## What it is
Parabolic is a graphical frontend for yt-dlp that downloads video and audio from hundreds of websites in formats like mp4, webm, mp3, opus, flac, and wav. It supports concurrent downloads, metadata and subtitle fetching, and runs on Linux (Flathub), Windows, and macOS, with companion browser extensions.

## Use cases
- download youtube videos
- save web video as mp4
- extract audio from youtube to mp3
- batch download playlists concurrently
- download video subtitles and metadata
- yt-dlp frontend with gui

## When to choose
- you want a friendly GUI instead of the yt-dlp command line
- you need multiple formats and concurrent downloads across Linux, Windows, or macOS
- you want a Flathub-native GNOME app with libadwaita design

## When to avoid
- you need a headless or scriptable downloader - use yt-dlp directly
- you only need a browser-based one-click downloader without a desktop app
- downloading may violate the site's terms or copyright law
