BuzzIn lets apartment tenants pre-authorize access to their building intercom. Set a time window and the door opens automatically for your guest — no phone call, no interruption. In an important meeting when your UberEats arrives? Hosting a party and want guests to walk right in? BuzzIn handles it. Works with any existing intercom that calls a phone number. Setup takes minutes, no hardware required.
I built BuzzIn because I kept missing deliveries. I'd be in a meeting or a shower and my intercom would ring, and I’d miss it. Countless UberEats orders were left cold downstairs, and my friends had to impatiently wait to be let in.
I wanted a way to say "I'm expecting someone between 3:15 and 3:45 — just let them in" without any intervention on my part.
The insight was that most intercoms just call a phone number — so if you replace that number with a Twilio number, your software can answer the call and decide what to do.
I built the entire thing using Claude Code as a complete beginner to coding. The stack is Next.js, Supabase, and Twilio. What started as a personal tool for my own unit evolved into a multi-tenant app where anyone can sign up, and be up and running in under 3 minutes — no hardware, no technical knowledge required.
