Quassel IRC

Quassel IRC is a modern, cross-platform IRC client built around a distributed architecture. A central Quassel Core maintains persistent IRC connections and history, while one or more clients can attach and detach from anywhere.

Key Features

• Distributed "core + client" design for always-on IRC connectivity
• Multi-client access to the same core (desktop and mobile clients can share state)
• Backlog and chat history stored in a database for fast retrieval
• Supports modern IRC capabilities (including many IRCv3 features)
• User management on the core (multiple users can be hosted on one core)
• Optional integrations such as Prometheus metrics export and HAProxy protocol support

Use Cases

• Run a personal IRC bouncer-like setup with a full graphical client experience
• Keep IRC connections persistent on a server and attach from multiple devices
• Maintain searchable, centralized chat history for teams or communities

Quassel IRC is well-suited for users who want the convenience of a bouncer with a richer client experience and multi-device continuity, while keeping control over where connections and history are stored.
