Classroom management
A macOS tool for teachers — watch student screens, share your own, push focus wallpapers, run approved commands. All over the school's own network. Open source.
The teacher's view
The admin console lists every device that has joined today — online status, screen thumbnails, one-click sharing and focus controls.
What it does
Watch live student screens and broadcast your own, over the LAN. Classroom content never touches the cloud.
Lock every student Mac onto one image in one click, release it when the lesson moves on.
Whitelisted commands run only with the teacher's explicit decision. Keys stay on the Mac.
Cut every student Mac off the internet while the classroom LAN keeps working — set a duration, or leave it on until you release it. A discreet on-screen indicator, with no student-facing dialogs.
