ShareYT
A browser extension that lets you share YouTube videos with friends and see what they're watching.
ShareYT is a browser extension that makes sharing YouTube videos with friends easy and social.
The Problem
YouTube’s native sharing feels disconnected. You share a link, your friend watches it later (maybe), and there’s no sense of watching things together.
The Solution
ShareYT adds a social layer to YouTube:
- Friend system – Connect with people you actually want to share videos with
- Easy sharing – One-click share right from the YouTube page
- Feed – See what your friends are sharing in real-time
- Notifications – Get notified when friends share something you might like
Tech Stack
- JavaScript browser extension (Chrome/Firefox)
- Firebase for backend (Auth, Firestore, Functions)
- Vanilla CSS for styling
What I Learned
Building this taught me a lot about:
- Content scripts and browser extension architecture
- Firebase security rules and cost optimization
- Building for multiple browsers
