Starkomand vs Zeron.
Zeron is open source and free: one fast native window, in tabs, that drives Claude Code, Codex and the rest through their own protocols, with a live branch diff beside each chat and your sessions following you to every machine you sign in. Starkomand keeps each CLI’s own screen in a real terminal on a Mac canvas, and puts recaps, diagrams, briefs, voice and issue notes around it.

Which one.
Pick Zeron if

the CLI’s own screen, flags, slash commands and permissions matter to you, you want every agent laid out on one canvas instead of in tabs, or you want recaps, diagrams, briefs, voice and issue notes beside the windows.
