HashiCorp cofounder Mitchell Hashimoto has launched Superlogical, a startup developing a server-side terminal multiplexer intended to make persistent programming sessions faster and more reliable. The company argues that conventional tools such as tmux, Zellij and GNU Screen duplicate terminal data and continually reconcile local and remote states, creating avoidable delays; its approach could also provide a foundation for more durable AI-agent work sessions.

Superlogical will build on libghostty, extracted from Hashimoto’s GPU-powered Ghostty terminal emulator. Under its design, the server retains a session’s state while clients send input and handle rendering and scrolling locally, allowing users to disconnect and resume work later without network round trips for every interaction. Hashimoto has disclosed few further plans, though observers speculate the technology could evolve into an AI-native layer for managing work across systems.
