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.

Unless I am blind or my search-fu is hugely failing me, I cannot for the life of me find any information on the recommended/minimum specs to self-host the matrix backend services. I'm trying to spin up a VM just to play around with it and see if I like it. Specifically, I'm looking at Synapse or Continuwuity. Any advice?

Looking for vCPUs, memory, storage.

Most of the requirements are going to be for the database, and that depends on:

  1. How many active users you expect
  2. How many large rooms you or your users join

I left many of the large Matrix spaces I was in, and mine is now mostly just 1:1 chats or a group chat with a handful of friends. Given that low-usage case, I can run my server on a Pi 3 with 4 GB of RAM quite comfortably. I don't do that in practice, but I do have that setup as a backup server - it periodically syncs the database from my main server - and works fine. The bottleneck there, really, is the SD card storage since I didn't want an external SSD hanging off of it.

Even when I was active in several large Matrix spaces/rooms, a USFF Optiplex with a quad core i5, 8 GB of RAM, and a 500GB SSD was more than enough to run it comfortably alongside some other services like LibreTranslate.
