Kilo Code

Open-source coding agent merging Cline and Roo Code

CodeFreemiumLLM-drafted

Part of this entry was LLM-drafted and is being polished.

Kilo Code is the merged successor to Cline and Roo Code, two popular open-source VS Code agent extensions. Bring-your-own-API-key model — Kilo doesn't charge for the agent, you pay your model provider directly. Heavy MCP and custom-mode support.

Editor's verdict

The right pick if you want full transparency and don't want to pay another monthly subscription on top of your Claude / OpenAI bill. UX is rougher than Cursor's polished IDE; you're trading polish for control and openness. Power users coming from Cline will feel right at home.
