Cryptographically random tools for decisions, sampling, and simulations. Pick random items from a list, generate unbiased random numbers, shuffle any list, flip coins, and roll dice — all powered by the Web Crypto API for genuine randomness, not Math.random().

Five tools for genuine randomness: every coin flip, dice roll, list shuffle, and number draw seeds from window.crypto.getRandomValues — the same cryptographic source TLS handshakes use — never the predictable Math.random() that most online generators rely on. Use them for fair raffles, statistical sampling, simulations, decisions you want to be able to defend later. Each tool takes a configuration, runs entirely in your browser, and produces results you can copy, download, or send into another tool.
