This tool downloads direct video files through a serverless proxy that bypasses CORS restrictions. It works like this:
Paste a direct video URL (must end in .mp4, .webm, etc.)
Click "Start Download" — the file streams to your browser
The browser saves it to your default download folder
Why won't YouTube/Bilibili work? These platforms use HLS/DASH streaming with CORS restrictions and DRM protection — no pure frontend tool can download them.
For streaming platforms, you'll need yt-dlp, FFmpeg, or a dedicated backend service.
