Buzzcut turns these buzzers into smart access systems. It lets you unlock your building door from anywhere, share temporary access links with guests or delivery drivers, set auto-unlock rules during certain times, and keep a log of buzz-ins. No hardware changes are needed—just link your buzzer to a virtual number managed by the app.

It’s built with Flutter (iOS and Android support), a Python backend, Firebase, Twilio for virtual numbers, and RevenueCat for subscriptions. Group access control makes it easy to share access with roommates or family members.

This started as a solution to a personal problem and is now being tested in a few buildings in Toronto. Still early, but looking for feedback, testers, and ideas.

Would love to hear what you think.
