## What it is
A browser extension that automatically detects HTTP Live Streaming (HLS) playlists on web pages and lets users download selected video and audio tracks. It merges segments locally into MP4 or MKV files using ffmpeg.wasm, with no uploads or external servers.

## Use cases
- download hls streams from browser
- save m3u8 video as mp4
- capture live stream segments from a webpage
- download specific video quality and audio language tracks
- merge hls fragments into a single video file locally
- sniff streaming playlists without devtools

## When to choose
- you need to download HLS video entirely in-browser with privacy (no uploads)
- you want fine-grained control over video resolution and audio track selection
- you use Firefox, Edge, Chrome, Brave, or another Chromium-based browser

## When to avoid
- you need to download DASH or non-HLS streaming formats
- you need a command-line or headless downloader like yt-dlp
- you need to bypass DRM-protected streams
