A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

What things do you self host (or know about) that are fun/interesting/useful to you? I'm thinking of setting up a home server and am looking for things that would be useful or fun for me to run on it. I want to host things that are useful/fun, but not a project itself (I've got enough projects), if that makes sense.

Most of the lists I see online are mostly lists of technical projects like docker, kubernetes, grafana, nginx, etc. I see these as infrastructure rather than the interesting project itself. ETA: the infra is important, but not "interesting" in this context as I deal with infra at my day job.

Examples of the type of service I'm looking at: a media server, photos app (to replace Google Photos), game servers, recipe management, home automation... What other things do you know about that are fun/interesting/useful?

Edit: thank you everyone for your awesome responses!

Home Assistant.

If you want smart devices but not the data collection that goes with it, then Home Assistant is your friend. Just be forewarned that it is a seriously deep rabbit hole.

Hello from the rabbit hole. I haven't seen the light of day in years.

I barely know what food, water or sleep is anymore. But hey! I can turn my lights off and have them come on when sunset occurs. Or they track when I leave my apartment complex property with my cellphone so I don't waste power and there's no 3rd party corpo breathing down my shoulder.

You have to show me that truck, how you got out of your apartment while remaining in the hole. That's some Goyo Satori stuff right there.

I spun it up it up in may to fool around. Today I opened a brand new air purifier and imeaditley disassembled it to flash ESPHome firmware on it. It never once ran stock.

I used them for Christmas lights with that sundown condition (+just a time trigger for off at night).

Also came in handy for a light switch that was unfortunately on the wrong side from a table, now its just uses a motion sensor when someone walks to the kitchen and tells a third reality smart switch (screws on top of regular switch, so it works with any light type (e.g. fluorescent)) and is renter friendly.

Bonus points for no lag at all compared to crappy cloud dependent garbage and no need for apps for each device manufacturer. Just look if it is home assistant compatible and no cloud before buying devices since it us a lot harder or impossible in some cases to de-cloud them later.

Edit: plus same motion sensor concept to link several lights on the living room (those are just dimmable smart lights on table and floor lamps). Makes the place look cozy and feel well illuminated vs the usual single light with a wall switch. Aquara Wireless clicker to toggle between dim percentages. Its awesome (third reality or other home assistant friendly brand would work, I just already had this one).
