By the mid-2020s, the friction became untenable. As cybersecurity insurance premiums rose and IT departments tightened controls, the question for many engineering organisations shifted from “how do we tunnel?” to “can we tunnel without installing anything at all?” Enter the era of WebAssembly-native, in-browser tunnels — not a web dashboard bolted onto a local tool, but the tunnel itself born, compiled, a...
