❓ FREQUENT QUESTIONS

FAQ — Cline

Is Cline free?

Yes, Cline is a free open source tool. You only need an API key from an LLM provider (Anthropic, OpenAI, Gemini…) to use it. Some models like Gemini Flash are available for free.

What is the difference between Plan and Act modes?

Plan mode allows Cline to think and propose a strategy before acting. Act mode executes actions directly. You can switch between the two based on desired supervision level.

Does Cline work only with VS Code?

Cline is a VS Code extension. There is no standalone app at this time. It works therefore in all VS Code-based editors, including Cursor and some forks.

What is Cline's MCP Marketplace?

The MCP Marketplace is an integrated marketplace allowing installation of MCP servers (Model Context Protocol) that extend Cline’s capabilities: database access, web tools, third-party APIs, etc.

Is Cline secure for professional code?

Cline only sends your code to the LLM provider you configured. Using on-premise or local models, you can keep code completely private. Actions are always subject to your approval.
