'''Jetstream''' is an unauthenticated events streaming service developed by [[Bluesky Social]] starting in October 2024.<ref>[https://docs.bsky.app/blog/jetstream "Introducing Jetstream"]. Bluesky. Retrieved March 12, 2025.</ref> It is an alternative to the global [[firehose]] to offer clients a more convenient way to synchronize record changes from different services in the AT Protocol. The primary audience of Jetstream is developers of services like [[Feed generator|feed generators]], who do not need to establish an exact replica of the AT Protocol network for their service to function. Jetstream consumes and transforms the [[wikipedia:CBOR|CBOR]]-encoded [[wikipedia:Merkle_tree|MST]] blocks from the global firehose into [[wikipedia:JSON|JSON]]. It also allows clients to preselect a subset of record updates to receive, filtering the firehose by [[Collection|collections]], [[Actor|actors]], and the size of record update. Similar to the firehose, Bluesky Social provides public Jetstream instances at <code>bsky.network</code>. == References == <references /> == External links == # [https://github.com/bluesky-social/jetstream GitHub repository]
