Autonomous coding agent in your IDE that creates/edits files, runs commands, uses browser, and more with your permission.
Cline is an autonomous coding agent that operates directly within your IDE (VS Code). It can create and edit files, execute terminal commands, use a headless browser, and extend its capabilities via the Model Context Protocol (MCP). All actions require user permission, providing a safe human-in-the-loop experience. It supports multiple AI models including Claude, GPT, Gemini, and local models via Ollama/LM Studio.

Use Cases
lightbulbDevelopers convert UI mockup images into functional web apps by describing the design; Cline creates files, runs dev server, and iterates based on screenshots.
lightbulbEngineers debug runtime errors by asking Cline to launch the app in a headless browser, capture console logs, and fix visual bugs automatically.
lightbulbTeams automate repetitive coding tasks like adding new API endpoints: Cline edits files, runs tests, and monitors for compilation errors.
lightbulbProject managers generate Jira ticket summaries by asking Cline to add a custom MCP tool that fetches ticket details and integrates them into the workflow.
lightbulbDevOps engineers manage cloud infrastructure by instructing Cline to create an MCP tool that checks EC2 metrics and scales instances up or down.
lightbulbOpen source contributors quickly understand large codebases: Cline analyzes file structure, runs regex searches, and reads relevant files to provide context-aware assistance.
lightbulbQA testers perform end-to-end testing by asking Cline to run the app, navigate through pages, and report any visual or functional issues found.
