Selfhosted

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.

I haven't watched the video yet, but it's generally not worth the hassle of setting up mutual TLS if you're already using a peer-to-peer VPN like Tailscale, as the VPN software is already doing mutual authentication.

Edit: A peer-to-peer VPN (or mesh VPN) is one where two systems that are connected to the VPN can directly communicate with each other, instead of needing to go through a central server as with something like OpenVPN. With Tailscale or Wireguard, the peers need each other's public keys to communicate.

The whole point of mTLS is that you dont need to use a VPN to achieve that same security.

I get that, but a lot of people are already using a VPN to access their self-hosted system.
