Jacker is a small Tauri desktop wrapper around yt-dlp.

It accepts a YouTube video or playlist URL, probes metadata before downloading, shows the thumbnail/title, builds the quality dropdown from real available formats, and streams download progress from bundled yt-dlp.

The packaged app bundles yt-dlp and FFmpeg. End users do not need to install Node.js, Rust, Python, yt-dlp, FFmpeg, Homebrew, or any other command-line dependency before downloading videos.

The macOS bundles are written under:

src-tauri/target/release/bundle/

Source development requires Node.js 20+ and Rust/Cargo. The build downloads a standalone yt-dlp binary and copies a standalone FFmpeg binary into src-tauri/binaries/ automatically.

npm install
npm run tauri dev

npm run tauri build

• The default download folder is ~/Downloads/Jacker; the app creates it when the first download starts.
• Best available is always offered. Resolution options are discovered from yt-dlp metadata for the inspected URL.
• Playlist ranges only appear after the URL is detected as a playlist.
• Conversion and embedding options use the bundled FFmpeg binary.
