A phone-app style chat experience for Minecraft, powered by Skija.
AtomChat replaces the vanilla chat screen with a phone-style panel for public chat, private conversations and rich media. Its interface is vector-drawn with Skija and does not depend on vanilla chat textures.
Client required · Server optional. A server install adds hosted media, shared reactions, profile sync and server-provided content.

With server hosting enabled, images are stored on that server and kept according to its retention settings. Otherwise uploads use uguu.se; those links expire after roughly three hours. Images upload only when you choose, paste or drag a file, but recipients may save or forward them. Chat history may also be saved locally by players who enable it. Do not send sensitive content.
