Questions people ask
Is PolyDev really free to use?
Yes, it ships with a built-in free AI tier so you can start coding with no card and no setup; for heavier use you can connect your own API key and pay that provider's rate directly.
Do I need to root my Android phone to use PolyDev?
No, PolyDev runs a real Alpine Linux environment through PRoot without root access or a remote server.
Can I deploy my project straight from my phone?
Yes, PolyDev offers one-tap deploy to Vercel or Cloudflare Pages with .env sync and deploy history, can push to GitHub from its built-in Git panel, and can build Android APK/AAB files in the cloud.
Which AI models or providers can I use with PolyDev?
You can bring your own key from providers like OpenAI, Anthropic, Gemini, OpenRouter, Mistral, Groq, Ollama, DeepSeek, or Hugging Face, or point PolyDev at any OpenAI-compatible endpoint; a built-in free tier is also available with no key needed.
Does PolyDev work without an internet connection?
The on-device terminal and live preview work offline since the dev server runs on your phone, but the AI agent needs an internet connection to reach whichever model provider you choose, since only the model runs in the cloud.
