peerfetch

Peer-to-peer HTTP over WebRTC. Implements an http client wrapper (similar to HTML fetch) and a corresponding server side HTTP proxy over WebRTC DataChannel. Allows direct secure access from a web browser to edge devices (IoT or servers) hidden behind a firewall.

Highlights:

• Excutes in safe application space (no sudo)
• End to end encryption
• No custom VPN setup needed
• No cloud middleman for data tunneling
• No dynamic DNS service required
• No custom firewall rules required
• Programming language agnostic. (Currently available in JavaScript and Python)

Hands-on Workshop

Here is the recording of a peerfetch workshop hosted by Python Austin.

Use cases:

• Direct user access from a web app to private home security camera without sharing footage with a cloud provider.
• IoT device mesh with direct p2p communication.
• Personal web apps can share data directly (files, notes, photos) only with the end user without exposing a public IP address.
• Federated learning - ML models can train on local user data and share learned states directly with each other without a centralized model aggregation server.
