Bluesky launches Protocol Services with Jetstream v2 network replay
Bluesky Protocol Services
Bluesky has launched Bluesky Protocol Services, a new brand and website for the public infrastructure it operates on the AT Protocol. The headline feature is Jetstream v2, which adds Network Replay: developers can now backfill historical data from a compressed archive via HTTP, then seamlessly switch to the live WebSocket stream. This stateless replay requires an API token for archive requests, while the live tail remains open. The company also released new TypeScript and Go SDKs for Jetstream, rebuilt the Bluesky TypeScript SDK on @atproto/lex, and updated the HTTP reference. All infrastructure is open source and self-hostable.
Replay is stateless on the server, with no per-consumer cursor, no subscription to register, and nothing to stage on the client.
