Cloudflare Quick Tunnels puts your localhost on the internet with one command
Cloudflare Quick Tunnels offer a free, instant way to expose a local web server or API to the internet. With no account, configuration, or exposed ports, a single command creates a secure HTTPS URL on Cloudflare's global edge network, complete with automatic DDoS protection. The service works with any stack and is ideal for sharing previews with teammates, design reviews, or automated QA.
One command and you're live. No account creation, no configuration files, no waiting.
