Random Number Generator — Min, Max, Bulk, Unique

Generate one or many random integers in any range. Toggle "unique only" to avoid duplicates. Uses crypto.getRandomValues for true randomness.

About this tool

True random, not pseudo-random

Most sites use Math.random() — predictable and not safe for any actual decision making. We use the browser's crypto.getRandomValues, the same function used to generate session tokens. Set min, max, count, and whether duplicates are allowed.
