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
Snyk
Developer security platform
Hyrax
Autonomous code review + resolve
Verdict: Snyk 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
Snyk
Auto-resolve PRs for dependency upgrades; SAST changes single-issue, scanner-validated Validated against its own scanner, 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
Snyk
SAST, SCA, container, IaC scanning. 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 model
Snyk
Per developer; low-seat caps push to Enterprise
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.
Pros and cons
Snyk
- Broad security coverage
- Strong dependency monitoring
- Container and IaC scanning
- Detection-led, remediation is limited
- Security-only, not code quality
- Changes validated against scanner, not your build
Hyrax
- Validates changes against your tests before any PR
- Whole-repo, all code, every commit, not only AI-written
- Credits meter usage, no feature walls
- 13-step verification, never auto-merges
- New entrant to the category
- US-only at launch
- No standalone IDE assistant
Where Hyrax fits
Snyk 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.
