ChatCube is the instant messenger built for the ULTRA OS ecosystem, powered by the UltraCanvas framework. Designed to bring people together regardless of which platform they use, ChatCube goes far beyond a simple chat client — it’s your unified communication hub.
Chat one-on-one or in groups, send files and images, use stickers, reply, forward, and edit messages — all within a clean, native interface that feels right at home on any desktop. ChatCube integrates directly with Telegram, and future support for IRC, Jabber, and more will make it the single app you need for all your conversations.
Security is built in from the ground up. All communication is encrypted over HTTPS, with secure token-based authentication and encrypted local storage — so your messages stay yours. A built-in screenshot tool, sound notifications, message search, and automatic reconnection on network loss ensure ChatCube keeps working even when conditions aren’t perfect.
Built on UltraCanvas, ChatCube inherits a fully native, hardware-accelerated rendering pipeline across Linux, Windows, and macOS — consistent, fast, and visually polished on every OS ULTRA OS supports.
ChatCube. One app. Every conversation.
