EchoTube

EchoTube is the kind of project that makes you wonder why Google hasn't just built this themselves — an open-source YouTube client that runs ad-free, needs no account, and keeps everything local on your device. The on-device recommendation engine that learns from your watch patterns without sending data anywhere is the real flex here, and it's exactly the kind of privacy-first thinking that's resonating with users right now. It's very early with just 96 followers and 91 points on Product Hunt, so whether this becomes a sleeper hit or just another privacy-focused app that tech Twitter praises for a week and forgets about remains to be seen, but the concept alone is the move.
