed to the repository as HYRAX.md and .hyrax/discovery, so it improves as the codebase changes.
Output type
Review comments from Diamond, plus merge queue automation.
Verified pull requests, plus findings ranked by severity and effort.
Verification
The merge queue runs CI. Review feedback is advisory.
Baseline tests, build, lint and a second reviewer agent run against the project itself before a pull request opens.
Human control
The team authors changes and controls the queue.
A human approves and merges every pull request. Hyrax never merges on its own.
Delivery surface
GitHub pull requests and the Graphite app.
GitHub pull requests, with findings and posture in the Hyrax console.
Pricing model
Free for small teams, then per seat from around $20 per user per month.
Free plan with a $30 starter credit and $10/month ongoing. Paid is $30 per user per month and each paid user gets $30/month of credits.

Workflow

Comments on a diff, or a verified pull request.

Graphite
  1. 01A pull request opens and Graphite reads the diff.
  2. 02Graphite returns comments, summaries and suggested changes.
  3. 03The team interprets the feedback, makes the edits, and merges.
Hyrax
  1. 01Maps the codebase and keeps the map in the repository
  2. 02Applies architectural judgment across six domains
  3. 03Opens a verified pull request that a human merges
GitHub-native
Human approval before merge
Verified pull requests
No training on customer code

Getting started

From install to the first verified pull request.

01

Install the GitHub App

Grant read access to the repositories in scope. No card is required to start.

02

Hyrax maps the repository

Discovery writes HYRAX.md and .hyrax/discovery into the repository, so humans and AI tools read the same context.

03

Review the first pull request

Approved improvements arrive as verified pull requests. A human merges every one.

The honest verdict

Both tools solve real problems.

Choose Graphite if

The bottleneck is review and merge throughput. Graphite fixes that directly with stacking and a merge queue, and Hyrax pull requests flow through it normally.

Choose Hyrax if

The bottleneck is knowing what to work on. Hyrax audits the repository, ranks findings, and produces verified pull requests that a stacked workflow can then move quickly.

Graphite pricing~$20/user/mo

FAQ

Questions about Graphite and Hyrax.

Yes, and most teams run both. Graphite 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 Graphite 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.
