Yarn Spinner

Yarn Spinner is an interpreter for the Yarn language, written in C#. We plan to build a suite of tools, including a Yarn Spinner editor, and many other things.

Yarn is a language that's designed to make it super easy to create interactive dialogue for games. Yarn's very similar in style to Twine, so if you already know that, you'll be right at home! If you don't, that's cool - Yarn's syntax is extremely minimal, and there's not much there to learn. Yarn's used in a number of cool games, including Night In The Woods and Knights and Bikes.

Important: Yarn Spinner is still under development, and we haven't made our 1.0 release yet. It's probably fine to use right now, but there are a few bits and pieces that might change between now and first release.

Yarn Spinner is designed to be easy to add to Unity games, but it's also intended for use in other contexts as well.


Yarn Spinner is available under the MIT License. This means that you can use it in any commercial or noncommercial project. The only requirement is that you need to include attribution in your game's docs. A credit would be very, very nice, too, but isn't required.

Made by Secret Lab!

Yarn Spinner was originally created by Secret Lab, an Australian game dev studio! Come say hi! We hope you like it!
