Mitchell Hashimoto Launches Superlogical to Build a Terminal Multiplexer for Humans and Agents, With Durable Sessions and Live Sharing Built In
On July 29 the creator of Vagrant, Terraform, and Vault announced a new company whose first product is a terminal multiplexer that keeps terminal blocks inside a long-lived session you can close, reconnect to from another device, and resume exactly — reachable via web and native macOS/iOS, with live session sharing from day one. The stated ambition is 'a multiplexer for all work' that unifies interactive development, automated processes, and production systems into a durable session that can 'expose structured data and actions, preserve history, and be driven by software while remaining visible and controllable by people,' explicitly serving coding agents and background jobs alongside humans. It builds on Ghostty's MIT-licensed libghostty while Ghostty stays a non-profit with unchanged governance, and the announcement is pointedly hand-written — 'No AI! Hand-written, real, and authentic.' For anyone orchestrating many agent sessions, this is the most credible attempt yet to make the terminal the substrate rather than a scrollback buffer; the HN thread drew 725 points and 425 comments.
