What server/self-hosted software would you like a desktop/mobile app version of?
Think of some stuff you may already self-host but it'd make it easier (and maybe keep your config simpler) to suggest to others if it had a desktop/mobile app version
For text to speech I'd recommend Kaldi. It's just the android engine and has nothing else to configure/look at, but the quality of the output is really natural. FOSS, fully offline running locally.
I think it'd be pretty sweet to get like a single executable installation for a VPN server that internally generates a cert and then assembles a new executable that'll install and a VPN with that cert pre-configured.
Basically "Run this program on the computer you want as the server then run the program it gives you on a computer you want as the client." It'd make it really easy to proselytize against things like NordVPN.
I just want more apps to support sync-to-file so they're compatible with Syncthing.
Home server with in/out VPN, system auto - back up, hosting FreshRSS just to "subscribe" and sync YouTube channels. Why can't NewPipe at least just add auto backup at the very least. Sigh.
