Real-time analysis – Detect unclosed brackets, quotes, and block comments while you type.
Multi-language syntax highlighting – Powered by highlight.js with automatic language detection or manual selection.
Comment awareness – Understands //, --, and /* … */ comments to avoid false positives.

# Install dependencies
npm install

# Start the development server
npm run dev

# Then open http://localhost:3000 in your browser

Enter your original command or code in the Command text area.
Enter one or more payloads in the Injection List.
To choose specific injection positions, insert placeholders such as {{INJECT}}, {{INJECT2}}, … inside the command. If no placeholder is present the first injection is appended to the end.
The combined result is shown instantly with syntax highlighting and balance status.

Path	Purpose
`app/page.tsx`	Main UI and logic
`app/globals.css`	Global styles and `highlight.js` theme
`package.json`	Project dependencies (includes `highlight.js`)

The app is a standard Next.js 15 (App Router) project and can be deployed directly to Vercel or any Node.js hosting service.
