Kilo Code Overview

Kilo Code is an open-source AI agent extension that can be integrated into VS Code.

Architect mode: Plan designs and structures before writing code.
Code mode: Implement based on design.
Debug mode: Supports finding and fixing bugs.

Other useful features

Source-Powered Code Accuracy: Utilize Context7 and refer to the library’s official documentation to generate reliable code based on real-world APIs.
Error recovery function: Automatically run tests and automatically attempt to recover when problems occur.
No API key required or free: You can prepare your own API key or use a local model. You will receive up to $25 in free credits.
Model Context Protocol (MCP) Marketplace: A marketplace for JSON-based integration of external tools and custom features.
Personal customization: You can freely customize prompts, models, modes, and environment settings for a flexible development experience.

Advantages as an open source

It is a fork of Roo Code and Cline, and it is evolving while integrating the best of both worlds.
