I Built a YouTube Bookmark Manager Using Vanilla JavaScript (No Backend, No Login)

Hey devs 👋 I recently built a YouTube Video Library Web App that lets you save and organize videos in a way that feels more like a personal library than YouTube playlists. 🔗 Live Demo: https://ytbookmark.vercel.app/ 💡 The Problem YouTube playlists are useful… but only to a point. Hard to organize large collections No custom grouping beyond playlists No quick way to manage or filter content Everything is tied to your account After saving hundreds of videos, it started to feel messy and limiting. 🧠 The Idea I wanted a simple, private, and flexible way to: Save videos quickly Organize them however I want Access them without logging in Keep everything in one clean interface So I built my own YouTube video library. ⚙️ Tech Stack HTML CSS Vanilla JavaScript localStorage PWA (Progressive Web App) No frameworks. No backend. Fully client-side. ** ✨ Features ** 📌 Core Features Save YouTube video links Auto-generate thumbnails Organize videos into custom groups Instant search and filtering ⭐ Prod
