I’ve been working on a small Fediverse project called "The Hitchhiker’s Guide to the Fediverse". It started as a simple directory of Fediverse instances, but I’ve been gradually turning it into something more useful: - discovering new instances through federation peers - filtering suspicious/spammy hosts - monitoring known instances over time - automatically hiding servers that stay offline - bringing them back if they recover - keeping the whole thing updated with GitHub Actions The monitored set is already around 27,000 instances, so I also had to rethink the collector to use bounded concurrency and checkpointing instead of checking everything one by one. Still very much a work in progress, but it’s been a fun way to learn more about how the Fediverse actually behaves in the wild. https://github.com/thanksstevenkim/the-hitchhikers-guide-to-the-fediverse #Fediverse #ActivityPub #Mastodon #OpenSource #SelfHosting
