A bottom-up tool for discovering activity across the AT Protocol network by watching live record types on the Jetstream firehose.
AT Proto Collection Tracker
Discover AT Protocol activity from the bottom up — live record counts by collection type from the Jetstream firehose, grouped by namespace.

Podium — open data search
Podium: a search engine for open data published on the AT Protocol — Matadisco datasets, Astrosky transient events, and more.
Introducing Tap: Repository Synchronization Made Simple | Bluesky
Just about every app built on AT needs data from a repository at some point. For many use cases – feed generators, labelers, bots – streaming live data through a Relay or Jetstream works well. But some applications need to go beyond what Jetstream was designed for, like tracking specific subsets of a repo, automatically backfilling a database when adding new repos to monitor, or even mirroring the entire Atmosphere.

firehose.stream — ATProto jetstreams
A lightweight, filterable JSON firehose of real-time ATProto events.

Firehose Viewer — ATProto Events
Real-time ATProto event stream from the Bluesky firehose via Jetstream
Opnshelf - Track What You Watch
Track what you watch and discover what others are watching. A personal media tracker built on the AT Protocol.
ATproto Command Center — Live Bluesky Firehose Dashboard
Real-time event velocity, hot collections, active accounts, and content signals — streamed from Jetstream and computed entirely in your browser.

Into the feed of Currents, an open Pinterest alternative built on AT Protocol - Matteo Marjanovic
In this article I describe how I built the first version of Currents' feed, an open Pinterest alternative on AT Protocol, and how its personalization slider works.

I'll be talking about @astrosky.eco's nebra package, which makes it super easy to post & stream scientific data on the AT Protocol - including the two month-long tech demo of doing this that we've been running with NASA's astronomical transients feed!

Friends from the Internet! This Thursday, join us for CID Congress — with a session dedicated to SCIENCE and what fun content-addressed data can do there! luma.com/ptrjn16w
built a thing at-tracker.opensci.dev - I wanted a way to do discovery on the #atproto network which was bottom up, and also was experimenting with building an indexer. Already found new cool things I didn't know about otherwise 😍
