Pick a name, roll a number, spin a wheel, or shuffle a list - all in your browser. Every randomizer runs locally with the Web Crypto API. No signup, no ads, nothing leaves your device.
ToolMatic's randomizers cover the everyday picks and rolls you reach for - drawing a name, rolling a number, spinning a wheel - without installing anything or leaving your browser.
Whether you are running a classroom raffle, picking a winner from a comment thread, choosing where to eat tonight, or generating values for a test, these tools are built to be quick, fair, and friction-free.
Every tool in this category runs entirely in your browser. Random values are produced with the Web Crypto API, the same cryptographically strong source modern browsers use for security primitives.
How to choose the right tool
To pick a name from a list, the Wheel of Names turns your roster into an animated spinning wheel - perfect for classrooms, raffles, and giveaway streams.
For numbers, dice rolls, or coin flips, the Random Number Generator handles any range, any count, with or without duplicates - powered by the Web Crypto API.
Every randomizer here runs offline after the first page load. Your list, your range, your seed, and your results never leave the browser tab.
Frequently asked questions
Yes - every randomizer tool on ToolMatic is completely free. There is no account, no signup, and no usage limit. Open any tool and start using it immediately.
ToolMatic randomizers draw values from the Web Crypto API (window.crypto.getRandomValues), the cryptographically strong random source built into modern browsers. This is the same source used for generating session tokens and cryptographic keys, and it is far stronger than Math.random(). Truly unpredictable randomness still comes from physical sources, but for picking names, rolling dice, or running raffles, Web Crypto is more than fair.
No. All ToolMatic randomizers run entirely in your browser. The names, items, or ranges you enter are never transmitted to ToolMatic servers. You can verify this yourself by opening your browser's DevTools Network tab - you will see zero outbound requests carrying your data.
An internet connection is required for the first load. Once the page is loaded, the randomizers continue to work because they execute entirely in your browser using JavaScript. Offline-first support via service-worker caching is planned for a future release.
Yes. The Wheel of Names is designed for classroom picks, livestream giveaways, and team-meeting raffles, and the Random Number Generator works well for ticket-based draws. For high-stakes or regulated draws (lotteries, compliance audits), use a tool that can produce a verifiable, signed result and keep an external record of inputs and outputs.
A Random Number Generator returns one or more values from a numeric range - good for dice rolls, coin flips, ticket draws, and generating test data. A Wheel of Names takes a custom list of items and animates a spin to one of them - good for naming a winner, deciding what to do, or making the reveal visible to a group.
