Cline Cline
Cline is an open-source autonomous AI coding agent available as a VS Code extension, JetBrains plugin, CLI, and SDK. It features a Plan-and-Act workflow where the agent proposes tasks, edits files, and runs terminal commands, always requiring human-in-the-loop approval by default.
Recent major updates include the release of Cline CLI 2.0 with improved interactive terminal UI, support for parallel agent instances on a web-based Kanban board, and enhanced SDK capabilities for multi-agent orchestration.
As of
- Plan and Act workflow with per-step human approval
- Autonomous multi-file editing and terminal command execution
- Broad model compatibility (Claude, GPT, Gemini, local Ollama, and more)
- Native support for Model Context Protocol (MCP) to connect external tools
- Headless CLI mode for CI/CD pipelines and automated workflows
Developers who need a highly autonomous agent for complex refactoring, repository-wide tasks, or projects requiring custom tool integrations via MCP.
Developers who prefer a zero-setup, all-in-one IDE experience with inline autocomplete, or those who want a flat, predictable monthly billing structure without managing inference costs.
The tool is free and open-source. Users pay for model inference via their own API keys (bring-your-own-key) or through an optional $9.99/month ClinePass subscription that provides access to curated open-weight models.
Cline is arguably the most capable open-source autonomous agent for developers who value transparency, model flexibility, and deep control over their coding environment.
