Knocky turns a printed QR code into a web doorbell for homes and apartments. Visitors scan it, share their location, and can ring or start a temporary chat only when they are physically near the address. Owners receive real-time notifications and can reply with text, images, or audio. No app is required for visitors, and precise location data is used only for the proximity check.
I built Knocky to replace apartment intercoms and exposed phone numbers with something simple: a QR code on the door. The hard part was preventing remote abuse, so Knocky verifies that the visitor is actually near the address before enabling the ring or temporary chat. Visitors need no app, owners can respond in real time, and location is used only for the proximity check. I’d love feedback on the onboarding and whether you would use this at a home, apartment, office, or rental.
