Deploy a free VLESS proxy/VPN node on Cloudflare Pages using edgetunnel. Automates code download, UUID generation, Pages deployment, free domain registration (DNSExit), DNS configuration, custom domain binding, and client setup for Shadowrocket/v2rayN/Clash. Uses Cloudflare Pages (not Workers) because Pages supports CNAME-based custom domains from any DNS provider, avoiding the need to host DNS on Cloudflare.

Cloudflare Proxy (cf-proxy)

Deploy a free VLESS proxy node on Cloudflare Pages + edgetunnel, with WebSocket over TLS through Cloudflare's global CDN.

When to Use This Skill

  • Setting up a free proxy/VPN node on Cloudflare
  • Deploying edgetunnel to Cloudflare Workers or Pages
  • Building a VLESS/Trojan/Shadowsocks proxy on Cloudflare's free tier
  • Configuring a custom domain for a Cloudflare proxy to bypass SNI blocking
  • Managing, updating, or troubleshooting an existing Cloudflare proxy node
  • Registering a free domain for proxy use

What This Skill Does

  1. Downloads edgetunnel — fetches the worker code from GitHub (cmliu/edgetunnel, 30k+ stars)
  2. Generates credentials — creates UUID for VLESS authentication and admin password
  3. Deploys to Cloudflare Pages — not Workers, because Pages supports CNAME-based custom domains
  4. Registers a free domain — via DNSExit (free 2-year second-level domains like *.linkpc.net)
  5. Configures DNS — creates CNAME record pointing subdomain to *.pages.dev
  6. Binds custom domain — attaches the domain to the Cloudflare Pages project
  7. Verifies and configures — tests the node and provides client configuration

How to Use

Basic Usage

Help me set up a free Cloudflare proxy node

/cf-proxy

With Specific Requirements

Deploy a VLESS proxy on Cloudflare using my domain example.com

Fix my Cloudflare proxy — Shadowrocket can't connect

Architecture

Client (Shadowrocket / v2rayN / Clash)
  ↓ VLESS over WebSocket over TLS (port 443)
Custom Domain (CNAME → *.pages.dev)
  ↓
Cloudflare CDN (global edge)
  ↓
Cloudflare Pages Function (edgetunnel _worker.js)
  ↓ TCP outbound
Target Website

Why Pages Instead of Workers?

  • workers.dev domains are blocked at the TLS SNI layer by some firewalls
  • Workers custom domains require DNS hosted on Cloudflare — not viable for free domains
  • Pages supports CNAME-based custom domains from any DNS provider — the key advantage

Cloudflare Free Tier Limits

ResourceFree QuotaImpact on Proxy
Requests100,000/dayWebSocket connection = 1 request; messages free
BandwidthUnlimitedNo egress fees — biggest advantage
CPU time10 ms/requestProxy is I/O-bound, typically <3ms
Memory128 MB/isolateSufficient

Known Limitations

  • No UDP — only TCP over WebSocket; cannot proxy games, VoIP
  • Speed varies — 5-50 Mbps depending on CDN routing; not for low-latency use
  • 100K daily request cap — sufficient for daily browsing; heavy use may hit limit
  • Custom domain SNI may be blocked — domain rotation may be needed

Example

User: "帮我搭建一个 Cloudflare 代理节点"

Output: Skill walks through the full 7-phase setup interactively — collecting Cloudflare credentials, generating config, deploying to Pages, registering a free domain if needed, configuring DNS, binding the custom domain, and providing the final VLESS connection URI for the user's proxy client.

Tips

  • Always use a subdomain for CNAME records (e.g., vless.example.com), never the root domain — a root CNAME destroys the zone's SOA/NS records
  • The admin panel at https://your-domain/<admin-password> provides ready-to-scan QR codes for mobile clients
  • If speed is insufficient, try different Cloudflare CDN IP addresses as the proxy endpoint
  • Keep usage low-profile for personal use to avoid Cloudflare ToS issues

Requirements

  • Node.js 18+
  • GitHub CLI (gh)
  • Cloudflare account (free tier)
  • A domain (free via DNSExit, or bring your own)
