# Imgfloat

A Spring Boot overlay server for Twitch broadcasters and their channel admins. Broadcasters can authorize via Twitch OAuth and invite channel admins to manage images that float over a transparent canvas. Updates are pushed in real time over WebSockets so OBS browser sources stay in sync.
