CoinFlipFree is a small set of free tools for making random choices: a coin flipper, a yes or no coin and a dice roller, plus a plain-English guide to coin flip probability.
What we care about
- Fairness. Every result comes from the browser's cryptographically secure random number generator, without bias.
- Speed. No sign-ups, no pop-ups, no heavy frameworks. The tools load in a blink and work on any phone.
- Privacy. Your stats live in your own browser. We never see your flips.
- Accessibility. Keyboard shortcuts, screen-reader announcements and reduced-motion support are built in.
