m5l.eu 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.
Live location is very sensitive data, but #selfhosting the server with TLS and basic authentication gives me more privacy than the big tech cloud. And it only needed reading a bit of MDN and making a basic #Docker image based on #NodeJS
