Dev who gave HashiCorp its name returns with a faster terminal multiplexer
Persistent sessions could be just the beginning
HashiCorp co-founder Mitchell Hashimoto has unveiled a new startup, Superlogical, aimed at developing a server-side terminal multiplexer with enhanced speed and efficiency. Traditional multiplexers like tmux, Zellij and GNU Screen struggle with slow performance due to duplicating user input and reconciling local and remote states.
Hashimoto believes that a fundamental primitive is missing in today's computer architecture - a stateful session for work that can span machines and users. His solution, Superlogical, builds upon his earlier project Ghostty, a modern terminal emulator known for its speed and features. Superlogical plans to utilize libghostty, a library extracted from Ghostty, to create a client/server system that enables persistent sessions.
Users can disconnect and reconnect, while a smart client manages rendering and scrolling locally. The company aims to build a scalable and standardized system for managing work sessions, potentially leading to the development of an "AI-native 'agentic operating system'" as speculated by Pragmatic Engineer Substack author Gergely Orosz.
