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.

We require applications, and most applications we get are extremely low effort and we don't approve them. If you have open registrations you'll be doing a lot of moderation for spam.

Run the software that scans images for CSAM. It's not perfect but it's something. If your instance freely hosts whatever without any oversight, word will spread and all of a sudden you're hosting all sorts of bad stuff. It's not technically illegal if you don't know about it, but I personally don't want anything to do with that.

I would just turn off media uploads entirely. It's not worth the risk or disk space.

I would just turn off media uploads entirely.

Do you mean also disabling thumbnails? IIUC, pict-rs handles all thumbnail generation [1]. The reason I point this out is that simply disabling image uploads won't itself stop the generation of thumbnails [2]. There's also the question of storing/caching images that come from federated servers.

      Pict-rs is a service which does image processing. It handles user-uploaded images as well as downloading thumbnails for external images.
