About kilocode

Kilo is an open-source, all-in-one agentic engineering platform designed to help developers build, ship, and iterate faster with AI-powered coding agents. It integrates directly into popular development environments including VS Code, JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm), and the command line interface (CLI), allowing developers to work with AI assistance wherever they code. The platform also offers cloud-based agent hosting and a managed service called KiloClaw that lets users deploy persistent agents without the complexity of self-hosting (no SSH, Docker, or YAML files needed). Kilo is built around the concept of multiple specialized agent modes—Code, Architect, Debug, Ask, and Custom—enabling users to switch contexts without switching tools.

FAQ

Is Kilo Code really free?

Yes, Kilo Code is free and open source (MIT license). You pay only for AI inference. You can use it with your own API keys, local models, or via Kilo Gateway pay-as-you-go with no subscription required.

What AI models does Kilo support?

Kilo supports 500+ models from every major provider via Kilo Gateway, including frontier models, open weight models, and local models (Ollama, LM Studio). You can bring your own keys or use Kilo's hosted credits with zero markup.

What is KiloClaw?

KiloClaw is a managed service that lets you deploy persistent OpenClaw agents in seconds. These always-on agents can perform shell commands, browser control, and scheduled automations, and are accessible via Telegram, Discord, or Slack.

How does Auto Model work?

Auto Model automatically routes your tasks to the most appropriate model based on a tier you choose (Efficient, Frontier, Balanced, or Free). It uses session-aware classification to optimize for cost and capability without manual model selection.
