Step 1: Paste URL
Paste a public Facebook video URL. The system validates format and checks platform support before extraction starts.
How VidGrab Works
VidGrab uses a resolver pipeline optimized for speed and privacy-aware handling of temporary download links.
Step 2: Resolve Metadata
The backend uses yt-dlp through a controlled process call, then parses title, thumbnail, duration, and quality list into a normalized DTO.
Step 3: Download
Each quality option is exposed through temporary signed links. This avoids leaking raw extractor URLs in page markup and limits link lifetime.
Why This Design
Caching metadata for short periods improves repeat performance and cuts extractor load. Rate limits and honeypot validation help reduce abuse while preserving a fast user experience for real visitors.
