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 😍

at-tracker.opensci.devAT Proto Collection TrackerDiscover AT Protocol activity from the bottom up — live record counts by collection type from the Jetstream firehose, grouped by namespace.

Is there any api here? Or a way to dump the data without scraping?

not yet but easy to add simple listing & details-by-namespace endpoints 👍 Any use cases in mind / other query patterns that would be useful?

The at-tracker app here watches for new collections and just maintains an index of namespaces/domains that it finds -- it built a massive queue to start with but has now caught up and I guess it'll take a bit of time before is sees everything out there at least once

ideas of things to change or add here to make this more useful are welcome, and it's pretty cool that it's running sustainibly (it looks like anyway at-tracker.opensci.dev/about) on a tiny hetzner instance

Neat, looks pretty similar to @bad-example.com's ufos.microcosm.blue
