In their own words
Kilo Code
Kilo Code is an open-source AI coding assistant for IDEs, terminals, browsers, and mobile devices. It can generate, refactor, and debug code, automate reviews, and deploy applications, with code completion, chat assistance, codebase indexing, and terminal access. Users can access more than 500 models across more than 60 providers, including free, local, and bring-your-own-key options. Kilo is available as extensions for VS Code and JetBrains editors, as a terminal CLI, and through cloud agents. Its modes include Code, Architect, Debug, Custom, and Auto; Auto Model routes tasks through Efficient, Frontier, or Free strategies. Cloud agents run remotely and can create branches, with optional commits and pushes. The source is MIT-licensed and can be inspected, modified, or self-hosted. The Free plan costs nothing, with usage billed separately; the Auto Free option requires no hosted credit and can route to free models where available. Teams costs $15 a month ($15/user/month). Kilo Pass subscriptions start at $19 a month, and the Enterprise trial lasts 14 days.
