About Kilo
Kilo is an open-source AI coding agent that works in VS Code, JetBrains, the CLI, and the cloud. It offers an intelligent coding assistant with code completion and generation, supports parallel isolated worktrees, and can carry sessions over between the IDE and the CLI. Its gateway provides access to 500+ models (frontier models, open-weight models, or your own keys), and the vendor states that there is no markup on AI inference, with support for bring-your-own keys and local models. The project is open source under the MIT license; prompts, context windows, and decisions can be reviewed in the source code, and it can be forked, modified, or self-hosted.
Best for
Best use cases
Developers who need to use the same AI coding agent in an IDE, terminal command line, or cloud environment
Teams that want to choose their own models, bring their own API keys, or run local models without being locked into a single vendor
Teams that need to review prompts and context, or audit and security-assess the agent's source code
Features
Multi-Environment Agent
Use the same agent in VS Code, JetBrains, the CLI, or the cloud, and control all agents from one place — local and cloud agents, parallel isolated worktrees, and IDE-to-CLI session handoff are all supported.
500+ Models to Choose From
Access 500+ models through a unified gateway (frontier models, open-weight models, or your own keys); the official website states there is no inference markup and no vendor lock-in.
Intelligent Coding and Code Completion
An intelligent coding assistant providing code completion and generation capabilities.
Open Source and Auditable
Prompts, context windows, and decisions are auditable in the MIT-licensed source code; you can fork, modify, and self-host, and models are never silently switched.
