JIT.dev

Enables chatting with AI to generate, edit, preview, and collaborate on code instantly. Publish AI artifacts, let agents work in isolated live variants, compare exact proposals, and decide what ships. JIT.dev is a browser-based AI Code Playground where you chat with AI models to generate, edit, run, and collaborate on code with live previews and instant sharing. Everything runs in your web browser; just sign in and start a new playground. It handles virtually all languages since execution happens through integrated runtimes or previews tailored to common ones. Real-time collaboration lets several users edit simultaneously with live updates visible to everyone. The core features including chat, generation, previews, and public sharing are available for free, with Pro adding privacy and priority options. It focuses more on AI-driven chat, agents, and lightweight browser collab, while Cursor integrates deeply with local IDEs and Replit offers stronger compute for bigger apps.
