Beyond HTTP: Exposing WebRTC and Local Game Servers via UDP Tunnels
IT InstaTunnel Team Published by our engineering team For the better part of the last decade, developers have relied on localhost tunneling services to expose local applications to the wider internet. Tools that generate a quick, temporary URL pointing straight to your machine’s port 3000 became indispensable for web developers building webhooks, OAuth flows, and REST APIs. But the development ecosystem of 2026 has outgrown that model. We are no longer just building stateless HTTP web applications. We are building real-time multiplayer game netcode, low-latency video streaming applications using WebRTC, and specialized IoT networks running protocols like CoAP and DTLS. The problem is that most legacy tunneling tools are strictly hardcoded for HTTP and TCP. When you try to route a connectionless protocol like UDP through a TCP-centric tunnel, you encounter massive overhead, latency spikes, and fundamentally broken application behaviour. This article explains why, walks through the...
