This is a cool idea but it still needs a lot more work and polish.

I'm having trouble scrolling through the dropdown menu of component types without triggering the panning/scrolling of the infinite wall of components behind the menu. I had to drag the scrollbar thumb to get that dropdown to scroll.

I don't know if it's just me (latest FireFox on macOS) but the background of each component's container is dark, while the space behind the containers is white. There's way too much contrast. I don't even think you need a visible container or border around each component - it makes them too hard to compare. Just have them all sitting there on a neutral light gray background - something a bit easier on the eyes.

Also I'm a bit disappointed because when you said UI components I thought you were referring to the more basic building blocks of the UI - buttons, controls, etc. as opposed to actual interfaces built out of those components. I figured it would be various types of scrollbars or buttons or other components from various OSs and applications - a thing where you can compare visual styles... I guess this really ties more into my own expectations and interests...

Scrolling in general needs to be much smoother. There's a lot of lag!
