Cline is an open-source AI coding agent that runs as a VS Code extension and CLI, planning and making multi-file changes with the model of your choice.

Our take

Last updated 29 October 2026

Cline is an open-source AI coding agent for VS Code and the command line that plans and makes multi-file changes, runs commands and asks for approval along the way. It is free for individual developers; you pay only for the AI models you use, either at cost through Cline or with your own API key. An Enterprise plan adds JetBrains support, SSO and admin controls.

Best for Game programmers who want an open-source agent in VS Code and control over model costs.

Pros

  • Free and open source.
  • Bring your own model or API key.
  • Approval steps keep you in control of changes.

Cons

  • Model costs can add up on large tasks.
  • Enterprise pricing is not public.
  • Not engine-aware out of the box for Unity or Unreal.
