Overview

Cline is an AI assistant that works in your editor and CLI with a human‑in‑the‑loop workflow. Powered by agentic coding, it tackles multi‑step development tasks by reading and writing files, searching large projects, using a browser for end‑to‑end checks, and running terminal commands after you approve each step. Through the Model Context Protocol (MCP), Cline can create custom tools to extend its capabilities on demand. Instead of unsafe automation, the extension provides reviewable diffs and command approvals, giving a safe way to explore agentic AI in real projects while tracking tokens and API cost across the loop.

💡

Use Cases

Turn mockups into apps

Attach images and let Cline translate sketches into working UI or use screenshots to fix bugs.

Onboard to large repos

Analyze structure, ASTs, and patterns with targeted reads to build context without exceeding windows.

Automate terminal tasks

Install packages, run builds, tests, and deployments with shell integration and step approvals.

Browser‑driven debugging

Launch a site, click and type, capture screenshots and logs to resolve runtime and visual issues.

Augment context and checkpoints

Add URLs, problems, files, or folders, and use snapshot compare/restore to safely iterate.
