High-performance terminal-style YouTube live chat interface with custom themes, message pruning, and power-user controls.
Terminal Chat is a high-performance, terminal-inspired replacement for the standard YouTube Live Chat interface. Designed for power users and high-density environments, it prioritizes speed, customizability, and efficient screen real estate management. Handles 5000+ messages without a hiccup. The script transforms the often-cumbersome native chat into a lightweight, themeable console featuring advanced message pruning to maintain browser performance during intense live events.
Geometry engine, which allows the terminal to function as a native component of the YouTube sidebar or as a free-floating, unsnapped window. This system includes independent memory for both states, ensuring that dimensions and coordinates remain persistent across page refreshes and different video sessions. Built with cross-browser stability in mind, it utilizes a security-first approach to DOM injection and provides a suite of administrative controls, including user muting, message filtering, and integrated emoji support, all within a unified, minimalist aesthetic.
