Random Number Generator
Generate cryptographically secure random numbers within any range — unique or with repeats.
Frequently Asked Questions
Is this truly random?
We use crypto.getRandomValues, which is a cryptographically secure pseudo-random number generator (CSPRNG). Sufficient for games, sampling, and security use cases.
What's the limit for unique numbers?
For unique mode, count cannot exceed (max − min + 1). We cap the generation range at 1,000,000 values for performance.
