Downpour

Free, open-source video downloader for macOS, Windows, and Linux. Paste a link, see the video, pick a quality, download. Powered by yt-dlp, so it works with YouTube, Vimeo, Dailymotion, X, and 1800+ other sites.

No terminal, no Python, no manual installs: Downpour provisions its own download engine automatically.

Grab the latest build from Releases.

brew install --cask 0xharkirat/tap/downpour

This taps 0xharkirat/homebrew-tap and installs Downpour.app. Update later with brew upgrade --cask downpour.

Homebrew 6 and newer refuse to load casks from an untrusted third-party tap. If you see "Refusing to load cask ... from untrusted tap", trust it once:

brew trust 0xharkirat/tap

The cask clears the download quarantine as it installs, so Gatekeeper should not block the first launch.

The DMG is universal: one download for Apple Silicon and Intel.

1. Download Downpour.dmg and open it.
2. Drag Downpour onto the Applications shortcut.
3. Open Downpour from Applications. macOS will say it cannot verify the app; click Done (not "Move to Bin").
4. Go to System Settings > Privacy & Security, scroll down, and click Open Anyway, then confirm. You only do this once.

Terminal alternative to steps 3-4:

xattr -dr com.apple.quarantine /Applications/Downpour.app

This dance exists because the build is ad-hoc signed rather than notarized by Apple.

1. Download Downpour-windows-x64.zip and extract it anywhere (for example C:\Program Files\Downpour).
2. Run downpour.exe. If SmartScreen appears, click More info, then Run anyway.

1. Download Downpour-linux-x64.tar.gz and extract it: tar -xzf Downpour-linux-x64.tar.gz
2. Run ./downpour/downpour. Needs GTK 3 and libnotify, present on most desktop distros (Debian/Ubuntu: sudo apt install libgtk-3-0 libnotify4).

Downpour looks for yt-dlp and ffmpeg on your system. If they are missing, it downloads the official builds into its own data folder with progress shown in the app. Nothing is installed system-wide.

• Preview before downloading: thumbnail, title, uploader, duration.
• Quality presets: Best, 4K, 1080p, 720p, and audio-only MP3. The finished item shows what was actually downloaded.
• Live progress with speed and ETA. Cancel, open, reveal in folder, download again.
• Download history that survives restarts.
• Video transcripts from platform captions, saved as a text file next to the video.
• System notification when a download finishes.
• One-click engine updates (sites break old yt-dlp versions regularly).
• Drag a link from your browser straight onto the window.
• Light, dark, and system themes.

Requires Flutter 3.44+.

flutter pub get
flutter run -d macos    # or windows / linux

Tests:

flutter test test/                        # unit
flutter test integration_test -d macos    # end to end (downloads a real video)

Optional: bundle the engine into a release build so first launch needs no download at all:

flutter build macos --release
dart tool/bundle_engine.dart macos

• lib/src/core/engine_manager.dart provisions yt-dlp + ffmpeg: custom path, then managed copy, then bundled, then system install, then download.
• lib/src/core/ytdlp_service.dart runs yt-dlp and streams typed progress events parsed from --progress-template output.
• lib/src/features/ holds the UI (forui + Riverpod 3 + go_router); download history lives in a drift database.

MIT. Downpour is a GUI for yt-dlp. Respect the terms of service of the sites you download from and only download content you have the right to save.
