Neostream Video Grabber is a JavaScript monorepo delivering an Electron desktop download manager paired with a Manifest V3 Chrome extension. The extension scans pages for obvious media and sends selected items to a local HTTP bridge where the desktop app queues, persists, and manages downloads. It supports direct file downloads and authorized HLS/M3U8 streams via FFmpeg (with custom headers), plus pause/resume/cancel/retry, download history, tray/menu-bar behavior, and configurable settings. Built with Electron, React, Vite and Node.js, the project uses electron-store for settings, zustand for state, and electron-builder for cross-platform packaging.
