CKEditor Raffle

The booth raffle tool: a web-based winner picker with slot-machine spin, confetti, and cryptographically fair selection - names come from a local text file, nothing gets stored or tracked.

What's inside

A web raffle that reads participant names from a local names.txt, spins them slot-machine style, and celebrates the winner with confetti. Selection uses cryptographically secure randomness, and because everything is local, there is no storing or tracking of participants - which is exactly what you want at a conference booth.

Why it exists

Battle-tested at CKEditor conference booths (the T3DD raffle with ~100 participants ran on it). Spacebar to spin.
