Requires your own computer — Windows 10/11 or macOS — running the wmux daemon. Nothing runs in the cloud and there is no account. Your coding agents keep working when you walk away from the desk. wmux is how you stay in the loop. An agent that needs permission to run a command stops and waits. wmux puts that question on your phone — on the lock screen, answerable without unlocking — so a run that used to sit idle until you came back keeps going.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 5 screenshots above are wmux - Workspace for AI agents's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: wmux - Workspace for AI agents runs a dark set with one background colour (#141414) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #042C8C, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
