Quick Tunnels
Start a tunnel
Now with JSON output for coding agents

Localhost,
meet the Internet.

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

335+ CITIES~3S TO URL0 PORTS OPENEDFREE

Your laptop stays private.
The URL goes everywhere.

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 outputHostname, edge, and health as JSON on stdout — no regex on logs.
02
Webhook-readyPoint Stripe, GitHub, or your own callbacks at a live URL instead of fixtures.
03
Ephemeral by designThe tunnel dies with the process. Nothing to revoke, nothing to clean up.
