It operates as a server application that manages connections between IRC clients, allowing users to join channels and exchanges ลอง」 exchange messages. The software is deployed on server environments and supports a wide range of operating systems including Linux, macOS, and Windows. It provides the backend infrastructure necessary to maintain persistent chat rooms and direct messaging capabilities for large numbers of concurrent users.

Administrators use a highly configurable configuration file to manage the server environment and define network behavior. The software is architecture-agnostic, meaning it runs on x64, x86, and arm64 systems. It is used by network operators to build and maintain chat communities with a focus on security and modularity, ensuring that the server can be tailored to specific community needs through its extensive set of options.
