Greptile alternative for AI-native engineering teams

Understanding is the start.
Hyrax ships verified fixes.

Greptile indexes the full repository and reviews pull requests with that context, which is a real advantage over diff-only reviewers. Hyrax takes the same starting point further: it keeps the map in the repository and turns findings into verified pull requests.

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.

Why teams switch

What changes when Hyrax runs above the tools.

The codebase, not the diff

Greptile sees the change in front of it. Hyrax audits the whole repository, so problems that no single pull request touches still surface.

Verified before it arrives

Every fix runs the project baseline tests, build and lint, and passes a second reviewer agent, before the pull request exists.

Context that compounds

The map of the codebase lives in the repository and improves with every merge, so the next decision starts from everything learned before it.

Comparison

How Hyrax and Greptile make decisions.

Decision criteria
Greptile
Hyrax
Unit of work
The pull request, reviewed with full repository context.
The whole repository, audited continuously across six domains.
Codebase context
Indexes the repository into a graph, refreshed as the code changes.
A durable map committed to the repository as HYRAX.md and .hyrax/discovery, so it improves as the codebase changes.
Output type
Review comments and severity-labelled findings on the diff.
Verified pull requests, plus findings ranked by severity and effort.
Verification
Comments are advisory. The team writes and tests the change.
Baseline tests, build, lint and a second reviewer agent run against the project itself before a pull request opens.
Human control
The team makes every change.
A human approves and merges every pull request. Hyrax never merges on its own.
Delivery surface
GitHub, GitLab and Bitbucket pull requests.
GitHub pull requests, with findings and posture in the Hyrax console.
Pricing model
Per seat, commonly around $30 per developer 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.

Greptile
  1. 01A pull request opens and Greptile reads the diff.
  2. 02Greptile returns comments, summaries and suggested changes.
  3. 03The team interprets the feedback, makes the edits, and merges.
Hyrax
  1. 01Maps the codebase and keeps the map in the repository
  2. 02Applies architectural judgment across six domains
  3. 03Opens a verified pull request that a human merges

Getting started

From install to the first verified pull request.

01

Install the GitHub App

Grant read access to the repositories in scope. No card is required to start.

02

Hyrax maps the repository

Discovery writes HYRAX.md and .hyrax/discovery into the repository, so humans and AI tools read the same context.

03

Review the first pull request

Approved improvements arrive as verified pull requests. A human merges every one.

The honest verdict

Both tools solve real problems.

Choose Greptile if

The goal is better review comments with real repository awareness, and the team is happy to do the fixing. Greptile is one of the strongest options for that.

Choose Hyrax if

Codebase understanding should produce work, not just commentary. Hyrax commits the map to the repository, audits beyond open pull requests, and returns fixes that already passed the project tests.

FAQ

Questions about Greptile and Hyrax.

Yes, and most teams run both. Greptile 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 Greptile setup has to change.

Context is where Hyrax starts rather than where it stops. The map is committed to the repository as HYRAX.md and .hyrax/discovery, so it persists and improves with every merge instead of being rebuilt per review. Hyrax then acts on it: findings across six domains, and fixes verified against the project baseline tests, build and lint before a pull request opens.

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.

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.

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 findings ranked by severity and effort. The first verified pull requests follow once an audit is approved.
