What is Cline?

Cline is an open-source AI coding agent that lives inside your editor. It can read your codebase, propose edits, run terminal commands, browse the web, and call MCP tools, with the user in the loop for approvals. Where Cursor and Windsurf bundle the agent, the IDE, and the model billing into one subscription, Cline separates them: the agent itself is free and you bring your own model provider. The project has grown into one of the most popular open-source coding agents on GitHub, with a healthy contributor community and frequent releases.

Key features

Plan Mode lets the agent draft a plan in markdown that you can edit before any code changes. Act Mode then executes the plan step by step, asking permission for risky operations like running shell commands or writing to files. Checkpoints let you roll back the workspace to a known state if the agent goes off-track. Provider support is broad: Anthropic, OpenAI, Google, Mistral, Groq, OpenRouter, and local Ollama models all work out of the box. MCP server support means the agent can use the same tool ecosystem as Claude Desktop and Claude Code.

Pricing breakdown

The Cline extension is free under an open-source license. The only cost is the model inference you choose to run. With Anthropic Claude Sonnet, a typical productive session costs a few dollars; with frontier models on long-running tasks, expect higher spend. Cline also offers a managed inference plan that bundles model access with the agent. This simplifies billing for teams that want one invoice but is not required to use the product.

When to choose Cline

Cline is the right tool when you want full control over model choice, transparent token costs, and an open-source codebase you can audit or fork. It is especially good for developers who already maintain Anthropic or OpenAI API keys and would rather pay for tokens than for a subscription markup. If you want a polished, opinionated experience with a single price tag, Cursor or Windsurf will feel smoother. If you want the deepest integration with Anthropic models specifically, Claude Code is the more direct path.
