What QuizLive is
QuizLive is a free, open-source real-time multiplayer quiz and trivia platform that runs as a self-hosted web app. It offers live polling, live Q&A and quiz modes, with players joining from phones by scanning a QR code or opening a URL without accounts. The host view shows questions, a timer, answer charts and a leaderboard. An admin panel manages questions, game flow, QR settings and session history. Faster correct answers receive higher scores, and previous session leaderboards can be downloaded as CSV files. QuizLive can operate on a local network without internet access. Its documented stack uses Firebase Firestore and Authentication, with Vercel hosting or self-hosting; the README identifies Firebase plus Vercel as the only setup tested end-to-end. The maker estimates Firebase’s free tier for about 80–100 concurrent players, while larger events need pay-as-you-go service. Security rules protect admin actions, answer keys and submitted scores. Commercial or revenue-generating use is disallowed.
