I was thinking of hosting my own Mastodon Instance, but noticed that it's pretty big as in software, I'm looking for something a bit more light. I'm preferably looking for something that runs in docker, as I have that installed on my Linux book, Yes, I am using Linux as if I attempted to use Windows, MacOS I wouldn't have a great time.
Anyways, I was going to choose lemmy, but I think that's also heavy, not sure though!
I'm running Mastodon and yes it is quite a big software but it is fairly lightweight if you run a one person instance. The biggest advantage is that it's rock solid. I had zero problems running or upgrading it in the last um 5 years or something.
GoToSocial is designed for small / single user instances. There's more with similar goals like snac, seppo, pub, ktistec, tapir, shuttlecraft, activities.next, and microblog.pub, but I haven't really looked into them so I'm not sure on the status of each. There's a nice list of activitypub software at delightful fediverse apps if you want to look at more options.
