End-to-end encrypted, store-and-forward messaging that works with no tower, Wi-Fi, or server. A message hops device to device across everyone in between until it reaches its destination, confidential the whole way, even across relays you don't trust.
Binary spray-and-wait spreads a small copy budget across independent paths so the first to arrive delivers, and the cloud backbone holds messages for recipients who are offline. Built for events, field teams, remote communities, and response.
The same animations from the homepage, for Messaging. Tab through the situations and watch a sealed message find a way across the mesh.
Your browser is running the real Hop protocol: every node above is the actual hop-core, compiled to WebAssembly, carrying real encrypted messages. Only the devices and their radios are simulated.
