irt.io vs Playroom
Playroom is zero-setup and host-authoritative — great for quick party games, but there is no server authority, so one player’s machine is the source of truth.
irt.io has no host concept at all: the server is the only authority. A
builder who wants host-authoritative behavior expresses it in a few lines
(owner: firstJoiner in onJoin, reassign in onLeave) — so you get the
zero-setup on-ramp and a path to real authority without a rewrite.
