Projects We Sponsor
A sample of the maintainers and projects we support today.
We're offering free Macroscope credits for qualified non-commercial open source projects.
Ship fewer bugs, speed through code reviews, track contributions, and get visibility into how your project is evolving — without any management overhead.
Eligibility Criteria for Free Access
Your project must use an open source license (MIT, Apache 2.0, GPL, etc.).
Your project must be used for non-commercial purposes and not sold or offered as a paid product or service.
We prioritize projects with an active developer community and a strong fit with the developers we build for.
Note: we reserve the right to limit usage based on reasonable use criteria.
Open source projects start on Budget and can switch any repository to Balanced or Precise whenever a change deserves it; Ultra stays on paid plans. Figures come from Macroscope's internal benchmark of thousands of real-world bugs, and the per-review pricing shown is our standard usage-based rate.

The pain points that Macroscope solves for traditional software companies are just as relevant — if not more painful — for open source communities:
AI code review is standard at every professional software company — but cost keeps it out of reach for open source.
Contributors spend time explaining their changes instead of writing code, just for reviewers to spend more time decoding them.
Maintainers need visibility into how their codebase is evolving and how contributors are engaging — but lack the tools and PMs that enterprises rely on.
