Mitchell Hashimoto launches Superlogical with a server-side terminal multiplexer

Mitchell Hashimoto's new company Superlogical opens with a server-side terminal multiplexer built on libghostty, holding session state on the server SSH-style while a local client handles rendering and scrolling without waiting on the network. That removes the duplicated input and local-versus-remote reconciliation Hashimoto blames for tmux, Zellij and GNU Screen being slow, so a persistent session can span multiple terminals without the lag tax. Gergely Orosz reads the deliberately narrow starting point as groundwork for an AI-native 'agentic operating system.'

Persistent sessions could be just the beginning

The Register

Why this matters

→ Removes network latency from terminal multiplexing, solving a decades-old performance problem.
→ Server-side session state enables persistent work across devices without sync overhead.
→ Positions terminal multiplexing for AI agents to control.
