Pick & Random Tools

Why use a browser randomizer?

From deciding who picks tonight's restaurant to running a fair raffle draw, a reliable random picker removes bias and disputes. All tools here use the browser's crypto.getRandomValues() API — the same source used for cryptographic key generation — so results are genuinely unpredictable, not just pseudo-random.

Every tool is shareable: results encode into the URL so you can send a link to friends and they'll see exactly what you picked. Try the Wheel of Names for classroom draws, the Dice Roller for tabletop RPGs, or the List Shuffler for randomizing any ordered list.
