Kilo

Kilo positions itself as one open agent for every developer workflow. A single agent runs everywhere you code: as an extension for VS Code and other Open VSX editors, a plugin for the JetBrains family, a CLI you can script into any shell or CI job, and cloud agents you can start from a browser. Specialized modes handle different jobs, so you can switch between writing and refactoring code, planning complex features, debugging failures, and reviewing changes without leaving the tool you are in.

Pricing and model routing are a central part of the pitch. Kilo says it passes model inference through at cost with no markup, and supports bringing your own API keys or running local models for privacy. An Auto Model feature picks between Efficient, Frontier, and Free routing strategies based on the work at hand and your budget, which helps teams avoid paying frontier prices for routine tasks.

Because the agent is MIT-licensed and open source, teams can inspect prompts, context windows, and model decisions, fork the project, or self-host it. Kilo reports millions of developers using the product and processes trillions of tokens monthly, and it works with teams through enterprise, team, and gateway offerings that connect to existing IDE, CRM-adjacent, and Slack workflows.
