i have a couple tools ive been working on…

retrovibed - a jellyfin/plex alternative that fully virtualizes its p2p torrent network in userspace read: it protects your activities without messing with your system, and setup is drag & drop wireguard config to enable and its search plugin system replicates the *arr stack (mostly) but is actually secure enough to run untrusted plugins. no system / local network access for plugins.

egdaemon a local first compute platform with GPU capabilities. I use to it replace ci/cd and ML training platforms and to almost fully virtualize my development environments.

both are highly focused on user experience (though both still have some rough edges)

proof is in the pudding as they say. sounds like you have your own issues.

https://bartosz.fenski.pl/modern-fs-benchmark/ benchmarks say it all.

Same, and next year when bcachefs has nailed down the kinks it’ll be basically bullet proof with snapshotting prior to its daily updates.
