(NB: I started with things that are active / well-known, trying to avoid stale repos. Definitely add items that are ongoing though, no matter how WIP. Maybe someone will be stoked to contrib!)
Welcome to the repository for the official Bluesky PDS (Personal Data Server). This repository includes container images and documentation designed to assist technical people with hosting a Bluesky PDS.
rsky (/ˈrɪski/) is intended to be a full implementation of AT Protocol in the Rust language. Most of the code here are general purpose implementations while some (like rsky-feedgen) are specific to the use cases of the Blacksky community.
Python implementation of Bluesky PDS and AT Protocol, including data repository, Merkle search tree, and XRPC methods.
Its not public yet, but will be once I get the mvp done (NB: this is real soon!)
A from-scratch atproto PDS implementation that dreams of becoming "production grade" software (it isn't, yet).
atompds is a proof of concept ATProto PDS (Personal Data Server) instance implementation written in C#. Most of the concepts have been manually translated from https://github.com/bluesky-social/atproto/tree/main/packages and should follow the same general structure.
