This server is currently self-hosted because that is the cheapest option for me right now. It's made out of scrap parts but does the job just fine!
Minecraft - A fairly optimized minecraft server, its mainly just a private server for me and my friends. I also host modded servers on occasion, I've hosted too many modpacks to even remember.
Etherpad - I also host an etherpad, mainly for myself to move away from google docs for simple notes.
Matrix - I also host a matrix-synapse server as a way to move the people I talk to off discord. I also suddenly realized it's a great way to drop a public contact thats not email. I think the whole decentralized idea is super cool.
Git server - My personal git server is on here and it's so cool. I use stagit (suckless uses it and it looks real minimalist) as my web frontend and it looks super super good!
Lufi - This is a E2EE file sharing service. Really cool so I decided to self-host it! Is password protected but if you want to use it feel free to contact me.
Pleroma - Pleroma is a federated twitter alternative. Wanted to host it because it looks real cool and I can keep up with some people. Hard to find cool people on it, at least for me (someone who doesn't use social media much). Though it's good for my friends and others that would be using twitter or other evil socials: it gives them a reason to switch! Also I may use it more because I really like it so far.
