Random Bit String Generator

Produce N independent fair bits as a 0/1 string — optionally grouped for readability.

Options

Generate a random string of 0/1 bits (each fair & independent). Optional fixed-width grouping.

Uses your browser’s Web Crypto CSPRNG (crypto.getRandomValues) — strong PRNG for games, picks, and development. Not atmospheric true-random like RANDOM.ORG.
