Revolt is kinda “centralized”. You can host your own version, but they seem to actively discourage you from doing so.

https://github.com/jgraph/drawio/blame/dev/LICENSE <-- that’s … a rather specific and recent change. Is there a story here ?

You are aware that draw.io is itself open source and self-hostable: https://github.com/jgraph/drawio ?

At $dayjob I switched from Apache to nginx 15+ years ago. It’s Callback/Event based process model ran circles around Apache’s pre-fork model at the time. It was very carefully developed to be secure, and even early on it had a good track record. Being able to have nginx handle static content without tying up a backend worker process was huge, and let us scale our app pretty well for the investment of time. Since then, Apache implemented threaded + Event based process models, Caddy, traefik, and a bunch of others have entered the scene.

TBH, I think the big thing nowadays is sane defaults, and better configuration, even automatically discovered configuration – traefik is my current favorite for discovering hosts in consul/Kubernetes/simple host definition files, but since traefik can’t directly serve files, I simply proxy from traefik to … nginx :)

Navidrome is another server that works pretty well, implements the subsonic protocol ( so all the apps that can cache and stream to your mobile device work). You can have multiple logins, or just share out playlists and albums individually to non-authenticated users.
