Today we're releasing the alpha version of Radicle. Radicle is a p2p code collaboration platform (think Github replacement). Issues, patches (like PRs) and optionally code are distributed via IPFS, without a centralized server, and with tooling that's meant to work directly from your terminal. There's a lot more info on the webpage .
Radicle is written in Haskell (minus the parts that are written in the Radicle language itself, though the language is implemented in Haskell), and open-source, which is why I thought to post here.
