Radius

Radius turns any internet connection into a pay-as-you-go hotspot.

A host shares their internet. A guest joins the Wi-Fi, picks a pass (1 day €1, 1 week €5, 1 month €20), pays by card in euros, and is online for exactly as long as the pass lasts. The host keeps about 90%.

Why: I had no Estonian ID, so I couldn't get my own internet contract. Anyone sharing a connection, and anyone who needs one, hits the same wall.

How it works

• The host signs up and Radius creates their three passes automatically, each with a 90% payout split.
• On Start sharing, the host's machine acts as a router with a locked door: unpaid devices can only reach the payment page.
• The guest pays on a Creem checkout page. Our server confirms the payment with Creem, then the device is let online until the pass ends.
• The host sees earnings, passes sold and guests online live on their dashboard, and can disconnect a guest at any time.

Built with: Flutter (macOS), Supabase (auth, database, edge functions) and Creem (checkout and payout splits).

Status: hackathon prototype built for Built for Baltics Hack. The laptop stands in for the router; the product is a router box a host plugs in.
