Cline Freemium

What is Cline? Cline (formerly Claude Dev) is a powerful open-source autonomous coding agent that runs directly inside Visual Studio Code. Unlike simple autocomplete assistants, Cline can read and write files, execute terminal commands, browse the web, and iterate on its own work until a task is complete. It is model-agnostic, working with Anthropic, OpenAI, Google Gemini, OpenRouter, Ollama, and any OpenAI-compatible endpoint, which makes it a favorite among developers who want maximum flexibility and control over cost.
