Mitchell Hashimoto Founds Superlogical, Starting With a Terminal Multiplexer

Mitchell Hashimoto is founding Superlogical, whose first product is a terminal multiplexer built on the same MIT-licensed libghostty components available to everyone — an announcement and a hiring post, with no ship date or product details. Ghostty stays under the non-profit he donated it to in 2025, license and governance unchanged, and Superlogical commits to upstreaming shared terminal work to libghostty.

I found a problem I wanted to spend years working on, a scope that required a team, and people I wanted to build it with.

Why this matters

→ Terminal multiplexer market gets a new entrant from experienced builders.
→ Ghostty remains non-profit; Superlogical uses its open components commercially.
→ Signals renewed interest in terminal infrastructure as developer tooling evolves.

Tmux gets a rival
