We make a lot of decisions with random tools — standups, team assignments, dinner choices — and we got tired of tools that stored our data, served ads over the result, or required an account just to export a custom wheel.
The specific frustration was spin history. Several popular wheel spinners log your results to a server by default. That is unnecessary for a random number generator. There is no reason a spin result needs to leave your device.
Every tool on Spinness runs in the browser. The randomness is generated locally using the Web Crypto API. Nothing is sent to a server because there is no server receiving it.
The tool set covers the cases that come up most often: a wheel spinner for any custom list, a random name picker for classroom draws, a random number generator with configurable ranges, and a team randomizer for splitting groups. We built these because they were the four things we kept doing manually or on tools we did not trust.
The audience is broader than we expected. Teachers use the name picker for cold-calling without bias. Dev teams use the wheel for retrospective formats. Trivia nights use it to assign categories. People use the number generator for giveaways where they want the draw to be obviously fair and obviously random.
There are no ads overlaid on the result. There is no premium tier required to save a custom wheel. The wheels are saved in your browser's local storage, which means they persist on your device and only your device.
