About this app

PolyDev turns your phone into a complete dev studio with an AI agent built in. Write, run and ship real projects — no laptop required.

🤖 AI agent that works with your code
Describe what you want and the agent reads your project, creates and edits files, fixes bugs and refactors — right inside your repo. Not just a chat: a real coding partner.

🧑‍💻 A full code editor (IDE)
File tree, tabs, syntax highlighting and live error checking as you type. Built-in Git: commit locally, browse history and publish to GitHub.

💻 A real terminal on your device
A built-in Linux environment (Alpine) with Node.js, npm, Python, PHP and Go. Install packages, run scripts and build projects like on a computer — no SSH, no remote server.

📱 Live preview
Watch your app run in real time without leaving PolyDev. Test your backend with the built-in API tester.

🚀 One-tap deploy
Ship to Vercel and Cloudflare Pages with a single tap and get a live link to share.

🧩 20+ ready-made stacks
React, Vue, Svelte, Angular, Next.js, Nuxt • Django, FastAPI, Flask, Express, NestJS, Laravel, Go • Telegram and Discord bots • Phaser and Three.js games • React Native (Expo) • or plain HTML, CSS and JavaScript.

🔑 Your choice of AI
Start free with the built-in AI, or bring your own API key — OpenAI, Anthropic, Google, OpenRouter and more. Track token usage and spending per model.

🌍 11 languages
Light and dark themes, custom accent colors and fonts.

Code from anywhere — on the commute, in the queue, on the couch. A full dev environment in your pocket.
