Explore the network
Bluesky operates public infrastructure for AT Protocol as open services anyone can build on.
Bluesky runs on a public social network of users' own individual data repositories. This is the AT Protocol. Anyone can build on the AT Protocol with the data already on the network.

Many AT Protocol services and infrastructure are provided by Bluesky. They sit at different layers, from a jetstream of everything happening right now, down to the cryptographically verifiable raw firehose; but they all share the same open data and open access. These docs describe the public protocol services and show how to build on them, or host your own.
Start with Jetstream
Jetstream is the fastest way to stream and query real network data.
On AT Protocol you can access all the public data on Bluesky; posts, likes, and the full Bluesky social graph. But you can also tap into other kinds of data, like shared code samples and CI patterns, a growing index of blog posts across the web, and local community groups.
Jetstream provides just the slice of the network you want as plain JSON over a WebSocket. The stream below is the live network, right now:
The stream above uses the same connection you'll write in the Jetstream docs: a few lines to consume the network live or replay it from history.

Filtered, decoded JSON over one WebSocket. Live, historical, or both. The place to start.
Relay
The full firehose in its raw, cryptographically verifiable form — every record, binary-encoded.
HTTP Reference
Bluesky app endpoints: profiles, posts, threads, feeds, and interactions over HTTP.
Bluesky API
Bluesky API docs.
Use a Relay when you need every record with no filtering, or the proofs to verify repository state yourself. Use the Bluesky API when you're building against the Bluesky app's data model directly. See API hosts and auth for endpoints and authentication, or browse the full HTTP reference.
Building on the Bluesky app
If you're looking to develop for the Bluesky app — making your first post, reading feeds, working with profiles and interactions — the Bluesky API guides walk through the API step by step.
