In-Depth Review: What is Cline?
Cline is an open source AI coding agent that integrates seamlessly into your IDE, CLI, and SDK. It enables coordinated multi-file edits, live bash command execution, and a Plan then Act workflow.

Core Features
Multi-file Edits
Coordinated multi-file changes with linter-aware fixes, diffs, checkpoints, and one-click undo on every step.
Bash Command Execution
Executes bash commands in your terminal and reacts to output live, handling long-running dev servers, tests, and deploys.
Plan-and-Act Mode
Toggle Plan mode to align on a strategy, then Act to execute, with approval on every step or auto-approve for autopilot.
Rules and Skills
Ship .clinerules with your repo to teach the agent your coding standards, architecture, and deployment conventions.
Multi-Model Support
Choose from Claude, GPT, Gemini, local Ollama/LM Studio, or any OpenAI-compatible endpoint. Bring your own key or weights.
MCP and Plugin Extensibility
Register custom tools and lifecycle hooks via the SDK; plug in MCP servers for databases, APIs, and infrastructure.
Multi-Agent Teams and Scheduling
Coordinator agents delegate to specialists with their own tools and context; run on cron for recurring automations.
