Cline

Cline is an open-source autonomous coding agent that runs directly inside your IDE (VS Code and JetBrains), capable of creating and editing files, executing terminal commands, browsing the web, and integrating with external tools through the Model Context Protocol (MCP). Trusted by over 5 million developers worldwide, Cline operates on a bring-your-own-key model, giving you full control over which AI provider powers your coding workflow.

Key Capabilities

Cline features dual Plan/Act modes where the agent first devises a strategy and then executes it with your approval at every step. It can read entire project structures, search within files, run terminal commands, and launch headless browsers for web development tasks including clicking, typing, scrolling, and capturing screenshots. The Model Context Protocol (MCP) integration extends Cline's capabilities by connecting to external tools and data sources. Cline supports all major AI providers including OpenAI, Anthropic, Google, and local models.

Who Should Use Cline

Cline is ideal for developers who want an autonomous coding assistant without vendor lock-in or recurring subscription fees. It suits individual developers who prefer terminal-first workflows, teams looking for centralized billing with role-based access, and enterprises needing SSO, audit logs, and VPC deployments. Its open-source nature makes it particularly attractive to developers who value transparency and customization.

Getting Started

Install the Cline extension from the VS Code or JetBrains marketplace. Configure your preferred AI provider by entering your API key in the settings. Start a conversation by describing what you want to build or fix, and Cline will create a plan, then execute it step by step with your permission at each stage.

Pricing & Accessibility: Cline is free and open-source. You only pay for AI inference through your chosen provider's API pricing. The Open Source Teams plan is free for the first 10 seats (then $20/seat/month) and includes centralized billing, team management, and JetBrains support. Enterprise pricing is custom and includes SSO, SCIM, audit logs, and SLA guarantees.

Why Consider Cline: Cline delivers the power of an autonomous coding agent without subscription fees or vendor lock-in, letting you choose any AI model while maintaining full transparency through its open-source codebase and step-by-step approval workflow.
