## Bluesky Protocol Services Introduced

Bluesky announced a new brand and website to manage the infrastructure running on the AT Protocol network. This infrastructure, including Jetstream instances, relays, and Bluesky API endpoints, has been made more accessible to developers. The new documentation clarifies service contracts and provides a clean path for future releases. Replacing the old docs.bsky.app site, this new platform promises a better experience for developers.

## History Support with Jetstream v2

Jetstream v2 offers access to existing records on the network. In the previous version, accessing network history required local backfilling. The new version maintains a compressed archive of the entire network, and the Network Replay feature allows seamless transition from any point in the past to the live stream. This feature is stateless on the server and requires no client-side setup.

## Advanced Server-Side Slicing

Jetstream v2 enables more sophisticated server-side slicing. Users can spin up an app, run analyses over a month of posts, or recover from downtime—all using the same JSON structure as the live tail. Serving these archives is bandwidth-intensive, so an API token is now required for archive requests. The live tail remains open and unauthenticated.

## New Jetstream SDKs

Jetstream, being plain JSON, doesn’t require an SDK. However, new Jetstream SDKs for TypeScript and Go have been introduced to handle common tasks like reconnecting, deduplication, and cursor management. The TypeScript SDK is available via npm, while the Go SDK is part of the Jetstream project, offering easier integration for developers.

## TypeScript SDK Revamped

The Bluesky TypeScript SDK has been rebuilt on @atproto/lex, meaning legacy code paths for Bluesky-specific helpers are no longer maintained. The lexicon toolchain provides a fully typed end-to-end experience, from the protocol layer up through app records. All TypeScript examples on the new site are written against this SDK, marking a significant reduction in technical debt.

## HTTP Reference Updated

The HTTP reference has been updated and separated from https://docs.bsky.app. The new network.bsky.jetstream.* methods supporting Replay are now browsable with full request and response schemas. Jetstream’s WebSocket endpoints are also documented, consolidating the entire Jetstream v2 surface in one place for a more consistent developer experience.

## New Features Now Live

The new website, Jetstream v2 instances, SDK preview, and updated HTTP reference are now live. Beginners can start with 'How It Works,' a visual guide explaining how records, lexicons, and the firehose fit together. Developers building against Bluesky’s data model will find all Bluesky API guides freshly rewritten. Those who build on Replay are encouraged to share their projects.

## Significance for Developer Community

Bluesky Protocol Services makes open network infrastructure more accessible and manageable. Jetstream v2 and new SDKs provide developers with powerful tools, while improved documentation reduces the learning curve. These updates support Bluesky’s vision of an open network and foster community growth. The new features offer significant opportunities, especially in data analysis and app development.
