Graphite vs Hyrax

Graphite stacks and reviews PRs.
Hyrax fixes the code.

Graphite is a code review platform built around stacked pull requests, with an AI reviewer (Graphite Agent, formerly Diamond) posting inline comments on every PR. Reviews still hand the work back to developers. Hyrax audits the whole codebase, fixes issues, and ships PRs verified against the test suite.

The difference

Same surface area. Hyrax does the work.

Graphite
  • Stacked PR workflow with a CLI and merge queue
  • AI reviewer (Graphite Agent, formerly Diamond) posts inline comments on PRs
  • Comments hand the fix back to the developer
  • Per-seat pricing that scales with team size
Hyrax
  • Audits the entire codebase across six categories
  • 13-step verification with baseline tests before every fix
  • Creates a [Hyrax] PR and closes the ticket, you approve the merge
  • Usage-based pricing, compute credits included, no per-seat fees

The edge Graphite misses

A fix isn't done until it's verified.

Graphite stops at a suggestion or a scoped patch. Every Hyrax fix runs a 13-step verification before it can merge. Baseline tests are established first, the fix is applied, and the full pipeline confirms nothing else broke. Nothing ships on trust.

FAQ

Questions about switching from Graphite.

Yes. Graphite manages stacked PRs and reviews in the merge workflow. Hyrax audits the codebase and ships verified fixes. They cover different parts of the pipeline.

Graphite's AI reviewer (Graphite Agent, formerly Diamond) posts review comments on a PR, then a developer implements the change. Hyrax makes the change itself in an isolated worktree, runs the test suite and build, passes a reviewer agent, and creates a [Hyrax] PR you approve. Hyrax never merges for you.

No. Hyrax has no merge queue or stacking workflow. It works at the repository level (audit, fix, and governance), so it complements a review platform like Graphite rather than replacing it.

Stop reviewing. Start shipping.
