About this extension
GrabLine Connect pairs your browser with GrabLine, the free and open-source download manager (AGPL-3.0). The extension is deliberately thin—it detects and delivers, while the desktop app downloads.

• Right-click → "Download with GrabLine" on any link, image, video, or page
• Hover button on videos, audio, and large images
• Per-tab media list: every stream (.m3u8/.mpd) and media file the page loaded
• Download all images on a page into a selection grid
• Optional download takeover (off by default)

On sites the Smart Engine knows (YouTube and 1000+ more), the app opens a quality panel with options from 4K to 144p, MP3/M4A extraction, subtitles, and clip trimming. Everywhere else you get segmented, resumable, multi-connection downloading.

Requires the free GrabLine desktop app (Windows/macOS/Linux): https://github.com/Gr33nOps/GrabLine. The extension communicates with it using Native Messaging only. No account, no cloud, no telemetry, and no ads.

GrabLine does not bypass DRM or logins.
