Why we picked it

For developers, this is a free and secure alternative to tools like ngrok, offering a built-in webhook feature that simplifies automated testing workflows.

Cloudflare's Quick Tunnels product now offers a 3-second URL generation, zero open ports, and is completely free. The service allows local services to be made publicly accessible via a secure URL (*.trycloudflare.com) without registration, DNS configuration, or port opening. It uses a client that initiates outbound connections to Cloudflare's edge nodes, ensuring no inbound ports are opened on the user's machine. The traffic is routed through Cloudflare's global network (335+ cities) with built-in TLS encryption, DDoS protection, and Anycast for low latency. A key feature is its design for the AI agent era, including structured JSON output for easy parsing by coding agents, webhook readiness for Stripe and GitHub integrations, and automatic tunnel termination when the process ends.

try.cloudflare.com 3 秒生成 URL、0 个开放端口、完全免费 @Cloudflare 官方 Quick Tunnels 产品页,一句话定位:“Localhost, meet the Internet”,一条命令,把你电脑上跑的本地服务变成一个公网可访问的加密 URL(*.trycloudflare.com),全程无需注册账号、无需配置 DNS、无需开放任何端口。 核心机制(为什么它安全且简单) 传统做法要在路由器上开端口、做端口映射,暴露攻击面;Quick Tunnels 反其道而行: · cloudflared 客户端只发起出站连接,连到最近的 Cloudflare 边缘节点,你的机器不开任何入站端口; · 流量经 Cloudflare 全球网络(335+ 城市)中转,天然附带 TLS 加密、DDoS 过滤和 Anycast 就近接入; · 整个链路是:本地服务(任意框架、任意端口)→ Cloudflare 边缘 → 访问者(浏览器、webhook、测试工具)。 一个值得注意的亮点:为 AI Agent 时代设计 "built for the agent era",这是它区别于 ngrok 等同类工具的叙事重点。三个针对性设计: 1. 结构化输出:返回 JSON 格式的主机名、边缘节点和健康状态,便于程序(尤其是 coding agent)解析,而不是靠正则去抓终端文本; 2. Webhook 就绪:Stripe、GitHub 等回调可以直接指向这个真实 URL,让自动化测试闭环跑通; 3. 临时性:"The tunnel dies with the process":进程结束隧道即销毁,无需撤销令牌或清理资源。这对无人值守的自动化循环尤其友好,不会留下一堆遗忘的暴露端点。 使用方式 brew install cloudflared # 无需登录 # 本地跑起你的应用(任意技术栈,如 localhost:8000) cloudflared tunnel --url http://localhost:8000 把生成的 *.trycloudflare.com 链接发给任何人即可访问。 💬 1 🔄 1 ❤️ 2 👀 471 📊 2 ⚡
