One command turns the server on your laptop into a public, encrypted URL on Cloudflare's edge. No account. No DNS. No open ports. $ cloudflared tunnel --url http://localhost:8000 Copy  (index.html#how) See how it works ↓  335+ CITIES ~3S TO URL 0 PORTS OPENED FREE    Your laptop stays private.The URL goes everywhere. (https://github.com/cloudflare/cloudflared) cloudflared opens an outbound-only connection to the nearest edge location. Traffic to your tunnel URL rides Cloudflare's network back to your machine — encrypted, DDoS-filtered, and never touching an inbound port.  01 · YOUR MACHINE localhost:8000 Any framework, any port. Nothing inbound.     02 · CLOUDFLARE EDGE quiet-marble-otter-canyon.trycloudflare.com TLS DDoS filter Anycast 335+ cities      03 · ANYONE, ANYWHERE Teammates & agents Browsers, webhooks, eval harnesses.    ~3s Instant setup No sign-up, no config file, no waiting on DNS. The URL prints before your coffee cools.  0 Ports opened Outbound-only. Automatic HTTPS and edge DDoS mitigation come with every tunnel.  335+ Cities on the edge A reviewer in Tokyo and a webhook in Frankfurt both hit the edge nearest them.       BUILT FOR THE AGENT ERA Your agent needs a URL, not a laptop. Coding agents build, test, and review in loops. A Quick Tunnel gives every loop a real, reachable address — for a screenshot service, a webhook, an eval harness, or a human who wants to click around. 01 Structured output Hostname, edge, and health as JSON on stdout — no regex on logs.   02 Webhook-ready Point Stripe, GitHub, or your own callbacks at a live URL instead of fixtures.   03 Ephemeral by design The tunnel dies with the process. Nothing to revoke, nothing to clean up.         agent-runner — zsh  $          Install. Run.
