very similar, but seems a bit more polished is https://coder.com, you can write your own terraform modules and run it on whatever cloud you want.
It was especially cool connecting my ipad and having the ability to work (although somewhat impractical without a separate keyboard).
That had nothing to do with CodeServer except that it was all running on the same box. So access to my code server was limited only to VPN clients, making it more secure; and I only had to connect to one place with my tablet and laptop.
Of course, any services on the server which would make remote requests would also get filtered through the Pi-Hole, so they too might be sped up a bit as any ad gabage would be stripped away.
