Buyer Guide

Baz vs Hyrax

Baz and Hyrax come up in the same conversations. They get lumped together as "AI code tools," but they solve different parts of the workflow and stop at different points.

This is a straight comparison: what each tool actually does, how far it takes a change, how it validates that change, and what it costs. The body stays neutral. Where Hyrax fits is covered at the end, clearly marked.

Methodology

Evaluation criteria

Each tool is measured on the same four criteria, focused on what happens to an issue after it is detected, not just how many issues it produces.

01

Use-case fit

What job the tool is actually built for, and where it stops.

02

Upgrade execution depth

Whether it suggests, commits, or opens a verified pull request.

03

Validation method

What a proposed change is checked against before it reaches you.

04

Pricing transparency

How billing scales, and the gotchas that show up at renewal.

Code review

Code review

Baz

Autonomous review + resolve agents

Hyrax

Autonomous code review + resolve

Verdict: Baz are solid at surfacing issues in a pull request. Hyrax reviews the same code, then takes it further by opening a tested change.

Autonomous change

Autonomous change and validation

Baz

Yes, but PR/ticket-scoped, not codebase-wide Validated against limited.

Hyrax

Yes. Writes the change in your conventions, runs YOUR tests, 13-step verification, opens a PR, closes the Linear ticket, never auto-merges Validated against your own test suite.

Verdict: This is the clearest split. Most of the field stops at suggestions or comments. Hyrax writes the change, runs your tests, and opens the PR.

Coverage

Coverage: whole-repo vs PR-scoped

Baz

PR- and ticket-scoped agents, reactive. Languages: many.

Hyrax

Whole-repo audit across 6 domains, opens tested PRs you merge. Languages: 18.

Verdict: PR-scoped tools only see what is in the diff. Hyrax audits the whole repository across six domains, so it catches issues outside the current change.

Pricing

Pricing model

Baz

$30/dev/mo; Free = 50 PR reviews

Hyrax

Free with full access and starter credits / Paid $30/user/mo. Each paid user gets $30/mo of credits.

Verdict: Most rivals bill per seat or per line of code, which scales with team size. Hyrax uses flat plans with usage credits and no per-seat fee.
