Most multistream setups are just browser tabs. Multistream is a desktop app built with Tauri, Rust, and Vue 3: Twitch, Kick, and YouTube side by side in one window, using less memory than a single Chrome tab, with no trackers or background processes.

Why Multistream?

Feature	Multistream	Browser tabs / Web tools
Memory usage	Low (Tauri + Rust)	High (separate Chromium processes per tab)
Chat	Unified Twitch & Kick feed	Split across separate tabs
Privacy	100% local, zero tracking	Third-party scripts and telemetry
Stream recording	Direct recording to MP4 via Streamlink	Requires external tools or extensions
Live transcription	Offline Whisper.cpp on CPU	Not supported natively

Features

• Privacy by design: Everything runs locally. No middleman servers, no data collection.
• Account Authentication & Unified Chat: Log in to your Twitch and Kick accounts securely and read both chats together in one place, directly in the app. Free, no subscription. Supports 7TV, BTTV, and platform emotes.
• Direct from the source: Streams load from the official players, so your views count and quality is exactly the same as on the platform itself.
• Lightweight: Built with Tauri and Rust, so memory usage is a fraction of what any browser-based alternative would use.
• Local stream recording: Record streams directly from the source using Streamlink. Recordings are processed natively without heavy sidecars, keeping the app extremely lightweight, and are automatically remuxed to MP4 when finished.
• Available in 10 languages: English, Portuguese, Spanish, German, Russian, Chinese, French, Turkish, Hindi, and Indonesian. (Note: Languages other than English and Portuguese were AI-translated. Native speakers are highly welcome to open a PR to improve them!)
• Cross-platform: Works on Windows, macOS, and Linux.
• Local AI transcription: (Windows only) Real-time transcription powered by Whisper.cpp, running fully offline on your CPU. Useful for streams in languages you don't speak. No API keys, no costs, no audio ever leaves your machine.

Important for macOS Users

As a free, open-source project, Multistream is distributed without a paid Apple Developer certificate. This causes macOS Gatekeeper to flag the application as "damaged" by default.

If you see the error "Multistream is damaged and can't be opened", you have two options:

1. Install via Homebrew (Recommended):

brew install --cask ilanzgx/multistream/multistream

2. Fix manually after downloading the DMG:

Move Multistream.app to your /Applications folder, then run:

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

Keyboard Shortcuts

You can navigate the app quickly using these global hotkeys (they even work when you are interacting with a stream iframe):

Shortcut	Action
1 - 9	Switch active chat tab to the corresponding stream number
D	Open the "Add Stream" dialog
S	Take a screenshot of the focused stream
