IRCCloud is an IRC (Internet Relay Chat) client that operates in-browser. It is designed to always be connected and able to receive messages, even when the user's browser is closed and their computer is offline. Users can access IRCCloud from multiple computers at once without confusing the service. The service's design focuses on unobtrusive function, and it doesn't use graphical emoticons.
The IRCCloud API allows users to access the service programmatically via REST calls. Only secure access is supported. The API is functional, but still under development. Its methods, responses, and message formats are subject to change at any time.
