About Cline

Cline is one of the leading open-source autonomous AI coding agents for Visual Studio Code, originally created by Saoud Rizwan and now maintained by the Cline team in San Francisco. The agent operates as a VS Code extension that can read and edit files, execute terminal commands, browse the web, and use the Model Context Protocol (MCP) to extend its capabilities. Cline supports frontier models from Anthropic Claude, OpenAI GPT, Google Gemini, DeepSeek, and local models via Ollama, providing a bring-your-own-API-key model. With over one million installs from the VS Code marketplace, Cline has become a popular choice for developers wanting agentic coding without subscription lock-in.
