About JustBuzz
JustBuzz is a free, browser-based quiz buzzer. Players join a room by pasting a room code, while hosts create a room and receive a shareable link to invite participants. The room has no stated limit on the number of users, and the interface is designed to work on phones, tablets and other screen sizes.
Players can buzz in with an on-screen button or the spacebar, and they can type answers into a text field and send them along with the buzz. Hosts can play a sound when someone buzzes, which can be toggled off, and can clear individual or all buzzes or remove users from the room. The site also mentions azigy, a separate app for creating and hosting live quizzes and trivia.
