For what reason are you trying to avoid docker? since most projects provide docker images and an example docker-compose.yml it’s very easy to get the application you want running.

Otger projects that do plug and play application setup like yunohost etc. are casaOS and umbrel (both use docker under the hood btw)

In what way is Deezer support broken?

On brave it worked fine

If you use let’s encrypt certificates on that subdomain it’s pretty easy to find. https://crt.sh/
