# PickRandom.app

> Free online random selection tools: wheel spinner, coin flip, dice roller, raffle box, list picker, team splitter, yes/no decision maker, and secure generators for numbers, passwords, and text. Every outcome is drawn from a cryptographically secure random number generator (crypto.getRandomValues). No sign-up, no ads, and user inputs never leave the browser. A free, keyless JSON API exposes the same operations for developers and AI agents.
