What is Kilo?

Kilo is an open-source AI coding agent that works inside VS Code, JetBrains IDEs, and the command line. It connects to over 500 AI models with no markup on inference costs, and lets you bring your own API keys or use Kilo's managed gateway. The core product is free. You pay for the AI you use, nothing more. The company was founded by Sid Sijbrandij, who co-founded GitLab and led it for years before it went public. His co-founder Scott Breitenother built and sold Brooklyn Data, a data consultancy. That's a team that knows developer tooling and understands what engineering organizations actually need. The company raised $8 million in seed funding from General Catalyst, Cota Capital, and others, and has grown to 2.3 million users while processing over 25 trillion tokens since launch. **The model flexibility is the core pitch.** Most AI coding tools tie you to one provider's models and pricing. Kilo runs on 500+ models through its gateway at zero markup, covers OpenRouter, and supports local models via Ollama or LM Studio. If you have your own API keys for Claude, GPT-4, or Gemini, you plug them in and the tool routes through your account. There are no surprise bills from Kilo…
