The Interface

Try Yarn Spinner has two main panels:

  • Editor (left) — where you write your Yarn scripts. Supports syntax highlighting, line numbers, and multiple nodes.
  • Runner (right) — where your dialogue plays. Lines appear as they run, and options are presented as clickable buttons.

Writing and Running

Type or paste a Yarn script into the editor, then press the Run button in the top-right corner. The runner will start executing from the first node.

You can stop a running script at any time, edit your code, and run again. Changes take effect immediately — there’s no separate build or compile step.

Sharing Scripts

Try Yarn Spinner can generate a shareable link to your script. Use the File menu to share your work with teammates, students, or friends.

Size limit on shared scriptsBecause shared scripts don’t actually get stored on a server, but instead get encoded into the share URL, there is a maximum script size. If your script exceeds the size, the Share Link feature will be disabled.

What’s Next

Try Yarn Spinner is perfect for learning and prototyping. When you’re ready for multi-file projects, graph views, and deeper editing tools, move on to setting up Yarn Spinner for Visual Studio Code.
