Self-host Caddy on a VPS

A web server with automatic HTTPS by default.

Serve sites with a two-line config and certificates issued and renewed automatically.

Why self-host Caddy?

Caddy removes the TLS busywork entirely, making it the simplest way to serve self-hosted apps securely.

How to install Caddy

  1. 1

    Provision a VPS

    Choose a plan with room for your data as well as the app.

  2. 2

    Install the stack

    Install Single Go binary.

  3. 3

    Deploy the application

    Follow the project’s official install guide for your distribution.

  4. 4

    Enable HTTPS

    Serve it on your own domain behind a reverse proxy with a certificate.

  5. 5

    Back it up

    Schedule a database dump plus a copy of any uploaded files to an off-box location.

Practical tips

  • Give Caddy its own database user with rights only on its own schema.
  • Reverse-proxy Caddy and terminate TLS at the proxy so certificates are managed in one place.
  • Take a VPS snapshot before major upgrades so you can roll back cleanly.
  • Keep Caddy patched — most self-hosting incidents are unpatched software.
