About Pangolin is an open source, identity-aware tunneled reverse-proxy platform that lets you securely expose applications from any location without opening inbound ports or requiring a traditional VPN. It uses a distributed architecture of globally available nodes to route traffic through encrypted WireGuard tunnels, enabling devices behind NATs or firewalls to serve applications publicly via a central dashboard. Through the unified dashboard, you can manage sites and resources across your infrastructure, define granular access-control rules (such as SSO, OIDC, PINs, geolocation, and IP restrictions), and monitor real-time health and usage metrics. The system supports self-hosting (Community or Enterprise editions) or a managed cloud option, and works by installing a lightweight agent on each site while using the central control server to handle ingress, routing, authentication, and failover.
