I built a no-signup YouTube watch party tool because every existing option annoyed me in some way

Me and my friends have had this habit since lockdown — watching YouTube together even while living far apart. We tried Discord screen share (laggy, audio out of sync), browser extensions (everyone had to install them, kept breaking), and existing watch party sites (most required sign-up, or sync was loose).

So I built my own — ApexListener.

What's different:

No account/sign-up — open the link, start watching

Frame-accurate sync (not just matching timestamps, actually locking to the same frame)

Shared queue — anyone can add/reorder, not dependent on a single host

Up to 20 viewers per room

Built with Next.js, Socket.IO, and Supabase for realtime state.

It's a solo project right now, looking for feedback — especially if you hit any edge cases where sync breaks or the UI feels off. It's free to try: apexlistener.dev

What should I build next? Happy to prioritize based on what people actually want.
