Kilo Code is an open-source AI coding agent for developers. Its website positions it as "one open agent for every developer workflow." The same agent is available from several entry points, including the IDE, the terminal, the cloud and Slack, so developers don't have to switch back and forth between different tools.
Key features
- Multi-platform coverage: Offers a VS Code extension (which also works with Cursor, Windsurf and other editors compatible with Open VSX), a JetBrains plugin (IntelliJ IDEA, PyCharm, WebStorm and more), a command-line tool, a desktop app (Beta), a cloud agent, a Slack integration and a mobile app.
- Multiple specialized agents: Built-in modes such as Ask, Plan, Code and Debug, plus support for custom modes. Code writes and refactors code, Plan maps out complex features before you start, and Debug locates and fixes bugs.
- Freedom of model choice: Supports 500+ models, including frontier models and open-weight models. The website states there is zero markup on AI inference, and it supports bringing your own API keys as well as local models for privacy.
- Auto Model routing: Offers three strategies, Efficient, Frontier and Free, and automatically picks a suitable model for you.
- Unified agent management: Manage local and cloud agents from a single place, with support for parallel, isolated worktrees and for IDE and CLI sessions.
- Cloud agents and code review: Launch an agent from the browser, or invoke it by mentioning @Kilo in Slack. The website also lists other products such as Code Reviewer and Security Agent.
- Transparent and auditable: The source code is released under the MIT license, you can inspect prompts and context windows, and the website says it never silently switches models. Forking, modifying and self-hosting are allowed.
Target users and use cases
It suits individual developers who want AI-assisted coding without being locked into a single model or tool, as well as teams and enterprises that want to manage their AI coding tools in one place. The website also offers Enterprise and Teams plans, along with comparison pages and migration guides for products such as Cursor, GitHub Copilot, Claude Code, Cline and Roo Code.
