Code IDE vs Code Runner

Code IDE brings a complete programming environment to your iPhone and iPad. Write, compile, and run code in 50+ languages — including Python, Java, C++, and JavaScript. Your built-in AI Agent autonomously plans, builds, and debugs entire projects for you. AUTONOMOUS AI CODING AGENT Your AI Agent handles complete project workflows — from scaffolding to debugging: • Auto-Build Projects — Describe what you want. The AI creates the full folder structure, files, and boilerplate automatically. • PLAN Mode & AUTO Mode — Review a detailed technical blueprint before execution, or let the agent run end-to-end autonomously. • AI Debugging — The agent scans your file tree, pinpoints logic errors, and applies patches automatically. • AI Memory — The agent remembers your coding style and project context across sessions for a personalised experience. • Human-in-the-Loop — Granular permission settings and approval prompts mean the AI never acts without your consent.
