About Gigas
A free, serverless platform for live multiplayer quizzes.
Gigas lets anyone build a quiz, host a live game on one screen, and have a room full of players join instantly from their phones, tablets, or laptops. It is designed to be fast, free, and require no downloads — everything runs in a normal web browser. Whether you are a teacher running a class review, a team lead breaking the ice in a meeting, or a friend hosting trivia night, Gigas gives you a Kahoot-style live game without the cost.
How it works under the hood
Most live-quiz tools route every player’s answers through a central server. Gigas does it differently: once a game starts, devices talk to each other directly using WebRTC DataChannels — the same peer-to-peer technology used by video-calling apps. A small signaling server is only used briefly, at the very beginning, to help the host and players find one another and open a connection. After that, the questions, answers, and scores flow straight between the host’s device and the players’ devices.
This peer-to-peer design keeps the platform lightweight and inexpensive to run, which is exactly why it can stay free. It also means the host keeps control of the game: if the host closes their tab, the room closes with it.

Why it’s free
Because games run peer-to-peer, Gigas does not need expensive real-time servers to relay gameplay. That keeps running costs low and lets us offer the core experience for free. You can read how we handle your information in our Privacy Policy, and the rules of use in our Terms of Service.
