Snikket is easy to host in a docker container. You would have your own internet messenger for friends and family. Snikket is based on the xmpp protocol thats been around for 20 years, is tried and tested and very lightweight and does take very few resources on your server. things like Nintendo's messenger and WhatsApp are xmpp based).

I’m looking to get started with self hosting too. Could you share the links you used to get yourself set up?

I've been going down the slef hosting rabbit hole recently.

First, Home Assistant is worth doing - you've not got a smart home yet but this is the easy way to get one going. So worth it. You can buy a few cheap WiFi plugs, and plug in devices like lights or stuff you don't want on stand by and you have the start of a smart home. A smart thermostat and smart radiator valves are surprisingly easy to set up if you want to save some money and keep your home efficient - a bit more of an investment but worth it if you find you like the ease and power of WiFi plugs.

I also recommend Pihole - it's an ad blocker for your entire network. You can run it on Docker on x86 machines - you just point your router to use it as the DNS and it then filters all requests for you. It's really improved my experience on all my devices.

Next, Paperless NGX - scan your documents and paperless NGX will OCR read them to make them searchable and keep them in a database for you. You can use it to go paperless. Just make sure to sort our a backup.

Joplin is quite a good note taking app which you can self host to sync your devices and keep your data secure.

Syncthing is fantastic for syncing files between devices. I sync my main PC and living room theatre PC, plus in my case my Raspberry Pi as an always on broker and local backup.

Home Assistant? Maybe a homepage like Heimdall or some other dashboard? Maybe Uptime Kuma to notify you when your services go down? Definately a pihole or adguard home. Biggest quality of life improvement. It's the biggest thing my wife notices and approves of. She audibly groans in disgust when she leaves the LAN on her cellphone and sees all the ads and garbage that had previously been blocked. My pihole dashboard show 70% of the requests are blocked on my LAN. And everything works great.

Syncthing for files syncing, to replace stuff like OneDrive, Dropbox etc.

I use to sync files between my NAS, laptop, Steam Deck and phone, each with different dirs based on what I need synced there.

Why Radicale when you have a caldav-capable calendar in NC?

I host a number of alternate frontends. Alexandrite for Lemmy, Redlib for Reddit, Invidious for Youtube. And then I have the Privacy Redirect extension make any links to Reddit or Youtube go to my local.

Straying away from utilities, games are always fun to host. I got started with self hosting by hosting a minecraft server, but there are plenty of options.

If you're just looking for something to chew up CPU cycles and don't know what to host, consider something like BOINC where you're "self-hosting" (extremely loose term) scientific research, like cancer, new drugs, etc.

Karakeep is fantastic, I know you mentioned it already, but I just wanted to shout it out. The AI tagging is a little gimmicky and pointless, but it's super nice to have a really searchable, automatically organized bookmark manager.

I look at what services I use and see if I can replace any of them w/ a self-hosted solution. Rinse and repeat.

Looking for more stuff to host will just overcomplicate things. I instead try to look for ways to consolidate services down.

If you have a car Lubelogger is a solid maintenance tracker.
