Radicle is a peer-to-peer, local-first code collaboration stack using Git storage, cryptographic identities, and a custom gossip protocol – no central host.
Key Takeaways
Repos replicate across peers via Git data transfer; social artifacts (issues, patches, discussions) are stored as Git objects called Collaborative Objects (COBs).
Node communication uses NoiseXK; an HTTP daemon exposes JSON APIs, making the stack modular – CLI, Web, TUI, and Node are independently swappable.
Local-first design means full functionality offline; all data is public-key signed, giving verifiable authorship without a trusted third party.
v1.8.0 released March 2026; a March 2026 signed-references vulnerability was disclosed, patched, and published alongside the release.
Linux, macOS, and BSD only – no Windows support currently.
