    ambianic/peerfetch: Peer-to-peer HTTP over WebRTC.

    Peer-to-peer HTTP over WebRTC allows secure, direct access from web browsers to edge devices behind firewalls without needing custom VPN setups, cloud intermediaries, dynamic DNS, or custom firewall rules. It's safe to run in application space and supports end-to-end encryption. Currently available in JavaScript and Python, this approach supports various applications like private home security cameras, IoT device communication, personal web apps, and federated learning.
