Halloy is an IRCv3 chat client designed for real-time communication across multiple servers and networks. It implements modern protocol standards, including support for message tags, read markers, rich user metadata, and WebSocket connections.
The project distinguishes itself through integrated anonymity and deep interface customization. It features native Tor and proxy routing to hide the user's connection origin and provides a themed environment with configurable window pane layouts, keyboard aliases, and custom color schemes.
The client covers a broad range of capabilities, including channel and session management, bouncer integration, and automated connection tasks. Messaging features include infinite-scroll history retrieval, regular-expression message filtering, and the ability to execute local system shell commands directly from the interface.
Users can manage application settings and visual themes via configuration files that support signal-based reloading without requiring a restart.
