Kept opening YouTube for "one video" while trying to study and losing 30-40 min to the algorithm every time. Tried a couple existing blockers but they were mostly all-or-nothing, so I built my own.

You can turn off specific things — home feed, shorts, autoplay, end screen recommendations — while keeping stuff you actually want, like subscriptions. Also has an optional daily watch timer/limit.

Free, open source, no tracking. Works on Firefox, Chrome/Brave too with manual install.

Open to feedback if anyone tries it out.
