What is Buzrr?

Buzrr is an open-source quiz platform that runs in the browser. A host builds a quiz — by hand or with AI — from multiple-choice, true/false, poll, word-cloud, rating and open-text questions, and opens a live room; players join from their own phones or laptops with a 6-character code, a link or a QR code, without creating an account. Signed-in users can also play ranked 1v1 quiz battles. Buzrr is licensed under AGPL-3.0, so anyone can read the code or run their own instance.
