Random

Random number, value and choice generators.

Nickname Generator

Generate nicknames and usernames from words, random letters or your own name, with seven themes and presets that match the name format of Minecraft, Roblox, Discord and other platforms.

Random Number Generator

Generate a random number, a list, or multiple sets of numbers in any range — for Lotto and EuroMillions lines, office sweepstakes, tombolas and classroom draws — right in your browser.

Coin Flip

Flip up to 12 coins at once and get heads or tails with an exact 50/50 chance, tossed in 3D on a real coin and decided in your browser by cryptographically secure randomness.

Dice Roller

Throw up to 20 virtual dice in your browser, from a d2 coin flip to a d1000, with the total worked out as they land. Cryptographically secure, free, and nothing leaves your device.

Random Picker

Paste any list — names, ideas or tasks — and let this free tool choose fairly. Every draw runs locally using cryptographically secure randomness, meaning your list never leaves your device.

Security

Strong Password Generator

Create strong random passwords from a cryptographically secure source right in your browser — for GOV.UK, HMRC and online banking alike. Full control over character types, and nothing ever leaves your device.

Development

URL Slug Generator

Turn any title into a clean URL slug in your browser — one at a time or a whole list at once. Real transliteration standards for Cyrillic and accents, editable rules, and nothing ever uploaded.

UUID Generator

Generate UUIDs in your browser: fully random v4, time-ordered v7 for database keys, or deterministic v5 from a namespace and a name. Up to 1000 at once, and nothing ever leaves your device.

Design

Random Colour Generator

Generate up to 50 random colours at once — any colour, or only vivid, pastel or dark ones — each with its HEX, RGB or HSL code and a text-contrast badge, made in your browser with secure randomness.
