catgirl is a lightweight IRC client for the terminal written by June McEnroe. It provides tab completion, nickname coloring, URL detection, message filtering, chat logging, and TLS support through libtls. catgirl follows a simple Unix philosophy and intentionally avoids features such as built-in multi-network support, automatic reconnection, and dynamic configuration. Multiple networks can be handled by running multiple instances in tmux(1), screen(1), or separate terminal windows. Homepage: https://git.causal.agency/catgirl
