Cline

Cline is an open-source coding agent that runs in an editor, terminal, or embedded product. The official site presents IDE, CLI, SDK, SpecDriven, Plan, and MCP Marketplace surfaces, with support for macOS, Windows, and Linux through the CLI. It is designed for prompt-to-production development while keeping the developer in control of the workflow.

✨ Key Features

• Use an IDE coding agent — Work inside supported editors with an agentic development workflow.
• Run Cline in a terminal — Install the CLI and use it across macOS, Windows, and Linux.
• Embed the agent with an SDK — Integrate the runtime into another product where supported.
• Plan before implementation — Use the Plan surface to structure work before editing.
• Follow specifications — Use SpecDriven workflows for more deliberate implementation.
• Connect tools through MCP — Discover or use MCP integrations from the marketplace.
• Choose model and provider options — Use an open-choice workflow rather than a locked model experience.
• Keep code work reviewable — Work from prompts while retaining the ability to inspect and direct changes.

💳 Pricing

• Open-source Cline — The client remains free and supports bring-your-own-key workflows. Model-provider usage and infrastructure costs are separate.
• ClinePass — Standard rate US$9.99/month after any promotion period; additional processing fees may apply. It includes a curated set of open-weight models and plan quotas, rather than unlimited access to every provider model.
• Cline provider — A broader model list uses pay-as-you-go API rates.
• Enterprise — Contact sales for organization billing and management terms.

ClinePass and provider services are optional paid offers; they do not turn the open-source client into a required subscription. Confirm current included models, quotas and processing charges before purchase.
