Pulsar 💫 #

A tool for measuring the coverage of Bluesky/ATProto relays.

What does it do #

Pulsar monitors ATProto relays to compare how many accounts' data each one includes. Since connecting to 10-20 relays in parallel generates very big network traffic, this is meant to be used in relatively short "bursts" by either running it manually until it's stopped with Ctrl+C, or running it periodically from cron e.g. for an hour every day.
