sdk.blue#

A list of libraries, frameworks and tools for the Bluesky API and AT Protocol. See the website here: https://sdk.blue.

Adding projects#

If you've created a library or SDK that you'd like to be listed on this page, please send a pull request.

Note: this is meant to be a curated list with only specific kinds of projects, not a list of all projects related to Bluesky and ATProto.

What kinds of projects I'm looking for:

• full SDKs for building things on ATProto in a given language
• targetted libraries for things like streaming from the firehose, making XRPC calls, building feeds, labellers etc.
• template repos for making e.g. labeller or feed projects using your library
• tools and helper services that can be used as part of a larger app

So generally repos that contain code that you could use to build your thing.

Additionally, I'm also including:

• independent implementations of things like PDS, relay, or Bluesky AppView
• example full non-Bluesky ATProto apps like Tangled or Leaflet

What I'm not looking for:

• client apps, user-facing tools, webapps, command-line tools etc.
• specific examples of bots, labellers, feeds etc.
