gyptazy.com is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Yes, and I find it quite good.
And to run it as a #FastCGI, you don't even need a VPS: a cheap shared hosting supporting #CGI will run #snac2 just fine! https://encrypted.tesio.it/2024/12/18/how-to-run-your-own-social-network.html
That's why I prefer it to gotosocial.
Also I try to avoid #Go as much as possible cause it's a #Google's thing.
Snac is written in a pretty readable (and a bit clever, sometimes) #C.
And if you know C even a little bit, it's really worth a read.
