The company is building a server-side terminal multiplexer designed to be faster than existing tools like tmux, Zellij, and GNU Screen. Traditional multiplexers suffer from slow performance due to constant duplication of input and local/remote state reconciliation. Superlogical's approach uses libghostty as its foundation, keeping persistent session state on the server while delegating rendering and scrolling to a smart local client — similar to an SSH session but with richer capabilities. The company positions the terminal as a missing primitive for stateful work sessions that span machines, users, and AI agents, with speculation that it could evolve into an AI-native agentic operating system layer. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Superlogical and who founded it? Superlogical is a startup founded by HashiCorp cofounder Mitchell Hashimoto to build a server-side terminal multiplexer. It aims to replace tools like tmux, Zellij, and GNU Screen by eliminating client/server state duplication, building on libghostty, the extracted engine from the Ghostty terminal emulator that Hashimoto also created. _Developers tracking new infrastructure tooling from HashiCorp's founders can follow updates like this on daily.dev._ ### Why are traditional terminal multiplexers like tmux considered slow? Traditional multiplexers such as tmux, Zellij, and GNU Screen duplicate everything the user types and must constantly reconcile local and remote state, which introduces latency. Even pairing them with fast modern terminal emulators like Kitty, Alacritty, or Ghostty does not fix this because the bottleneck is architectural, not rendering speed. _Engineers weighing terminal workflow upgrades can track tooling comparisons like this on daily.dev._ ### What is libghostty and how does it relate to the Ghostty terminal emulator? Libghostty is a software library that Mitchell Hashimoto extracted from the core engine of Ghostty, the GPU-driven terminal emulator he built while at HashiCorp, so other developers and companies could build on it. Superlogical uses libghostty to create smart, high-functioning clients for its server-side terminal multiplexer. _Developers evaluating terminal infrastructure building blocks can follow projects like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@allinonetools** · 3 upvotes > **This sounds promising, especially if it makes remote sessions feel as responsive as local ones.** **@hemna** · 0 upvotes > Why is this even needed?
