What Yarn Spinner is
Yarn Spinner is a set of narrative game tools for writing, integrating, and testing dialogue and branching stories. Its human-readable Yarn language is designed for interactive conversations, with official integrations for Unity, Godot using C# or GDScript, and Unreal Engine using Blueprint or C++. The free, open-source Visual Studio Code extension provides syntax highlighting, error checking, a graph view, and an in-editor dialogue preview. Dialogue strings can be exported with unique IDs, and language switching can happen at runtime; Yarn Spinner can also use Unity Localization. Voice-over tools cover audio asset management, localization synchronization, and playback timing. Ready-made add-ons include speech bubbles and dialogue wheels; Text Animator is included in Yarn Spinner+. Try Yarn Spinner provides a browser-based way to write and run scripts without setup, but its scripts stay in browser localStorage and are not backed up or synchronized. The core is licensed under MIT. The Free plan is listed as free; Yarn Spinner+ for Unity is 75.00 USD or more, once.

Verdict
Yarn Spinner brings dialogue authoring, engine integrations, localization, and voice-over tools into one narrative workflow. Its free extension and browser tool are useful starting points, but browser scripts require separate care because they are not backed up.
