Depends what you’re looking for. “Nostr” for each user is just the relays they’re connected to. Global feed shows the real time activity from those relays. If you mean something more like aggregated statistics then there are some sites like Nostr.band that show stats from a wide range of relays. But I’m not sure if they’re real time.

Run a relay :)

Otherwise i'm working on a live version of nostr-to-grouce...

or go to https://nostr.band/stats
