You can self host anything like this, all you need is buying a domain and set something up like DynDNS which updates the entry of the domain with your new IPv4 as soon as it changes.

I would recommend to not open your services to public, but set up a wireguard (or other VPN) endpoint in your home, which you then use to access all your services.

I think, an alternative to that would be some servicees from tailscale or cloudflare, I suppose
