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)
