Founding Story
Pullfrog was created by Colin McDonnell, best known as the author of the TypeScript schema validation library Zod (42,000+ GitHub stars) and the original author of tRPC. After graduating college in 2016, McDonnell spent years indie hacking, went through Y Combinator as a solo founder (EHR startup, YC W19), and worked at EdgeDB/Gel and Bun. He launched an initial preview of Pullfrog in late 2025 and officially announced the beta on May 12, 2026, positioning it as an open-source CodeRabbit alternative that runs entirely in GitHub Actions instead of as a hosted SaaS.
