Open-source AI coding agent offering code generation, autocomplete, and terminal automation across IDEs.
Kilo Code is an open-source AI coding agent that generates code from natural language, automates tasks, and runs terminal commands. It ships with inline autocomplete, browser automation, automated refactoring, and custom modes for planning, coding, and debugging, and supports more than 500 AI models alongside bring-your-own-key and local-model options.
The agent runs in VS Code, JetBrains IDEs, a command-line interface, and cloud environments, with a model gateway that prices inference at cost. Its source is MIT-licensed and it is distributed through the Open VSX registry.
