GoKawiilCloudflare's five-year-old Quick Tunnels feature goes viral for exposing localhost instantly
Developers on Hacker News and X recently rediscovered Cloudflare's Quick Tunnels tool, which lets anyone expose a local server to the internet with a single command—no account, DNS setup, or router configuration needed. The feature, built by a summer intern and shipped in 2021 under the Argo Tunnel lineage, generates a temporary public URL at trycloudflare.com that disappears once the process is stopped. Cloudflare recently refreshed its marketing for the tool, now pitching it for AI coding agents that need a reachable endpoint for locally running code.
