Installation

Desktop app (recommended)

1. Download the latest .dmg from Releases
2. Open the DMG and drag to Applications
3. Right-click → Open to bypass Gatekeeper (build is unsigned)

The desktop app bundles the review CLI — no separate install needed. You just need Node.js 18+ installed.

CLI (standalone)

echo "@flpstudio:registry=https://npm.pkg.github.com" >> .npmrc
npm install -g @flpstudio/lgtm

From source

git clone https://github.com/flpstudio/lgtm.git
cd lgtm
npm install
npm run build
npx lgtm

Workspace app (from source)

cd workspace
npm install
npm run tauri:dev    # Dev mode with hot reload
npm run tauri:build  # Production build
