Features

🪟

Native window

Dedicated app window — no browser tabs, no distractions. Lives in your Dock and ⌘+Tab like any app.

🔐

Persistent session

Log in once, stay logged in. Session is stored locally in the system WebView data store.

📋

Clipboard fixed

Paste with ⌘+V works everywhere — WKWebView clipboard restriction bypassed natively.

⚡

Tiny & fast

Single ~2 MB binary. No Electron, no bundled Chromium. Uses the system WebKit engine.

🔓

Open source

~30 lines of Go. Read it, build it yourself, modify it. MIT licensed.

🌐

System WebView

macOS uses WKWebKit (Safari engine). Windows uses WebView2. Linux uses WebKitGTK.

Documentation

Requirements

macOS — first launch

macOS Gatekeeper will block the binary because it is unsigned. To allow it:

# Remove quarantine flag xattr -dr com.apple.quarantine mistral-vibe-mac-arm64 # Then launch ./mistral-vibe-mac-arm64

Or right-click the binary in Finder → Open → Open in the dialog.

Linux — install dependency

# Debian / Ubuntu sudo apt install libwebkit2gtk-4.0-dev # Fedora sudo dnf install webkit2gtk4.0-devel

Build from source

git clone https://github.com/thib-d/mistral-vibe-gui cd mistral-vibe-gui go build -o mistral-vibe . ./mistral-vibe

Paste not working?

Paste (⌘+V / Ctrl+V) is handled by a JS bridge built into the app — it bypasses the WKWebView clipboard restriction. If it stops working after a Mistral site update, please open an issue.
