Pick from Frontend, Service, Database, Cache, Queue, External API — or create a custom component. Place them on the canvas.

STEP 3
Walk through it
Hit Next to step through each interaction one at a time. The active step lights up, the rest fades. Perfect for design reviews, onboarding, and interviews.
