Engineering write-ups from the people building Diffinery, an open-source git forge and GitHub Actions–compatible CI platform that runs on Cloudflare.
Notes from building Diffinery, an open-source (Apache-2.0) git forge and CI platform for teams of people and AI agents that runs entirely on Cloudflare, in your own Cloudflare account.
