Show HN: TunnelBuddy Demo: HTTPS P2P proxy using WebRTC [video] (opens in new tab)

Here is a demo of TunnelBuddy: an Electron app which lets one trusted friend share their internet connection with you over a P2P HTTPS proxy built on WebRTC.

It’s in the same spirit as uProxy, but instead of relying on deprecated browser socket APIs, it uses Electron + Node.js to run a local HTTPS proxy and WebRTC data channels between two peers.

There’s no signup and no accounts: the person sharing their connection generates a one-time code and sends it to their friend, who pastes it in to connect. Hopefully that gives some old-school TeamViewer vibes to anyone watching.

It’s free to use; there’s an optional donation button in the app, but no ads or upsells.

Happy to answer any questions about how it works, security model, trade-offs vs VPNs/Tailscale, etc.
