Overview

ETSi (Edge Topology Secure Intranet) is a sovereign P2P intranet platform that runs entirely within your corporate VPN or LAN. It requires no central server, no cloud account, and no internet connection.

What it does

ETSi discovers peers on your subnet, keeps a live mesh of who is connected and what they're hosting, and provides:

• A directory of all active peers on the network
• One-click static site hosting via an embedded Caddy server
• A built-in Chromium browser that resolves custom .etsi domain names
• Direct TCP peer-to-peer chat
• An optional portable MariaDB SQL daemon
• A zero-trust gateway proxy validating all inbound connections

How it works

On launch, ETSi performs a parallel scan of your entire subnet on port 9090, discovering any machines running ETSi. It then enters a gossip loop — every 10 seconds, each node shares its full peer list with a random known peer. This propagates network state across the entire mesh without any central coordinator.
