Cloudflare has introduced Quick Tunnels, a service that allows users to create a public, encrypted URL for their local server with just one command, without requiring an account, DNS, or open ports. The service uses an outbound-only connection to Cloudflare's edge network, providing automatic HTTPS and DDoS mitigation. This allows developers to share their local work with others, such as teammates or webhooks, without exposing their laptop to the internet. The service is designed for ephemeral, encrypted tunnels and can be used for previews, CI, webhooks, and agents.
