Headscale - An open source
implementation of Tailscale's control server. All the services I self host run
on Raspberry Pis and other machines at home & are reverse proxied through
tailscale.
Caddy - Batteries included reverse proxy that
handles TLS really well. Caddyfile is so much simpler than nginx configuration
and the API allows for nice automation.
Reposilite - Self-hosted maven
repository. The docker-compose version just works.
