As answered by people managing Foam and PanicMode.
PanicMode's answer:
PanicMode instantly replaces your screen with believable workspace overlays using a global shortcut. Instead of minimizing windows one by one, users can switch to a clean neutral workspace immediately and toggle back just as fast.
PanicMode's answer:
PanicMode focuses on speed, simplicity, and realism. It runs locally, activates instantly with a shortcut, and includes realistic workspace environments designed to feel natural instead of looking like a blank lock screen or generic privacy filter.
PanicMode's answer:
PanicMode is designed for people who work on laptops and want a fast way to temporarily cover personal, distracting, or sensitive content while working around others.
PanicMode's answer:
The idea came from those moments where you suddenly want to hide what is visible on your screen without awkwardly minimizing windows or switching desktops manually. PanicMode was built to make that action instant and effortless.
PanicMode's answer:
PanicMode is built using Tauri and React. The website and interactive browser preview are built with Next.js.
PanicMode's answer:
PanicMode is currently an independent product focused on early adopters and individual users.
