Blacksky Algorithms builds open-source, community-driven infrastructure for decentralized social media. Our mission is to empower communities with tools for safety, governance, and control over their online spaces.

We are developing a Rust-based implementation of the AT Protocol, including a high-performance relay, PDS, and custom algorithmic feeds. Our work supports individuals, researchers, and organizations focused on decentralized identity, trust & safety, and algorithmic transparency.

Check out our pinned repositories to see what we’re building. We welcome contributors—see our code of conduct and connect with us on Bluesky.
