What Kilo Code is
Kilo Code is an open-source coding agent available as a VS Code extension, JetBrains plugin, CLI, and cloud/web interface. It emphasizes open pricing: you pay the model provider’s rate with zero markup.
Key features
- 500+ models - GPT-5.5, Claude Opus 4.7, Claude Sonnet 4.6, Gemini 3.1 Pro Preview, and many more.
- Mid-task model switching - change models without losing context.
- Built-in agents - Code, Plan, Ask, Debug, and Review modes.
- Inline autocomplete - ghost-text suggestions with tab-to-accept.
- Self-checking - the agent reviews and corrects its own work.
- Terminal and browser control - runs commands and automates web actions.
- MCP marketplace - discover and wire up MCP servers.
Install
VS Code extension, JetBrains plugin, or CLI via npm/curl/pnpm/bun/Homebrew/AUR. Binaries are also on GitHub Releases.
Use case
Kilo Code is a strong choice if you want an open-source agent with transparent, provider-cost pricing and a wide model selection. The VS Code extension is the most polished interface.

Honest caveat
“No API keys required to start” usually means a hosted onboarding path; for production use you will bring your own keys. Read the pricing page carefully before committing.
