Open source AI coding agent for VS Code, JetBrains and the terminal, with 500 plus models billed at provider rates.
Kilo Code is an AI coding agent that follows you between editors, running as a VS Code extension, a JetBrains plugin and a command line tool from one project. Pricing is open: you choose from more than 500 models, switch between them mid task, and pay the model provider's rate with no markup, without needing API keys to begin.
Work is divided among specialized agents you switch between, and you can define your own. Code implements and edits, Plan designs architecture before anything is written, Ask answers questions without touching files, Debug traces issues, and Review surfaces problems across performance, security, style and test coverage.
Around those agents sit the tools they use.
- Inline autocomplete: ghost text suggestions accepted with the tab key.
- Self checking: the agent reviews and corrects its own work.
- Terminal and browser control: running commands and automating the web.
- MCP marketplace: a place to find and wire up servers that extend what the agent can do.
Installation covers the VS Code Marketplace, the JetBrains plugin repository and the CLI through npm, Homebrew, the Arch User Repository or prebuilt binaries. For pipelines, an autonomous run flag removes every permission prompt, which the project advises using only in trusted environments. The code is MIT licensed, and the CLI began as a fork of OpenCode.
