CatPaw

Overview

CatPaw is an AI-powered integrated development environment (IDE) created by Meituan, designed to help developers focus on creative implementation and accelerate project delivery. As a smart coding partner, CatPaw embeds artificial intelligence directly into the coding workflow, reducing interruptions and enabling developers to stay in their flow.

Core features include intelligent code completion, a quick Q&A mode that generates code snippets on demand, built-in preview and debugging tools, and project-level analysis. With codebase indexing, the AI assistant can understand the context of the entire project, offering more precise suggestions. CatPaw supports mainstream programming languages such as Python, Java, JavaScript, and others, making it versatile for a wide range of development scenarios.

CatPaw is compatible with macOS 10.15 and above, and a Windows version is currently in development. By automating routine tasks and providing intelligent assistance, CatPaw empowers developers to concentrate on what matters most—bringing ideas to life—while significantly improving development efficiency and project delivery speed.

Core capabilities

Code completion (Tab)

Provides real-time code suggestions during coding, helping developers complete code quickly.

Quick Q&A code generation (Agent)

Acts as a powerful AI assistant, answering coding questions and generating code snippets directly in the IDE without switching tools.

Built-in preview and debugging (Browser)

Supports instant preview and debugging of front-end code, sending selected elements to AI chat for smart modifications.

Project-level analysis (Codebase)

Uses codebase indexing so the AI assistant understands the entire project context, delivering more accurate intelligent suggestions.
