About Periph
Independent software for macOS
Periph is a Mac app that turns the edge of your screen into a quiet signal. When a meeting is about to start, Claude Code finishes a task, a sale comes in or your mic is live, the border of your display lights up in a colour and motion you learn to recognise from the corner of your eye. No banners to dismiss, no tabs to check.
Why it exists
Notifications pull you out of your work to read them. Notch apps only work on a MacBook's built-in screen. We wanted something that works on any display, never covers what you're doing, and tells you what happened without words. That became Periph.
Who makes it
Periph is built and supported by an independent developer. There's no venture funding and no team of salespeople: the person who answers your email is the person who writes the code. Every message to [email protected] gets a personal reply, usually within one business day.
