Codacy grades the code.
Hyrax architects the codebase.
Codacy aggregates linters, coverage and duplication into a quality dashboard, which is a clear way to track standards across many repositories. Hyrax reasons about the codebase instead of grading it, and delivers changes verified against the project test suite.
- 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.
Verified end to end, with no Codacy handoff
What changes when Hyrax runs above the tools.
Six domains, not one
Codacy covers its own scanning domain well. Hyrax evaluates security, correctness, maintainability, performance, architecture and operations together.
Verified against the project tests
A rules engine confirms a change satisfies its own rules. Hyrax runs the project test suite and build, so a change is proven against the real system.
Context that compounds
The map of the codebase lives in the repository and strengthens with every merge, so the next decision starts from everything learned before it.
How Hyrax and Codacy make decisions.
| Decision criteria | Codacy | Hyrax |
|---|---|---|
| Unit of work | The commit and the pull request, measured against rules. | The whole repository, audited continuously across six domains. |
| Codebase context | Static analysis per project, with coverage and duplication metrics. | A durable map committed to the repository as HYRAX.md and .hyrax/discovery, so it strengthens as the codebase changes. |
| Output type | Issues, coverage reports and quality gates. | Verified pull requests, plus issues ranked by severity and effort. |
| Verification | A change is validated against Codacy rules, not the project test suite. | Baseline tests, build, lint and a second reviewer agent run against the project itself before a pull request opens. |
| Human control | The team resolves issues and merges. | A human approves and merges every pull request. Hyrax never merges on its own. |
| Delivery surface | Git providers, CI and the Codacy dashboard. | GitHub pull requests, with issues and posture in the Hyrax console. |
| Pricing model | Free for open source, then per seat from around $18 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. |

- 02Issues arrive as a list to triage, with severity attached.
- 03The team decides what is worth resolving, makes the edits, and merges.
- 01Maps the codebase and keeps the map in the repository
- 02Applies architectural judgment across six domains
- 03Opens a verified pull request that a human merges
GitHub-native. Human-controlled. Verified before merge. No training on customer code.
From install to the first verified pull request.
Install the GitHub App
Grant read access to the repositories in scope. No card is required to start.
Hyrax maps the repository
Discovery writes HYRAX.md and .hyrax/discovery into the repository, so humans and AI tools read the same context.
Review the first pull request
Approved upgrades arrive as verified pull requests. A human merges every one.
Both tools solve real problems.
Choose Codacy if
The need is a consistent quality score and coverage reporting across a large number of repositories, in one dashboard. Codacy is a straightforward way to get it.
Choose Hyrax if
A grade describes the problem without moving it. Hyrax ranks issues by severity and effort, then delivers verified pull requests that change the number.
Free for open source, then per seat.

Questions about Codacy and Hyrax.
Does Hyrax work alongside Codacy?
Yes, and most teams run both. Codacy 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 Codacy setup has to change.
What does Hyrax change in the repository?
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.
How does pricing work?
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.
What happens after signup?
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 issues ranked by severity and effort. The first verified pull requests follow once an audit is approved.
