I just started renting a basic VPS through Racknerd with the intent to use it as a reverse proxy to point friends to my game server instances running at home without exposing my public IP. I could not figure out how to get it to work so I gave up after days of trying and am now using playit.gg. I prepaid for a year of the VPS. What cool project should I try on it now?
You can set up a mail server. You can set up something like Nextcloud. You can set up a personal website, or just run a webserver and turn it into a place to dump files. You can set up something like Syncthing to facilitate sharing files between your devices. You can set up some types of Federated services, but in my experience Mastodon is too heavy for a baseline VPS. I needed to augment my instance with additional memory, CPUs, and an S3-compatible object storage provider for about 600GB of user media. Lemmy might work, but I haven’t tried running it on a VPS on the open Internet yet.
Nextcloud ran like garbage on my server that has better hardware than the VPS. I love the concept of it though and I would really like if the guy working on Memories could split that out from under NC.
I’ve found that GoToSocial and Calckey both use a lot less in resources than Mastodon does.
