What each one is
Flat.social is a browser-based platform for online meetings and events in which guests move around a virtual space as avatars and hear people nearby (spatial audio). Gender reveal is one of its use cases. Per its page, the host places a billboard with the answer in the middle of the room, hidden until reveal time; guests pick Team Pink or Team Blue, mingle, and gather at center stage while the host runs a countdown.
Diaper Reveal is a free online gender reveal game built only for this moment. Guests join by link or 6-letter code, play a short race and quiz, and the sealed result is revealed live. See how an online gender reveal works.
