This is Google's own open-source Design Sprint methodology hub: not a UI or wireframe kit, but a guide to running the five-day Design Sprint process Google developed internally, plus a library of the exercises and templates used at each stage.
The real value is the structured method itself: how to plan a sprint, run each day's exercises, and turn the output into a testable prototype: genuinely useful process discipline, not visual assets.
Best for a product or design lead planning to actually run a design sprint with a team, not someone browsing for wireframe components to drop into a file.
Since it's a process guide rather than a downloadable kit, don't expect Figma files or PSDs here: the templates are more workshop worksheets than reusable UI pieces.
