Cloudflare Quick Tunnels

Cloudflare Quick Tunnels

Now with JSON output for coding agents 现在支持为编程智能体(Coding Agents)提供 JSON 输出。

Localhost, meet the Internet. Localhost,连接互联网。

One command turns the server on your laptop into a public, encrypted URL on Cloudflare’s edge. No account. No DNS. No open ports. 只需一条命令,即可将你笔记本电脑上的服务器转换为 Cloudflare 边缘节点上的公共加密 URL。无需账户,无需 DNS,无需开放端口。

$ cloudflared tunnel --url http://localhost:8000

335+ CITIES | ~3S TO URL | 0 PORTS OPENED | FREE 335+ 个城市 | ~3秒生成 URL | 0 端口开放 | 免费

Your laptop stays private. The URL goes everywhere. 你的笔记本电脑保持私密,而 URL 可以通达全球。

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. cloudflared 会向最近的边缘节点建立仅限出站的连接。发送到你隧道 URL 的流量将通过 Cloudflare 网络传回你的机器——全程加密、经过 DDoS 过滤,且绝不触碰任何入站端口。

01 · YOUR MACHINE localhost:8000 Any framework, any port. Nothing inbound. 01 · 你的机器 localhost:8000 任何框架,任何端口。无入站流量。

02 · CLOUDFLARE EDGE quiet-marble-otter-canyon.trycloudflare.com TLS | DDoS filter | Anycast | 335+ cities 02 · Cloudflare 边缘节点 quiet-marble-otter-canyon.trycloudflare.com TLS | DDoS 过滤 | Anycast | 335+ 个城市

03 · ANYONE, ANYWHERE Teammates & agents | Browsers, webhooks, eval harnesses. 03 · 任何人,任何地点 团队成员与智能体 | 浏览器、Webhook、评估工具。

~3s Instant setup No sign-up, no config file, no waiting on DNS. The URL prints before your coffee cools. ~3秒即时设置 无需注册,无需配置文件,无需等待 DNS 生效。在你的咖啡变凉之前,URL 就已经生成了。

0 Ports opened Outbound-only. Automatic HTTPS and edge DDoS mitigation come with every tunnel. 0 端口开放 仅限出站。每个隧道都自带自动 HTTPS 和边缘 DDoS 防护。

335+ Cities on the edge A reviewer in Tokyo and a webhook in Frankfurt both hit the edge nearest them. 335+ 个边缘城市 东京的审核人员和法兰克福的 Webhook 都能连接到离他们最近的边缘节点。

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. 为智能体时代而生 你的智能体需要的是 URL,而不是笔记本电脑。编程智能体在循环中进行构建、测试和审查。Quick Tunnel 为每一个循环提供了一个真实、可访问的地址——无论是用于截图服务、Webhook、评估工具,还是供人类点击查看。

01 Structured output Hostname, edge, and health as JSON on stdout — no regex on logs. 01 结构化输出 主机名、边缘节点和健康状态以 JSON 格式输出到标准输出(stdout)——无需对日志进行正则匹配。

02 Webhook-ready Point Stripe, GitHub, or your own callbacks at a live URL instead of fixtures. 02 Webhook 就绪 将 Stripe、GitHub 或你自己的回调指向一个实时 URL,而不是使用模拟数据(fixtures)。

03 Ephemeral by design The tunnel dies with the process. Nothing to revoke, nothing to clean up. 03 设计即瞬时 隧道随进程结束而销毁。无需撤销权限,无需清理。
