Same substrate. Different sentence.
Both products sit on libghostty-vt. Superlogical says mux for all work. 1SessionTool says own the session layer on your box, stay useful alone, and keep the studio as one-click edges.
Superlogical is building a terminal multiplexer on libghostty-vt with web and native clients, native scroll, and a larger thesis: a multiplexer for all work. As of September 2026 it is in early public development with a waitlist.
Where they win. People who want that team's multiplexer and the 'mux for all work' thesis, and who are fine waiting on their public release.
The difference. We refuse Superlogical's category line. 1SessionTool is the session layer on a box you own, for any CLI, with a studio compass (1DevTool, 1NetworkTool, ServerCompass) on the edges. We do not replace Ghostty. We do not mux all work.

Are you the same product?
No. We share a VT library. Superlogical's public line is a multiplexer for all work. 1SessionTool's locked jobs are persist, attach, spawn, plug in your server, and phone as glass.
Why mention them at all?
Because they set the category people will compare us against. The honest move is to name the difference instead of pretending the category is empty.
