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.

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
