Buzzcut – Make Your Apartment Buzzer Smart

Hacker News

Most apartment and condo buildings still rely on phone-based intercom systems. A visitor buzzes, your phone rings, and you press 9 to let them in. But if you miss the call or aren't home, you're out of luck. There's no easy way to grant remote access or see who’s coming and going. 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.
