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.

From North America, and I’m going on vacation in china for a few weeks. I wonder if anyone knows if I’ll be able to access any of my self-hosted services over zerotier while I’m abroad?

Edit: To be specific, I’m hoping to ssh into my machine over zerotier in case I need to fix something and back up some photos to my home NAS via rsync or something

As another user posted, how strict the firewall is depends on where you are (and if there are any special events). I heard that Wireguard doesn't work because of deep packet inspeciton, but I was able to use Tailscale to my home network without problems when I was there last year. I also set up a xray vless-reality proxy on a VPS and Outline servers on Google cloud and those worked too.

But the easiest method is to buy an HK eSIM for roaming (I used 3HK). I bought a month of LetsVPN but they booted me from the service for some random reason, so I changed to Mullvad which also worked too.
