Clacify's Random Number Generator produces one or multiple random numbers within any range you specify — minimum value, maximum value, quantity, and whether duplicates are allowed. Uses your browser's crypto.getRandomValues() for true randomness (not pseudo-random). Useful for classroom lucky draws, lotteries, board game decisions, statistical sampling, and any situation requiring unbiased random number selection.
Open Clacify's Random Number Generator, set Min to 1 and Max to 100, and click Generate. A cryptographically random number between 1 and 100 appears instantly. Click again for a new random number. Each result has an equal 1% probability — truly fair.
Clacify's Random Number Generator uses the browser's crypto.getRandomValues() API, which produces cryptographically secure random numbers based on hardware entropy — truly random, not pseudo-random. This is the same randomness standard used in secure encryption and digital signatures.
