ClassCaddy is a free suite of classroom tools for teachers: spinner-wheel name picker, group maker, timers, scoreboard, and seating chart — all sharing one class roster. No accounts, no premium tier; rosters stay in the teacher's browser. Cryptographic randomness with a published 250,000-draw fairness audit.

Every tool shares one class roster, so a teacher imports the class list once and all tools stay in sync. The wheel picker uses cryptographic randomness (Web Crypto) and the project publishes a 250,000-draw fairness audit for anyone to inspect. ClassCaddy works on any classroom screen or interactive whiteboard, needs no installation, and never asks students to create accounts. Tools included: random name picker wheel, random student picker, group maker and team generator, countdown timer, classroom stopwatch, scoreboard for class games, noise-friendly big display mode, and a printable seating chart builder. Built for primary and secondary teachers, and useful for workshops, training sessions, and after-school clubs.
