Random Generator is a growing collection of quick, no-signup random generators. Pick a category in the sidebar, hit Generate, get an instant result — no accounts, no clutter. Useful for games, writing prompts, classroom icebreakers, raffles, class assignments, research sampling, or any time you'd rather not decide something yourself.
Everything is sorted into eighteen categories, each with its own page listing what's in it: Dice, Everyday, Nature & Science, Space & Astronomy, Math & Numbers, Food & Drink, Names, Sci-Fi, Fantasy & RPG, Places & Culture, History & Time, Words & Language, Life & Leisure, Arts & Media, Pattern, Video Games, Sports & Games, Business & Brands, Party & Icebreakers, Card, Tools, Animal, Plant & Fungus, Rock & Mineral, Landscape, Weather & Sky, Human Body, Celestial Object, Spaceflight, Number, Math Practice, Geometry, Math Lore, Food & Ingredient, Meal, Sweets & Coffee, Cocktail, Fantasy Character, Kingdom, Adventure, Divination, Myth & Legend, Historical Event, Historical Figure, Artifact & Record, Media, Streaming, Music, Design, Sport & Exercise, Chess, Business Name, Company & Brand, Work & Idea, Party Game, Question, Laughs & Wild Card.
Every draw on this site, from a coin-flip filter to a 20-sided die, is sourced from crypto.getRandomValues() — the Web Crypto API's CSPRNG (cryptographically secure pseudorandom number generator) — instead of Math.random(). Math.random() is backed by a fast PRNG (V8 uses an algorithm called xorshift128+) that's built for speed and statistical distribution, not unpredictability: its internal state is only 128 bits, and observing enough consecutive outputs is enough to reconstruct that state and predict every value the generator will produce afterward. crypto.getRandomValues() instead draws straight from the operating system's entropy pool — the same source used to generate encryption keys — so there's no internal state to reverse-engineer. In practice this makes zero difference to a d20 roll, but it does mean the numbers, dice, and shuffles here hold up to the same standard as a password generator or a cryptographic nonce, not just a UI animation. Draws also go through rejection sampling rather than a plain modulo, so ranges that don't evenly divide the generator's output space (rolling a d6, say) don't get a biased distribution where some faces are ever-so-slightly more likely than others.
The library falls into a few broad kinds of generator. Most draw from curated datasets — animals, countries, elements, films, foods, historical figures, chess openings and a few hundred more — where each entry has been checked and usually carries the fact worth knowing about it alongside the name; most can be narrowed by category and drawn several at a time. Others are generative: rather than picking a name off a list they compose one from word banks and naming patterns, so fantasy names, tavern names, prophecies and whole grammatical sentences are effectively unlimited and never repeat exactly. A third kind is computed rather than picked at all — the dice roll a true N-sided value, the maths pages build a fresh problem with a clean whole-number answer, and the Art & Patterns group draws its result rather than choosing it. A few run on a list you type in yourself, like the Wheel of Names, the Team Splitter and the Tournament Bracket. One reaches the network: the Wikipedia Page generator fetches a genuinely random article from Wikipedia's own API on every roll. And a handful are built for developers and designers, where the point is that the output is correct rather than merely plausible — real version 4 and version 7 UUIDs with their version and variant bits set, and fake phone numbers and addresses drawn only from the ranges regulators reserve for fiction, so they can never reach anybody.
Five generators exist to answer the same question from different angles: Cuisine picks from 132 world and regional cooking traditions, Protein from 134 cuts across meat, fish, shellfish and plant-based options, Cooking Method from 114 real techniques, Sauce from 116 classics and condiments, and Side Dish from 118 named dishes. Stacked together they become the Random Meal preset, which decides dinner in one press.
The Art & Patterns group draws rather than picks: a heraldic Coat of Arms with its blazon written out, a perfect Maze with exactly one way through, symmetric Mandala and spirograph line art, live Conway's Game of Life and Langton's Ant boards you can draw on, Fractals from the random tree to the dragon curve, Walk Art's wandering line drawings, a slowly turning Kaleidoscope, a Stained Glass window built as a true Voronoi mosaic, a mirrored Pixel Monster with a name to match, Constellation and Solar System Makers that chart invented skies, and a Flag Designer that raises the flag of a country that doesn't exist (their cousins, the Dungeon Map and Island Map, live with the Fantasy generators). Every design unfolds deterministically from a seed stamped on its card, so a favorite can always be redrawn.
A matching Sci-Fi set does the same for somewhere that isn't Earth: Alien Planet picks from 114 planet types, Alien Biome from 102 landscapes, Alien Species from 114 biologies, Alien Civilization from 102 ways a society can be organised, and World Hazard from 100 reasons a place is dangerous. The Alien World preset stacks all five. These are deliberately kept apart from the Space & Astronomy generators, where every entry is a real catalogued object.
The sidebar splits into Basic (the dice, the Everyday generators, and the Tools -- pickers like Wheel of Names, Spin the Bottle, the Ladder Game, Card Draw, Plinko, Team Splitter, the Tournament Bracket, the List Randomizer, and the Bingo Card generator that draw from your own list, quick deciders like Coinflip, Magic 8-Ball, and Lottery Numbers, plus a Word Scrambler that turns any word into a puzzle and a Word Unscrambler that finds every real word hiding in a set of jumbled letters), Explore (every other generator above, on its own), Games (party generators like Would You Rather, Truth or Dare, Never Have I Ever, Charades, and Riddles, plus the card table: draw a Playing Card or deal a Poker Hand from a fairly shuffled deck), and Presets — bundles that stack several related generators into one window for a single click, for whenever you want a complete result rather than one piece at a time (a drink concept, an invented kingdom, a whole meal, and more to come). Any generator in a preset can still be removed or regenerated on its own, and more can be added alongside it, exactly like building a stack by hand.
Every generator remembers how you left it — the categories you filtered to, how many results you asked for, and your last few draws — so coming back to one picks up where you stopped. Once you've changed something, a link button appears beside Copy that copies a link reopening that generator configured exactly the same way, and a window holding several generators has a Share window button at its foot that does the same for the whole stack. The links carry the setup, never the results: whoever opens one draws their own.
Dozens more categories — from Dog Names to Fortune 500 companies — are marked "Soon" in the sidebar and will unlock one by one as they ship, each with the same fast, no-signup experience.
