Develop full-stack projects on Android with an AI-powered IDE
Experience running, testing, and deploying full-stack projects directly from your phone: the AI agent reads projects, edits files, and runs a terminal inside the app. PolyDev: AI Coding Agent, from xApi Devs, is an Android utilities tool that bundles a full IDE, an Alpine Linux runtime, Git integration, and one-tap deployment. It targets developers, students, and hobbyists who need a portable development studio that manages code, fixes bugs, and ships web apps on the go.
What the tool actually does for mobile development
PolyDev inspects and modifies real projects on-device. The agent has direct access to the file system and terminal, so it can create and edit files across a repository and apply multi-file fixes rather than only returning code snippets. The app includes a file tree, tabs, syntax highlighting, and live error checking, and it supports over 20 ready-made stacks such as React, Next.js, and FastAPI.
How it interacts with the device and runtime environment
The environment runs locally inside an Alpine Linux container. That container provides multiple language runtimes (Node.js, npm, Python, PHP, Go), which lets builds and tests execute on the device without an external server or SSH. Integrated Git support handles local commits, history browsing, and publishing to hosted repositories, keeping version control operations entirely within the mobile studio.
Safety, workflow options, and who needs technical knowledge
The agentic AI works with both built-in models and user-supplied API keys. You can choose the built-in model or connect keys from OpenAI, Anthropic, Google, or OpenRouter. Live preview and API testing provide immediate feedback during edits, while one-tap deployment to Vercel and Cloudflare Pages creates shareable live links. The IDE surface (file tree, tabs, live errors) supports both quick edits and deeper refactors, so developers with basic Git experience can operate the tool.
A practical mobile studio for developers who code on Android
PolyDev fits developers, students, and hobbyists who need a standalone Android development studio that performs repository edits and deploys from a single device. Its design assumes you work on Android devices only, so teams that require cross-platform desktop tooling should plan around that platform restriction. For anyone committed to coding on a phone, it delivers a focused, device-contained workflow with deployment paths included.
