Generators
Test fixtures, seed data, primary keys and credentials all need values that are unpredictable and correctly formatted. Every generator here draws from the browser’s cryptographically secure random source rather than Math.random(), so the output is safe to use for identifiers and secrets — and because generation is local, a password you create is never transmitted anywhere.
UUID Generator Generate v4 and v7 UUIDs in bulk, with formatting options and one-click copy. Password Generator Create strong random passwords or passphrases, with a real entropy estimate in bits. Random String Generator Build random strings from exactly the character set and length you specify. Nano ID Generator Generate compact URL-safe Nano IDs with a live collision-probability estimate. Random Number Generator Draw random integers or decimals in a range, with optional uniqueness and sorting. Lorem Ipsum Generator Generate placeholder paragraphs, sentences, words or list items for mockups.
