StreamGrabber 🚀

A high-performance, lightweight userscript designed for seamless media extraction/video downloader. Detect and download HLS streams (.m3u8), video blobs, and direct video files with a minimal, premium UI.

📥 Installation

[!IMPORTANT] Recommended Userscript Manager: Violentmonkey

While StreamGrabber works on most managers, Violentmonkey provides the best compatibility and performance for modern userscripts.

  1. Install a manager: Violentmonkey (Recommended)
  2. Add Script: Click here to install.
  3. Confirm: Accept the installation in your browser extension.

✨ Key Features

  • Smart HLS Processing: Parallel segment downloading with AES-128 decryption and fMP4 support.
  • Unified Terminal UI: A single, clean floating action button (FAB) that manages all detected media across nested iframes.
  • Adaptive Quality: Automatically picks up master playlists and offers resolution selection (e.g., 1080p, 720p).
  • Resilient Downloads: Built-in pause/resume functionality with automatic retry mechanisms for unstable connections.
  • Privacy First: Minimal permissions, no external tracking, and works entirely within your browser context.

  4. Monitor: Track progress in real-time with the compact progress cards.

📜 Changelog

v2.1.0

  • Modular Download Engine: Refactored the core download logic to eliminate "God Functions", ensuring better stability and maintainability.
  • Enhanced Resilience: Added smart 403 fallback mechanisms for strict HLS segments and verified robust pause/resume functionality.
  • UI Polish: Updated FAB aesthetics with a modern squircle design and improved progress bar visualization.
  • Namespace Update: Migrated to streamgrabber-lite namespace.

v2.0.0

  • Shadow DOM Isolation: Re-engineered the entire UI layer to use Shadow DOM. This encapsulates styles and DOM nodes, preventing "hydration failed" errors on sites built with React, Next.js, and other modern frameworks.
  • Hydration-Safe Architecture: The UI host is now detached from the main document body's tree, ensuring 100% isolation from host-side script interference.
  • Premium Gold Theme: Implemented a new, sleek design system with gold accents, enhanced typography, and micro-animations.
  • Dynamic Progress Engine: Improved download scheduler with verified percentage tracking and gold-gradient filling.

v1.3.0

  • HLS Enhancements: Improved playlist enrichment and resolution detection.
  • UI Refinement: Cleaner animations and better responsive layout for mobile.
  • Performance: Optimized memory usage during large concurrent downloads.

v1.2.5

  • Unified UI: Global aggregation of media from all sub-frames.
  • Compatibility: Enhanced support for fMP4 and diverse HLS encryption schemes.
