Quassel

Quassel is a German open-source software project best known for Quassel IRC, a modern, distributed Internet Relay Chat client designed to stay online around the clock. By separating a lightweight core that connects to IRC networks from one or more graphical or console clients, the suite lets users resume the same session from any desktop or mobile device without losing backlog, highlights, or private messages. Typical deployments include a headless core on a VPS, home server, or NAS, while laptops, workstations, and Android handsets act as remote clients; alternatively, a monolithic “standalone” build bundles both layers for quick personal use. The cross-platform C++/Qt codebase supports SSL/TLS encryption, SASL authentication, Blowfish encryption scripts, granular notifications, searchable backlog storage via SQLite or PostgreSQL, and flexible dockable interface layouts comparable to those found in commercial chat clients. Quassel therefore appeals to open-source developers, system administrators, and privacy-minded communities who require persistent, secure group communication without relying on proprietary cloud services. QuasselIRC and related tools are available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always providing the latest upstream release and allowing batch installation alongside other applications.
