Cline

Overview

Cline is an open-source AI coding agent for Visual Studio Code that helps developers automate software engineering tasks through autonomous, agent-driven workflows. Rather than providing only code completion or chat-based assistance, Cline is designed to understand entire projects, reason across repositories, and execute complex development tasks while keeping developers in control of the process.

As a VS Code extension, Cline integrates directly into existing development environments, allowing developers to collaborate with AI without leaving their editor. It also supports multiple AI providers, giving users the flexibility to choose the models that best fit their workflows.
