Cline

Cline helps developers write, edit, and debug code, automate coding tasks, and manage projects with AI models, terminal commands, and IDE integrations while keeping control over coding workflows.

At a Glance

Pricing Free

Cline works as an open-source AI coding agent that helps developers write, edit, refactor, and debug code. Available through VS Code, JetBrains integrations, and command-line workflows, it can inspect project files, execute terminal commands, and handle multi-file coding tasks.

Unlike basic code autocomplete tools, Cline can plan and execute coding tasks with user approval. It also supports multiple AI models, custom project rules, and external tools through the Model Context Protocol (MCP).

How Cline Works

  • Prompt & Context Gathering: Describe a coding task, such as refactoring a module or fixing a bug, inside the Cline panel.
  • Planning: Cline inspects project files, reads .clinerules, and creates a step-by-step plan.
  • Execution & Approval: It proposes file edits and terminal commands, allowing you to approve or reject the actions.
  • Verification: Cline can run tests, identify errors, and make further changes to help complete the task.
