Random generators

Whether you need a strong password, a batch of UUIDs for test data, a random number for a giveaway or a few paragraphs of lorem ipsum for a mockup, these generators produce it instantly. The set also covers random strings with configurable character sets, random word lists, dice rolls, MAC addresses and ready-made Google Calendar event links.

Where randomness has security consequences — passwords, random strings, UUIDs — the values come from your browser's cryptographically secure random source (the Web Crypto API), not from a predictable pseudo-random function. That is the same quality of randomness password managers use, and it is the difference between a password that resists guessing and one that only looks random.

Generation happens entirely on your device, which matters more here than anywhere: a password created on a server exists in that server's logs and memory; a password created locally exists only on your screen until you copy it. Nothing is transmitted, nothing is stored, and refreshing gives you a fresh value every time.
