Kilo Code – An open-source VS Code AI Agent extension tool

What is Kilo Code?

Kilo Code is an open-source AI Agent extension for Visual Studio Code that enhances developer productivity. It offers powerful code generation capabilities, allowing users to quickly generate code snippets based on natural language descriptions—significantly reducing manual coding time. Kilo Code automates a variety of repetitive programming tasks, such as code formatting, refactoring, and boilerplate generation, further boosting efficiency. It comes with built-in access to the latest AI models like Claude 3.7 Sonnet and Gemini 2.5 Pro, and requires no manual API key configuration. Kilo Code also features an MCP Server Marketplace, enabling users to easily discover and utilize various MCP servers to extend agent functionality for different development scenarios.
