Kilo Code

Kilo Code is an open-source AI coding agent that plugs into VS Code, JetBrains IDEs, a CLI, Slack, and a hosted cloud runner. It ships five operating modes — Code, Architect, Debug, Ask, and Custom — alongside whole-codebase context, a code review pass, and an auto model router that picks an appropriate model per task. The project is Apache 2.0 licensed and visible on GitHub, so teams can self-host or fork it instead of paying for a closed tool.

What differentiates it from Cursor or Copilot is the pricing posture and model freedom: there is no inference markup, you can bring your own API keys (OpenAI, Anthropic, OpenRouter, local models via Ollama, etc.), and there is no vendor lock-in. A free tier is available with no credit card, and Kilo Pass offers a flat subscription for managed inference if you do not want to wire up your own keys. The landing page name-checks usage at Meta, Amazon, Airbnb, PayPal, Square, and Red Hat, which positions it for serious individual developers as well as engineering teams.

The broader ecosystem includes OpenClaw managed hosting for agents (no Docker or SSH plumbing) and an emerging cloud/Slack surface for asynchronous agent work. Caveat: with 500+ supported models and five modes, the surface area is large, and quality varies considerably depending on which model you point it at — the auto-router helps but does not eliminate the need to tune.
