Random
Generators built on the browser's cryptographically secure random source (crypto.getRandomValues): strong passwords, UUIDs, dice rolls, coin flips, lottery numbers, or picking a winner from a list. Because the randomness is produced by your own browser, no server ever sees or logs a result — useful whenever an outcome has to be demonstrably fair.
