The Lucide Lab family proof page with "Random (50)" mode active — showing 50 randomly sampled icons from the full set of 373. The subtitle reads: "Experimental icon set • 373 creative icons • Extension of Lucide."
Lucide Lab contains more specialized and experimental icons not found in the core Lucide set — things like frog-face, unicorn-head, cauldron, floppy-disk-2, surfboard, and hedgehog that appear in the screenshot. The same controls are present as on other family pages: search, variant (Outline), icons per page (50), Refresh, and Random.
Both the Lucide and Lucide Lab snapshots were taken with "Random (50)" active, which illustrates a key feature of the proofs system: randomized sampling lets you quickly assess the character and range of a family without scrolling through thousands of icons. Comparing the two screenshots side-by-side shows the tonal difference between a production icon set (Lucide) and an experimental extension (Lucide Lab).
