PetCam

PetCam is a peer-to-peer pet-watching app. Point a phone at the cat, open the link on another device, and the video streams directly between them. No cloud recording, no per-month fee, no Big Camera Company knowing what your dog gets up to.

Why I built it

A short note on the original itch — commercial pet cameras felt overbuilt and under-private. I wanted something I could set up in two minutes and trust to not phone home.

How it works

• A signalling Worker brokers the WebRTC handshake; no media touches the server.
• TURN fallback only when both peers are behind symmetric NAT.
• TLS-only, room-keyed; URLs are single-use.
