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.
Use-case fit
What job the tool is actually built for, and where it stops.
Upgrade execution depth
Whether it suggests, commits, or opens a verified pull request.
Validation method
What a proposed change is checked against before it reaches you.
Pricing transparency
How billing scales, and the gotchas that show up at renewal.
Code review
SonarQube
SAST + quality gates
Hyrax
Autonomous code review + resolve
Verdict: SonarQube 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 and validation
SonarQube
AI CodeFix suggests; Remediation Agent opens upgrade PRs, developer-triggered, validates against Sonar's own engine Validated against sonar's own engine, not your tests.
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: whole-repo vs PR-scoped
SonarQube
Rules-based static analysis, quality gates. Languages: ~30.
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 model
SonarQube
Cloud Teams ~$32/mo, per-LOC; Enterprise scales to $20K+/yr
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.

Where Hyrax fits
SonarQube are good at issue issues and pointing them out. Hyrax closes the loop: it audits the whole repository, writes the change in your conventions, runs your own test suite, and opens a pull request you review and merge.
