Rigorous code review, funded for open source.

Eligible public projects receive evidence-backed Ultra reviews without a card. Start with five reviews per project each month, or tell us why a larger grant would help your maintainers.

What your project receives.

Free does not mean a reduced product path. The programme changes who covers the review cost; it does not turn the result into a lightweight lint pass.

The complete review path
Each granted review follows the same Ultra path: repository context, deterministic checks, model-assisted investigation, and evidence tied to the exact pull-request head.
Capacity that refreshes monthly
The baseline grant is five Ultra reviews per approved project every UTC calendar month. You can request a higher allowance when the project needs it.
Built for public maintainers
We verify the public repository, its licence, and your maintainer access. The grant is attached to the approved project, not to a personal trial.
Maintainers stay in control
Review output is advisory. Repository owners decide what is published, accepted, or merged, and can disconnect the GitHub App at any time.

From application to first review.

The form asks for enough information to allocate real review capacity responsibly. Submitting it does not install the app or start a review.

  1. 01

    Tell us about the project

    Sign in, select the public repository, and request the monthly review allowance that would be useful.

  2. 02

    We verify eligibility

    We confirm the repository is public, actively maintained, appropriately licensed, and that you can represent it.

  3. 03

    Connect and review

    After approval, connect the selected repository and use the granted Ultra reviews on pull requests.

Open-source grants and Launch are separate.

Use the route that matches the repository and the capacity you need. Connecting a public repository does not automatically add both allowances.
