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
- Downloads edgetunnel — fetches the worker code from GitHub (cmliu/edgetunnel, 30k+ stars)
- Generates credentials — creates UUID for VLESS authentication and admin password
- Deploys to Cloudflare Pages — not Workers, because Pages supports CNAME-based custom domains
- Registers a free domain — via DNSExit (free 2-year second-level domains like
*.linkpc.net)
- Configures DNS — creates CNAME record pointing subdomain to
*.pages.dev
- Binds custom domain — attaches the domain to the Cloudflare Pages project
- 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
| Resource | Free Quota | Impact on Proxy |
|---|
| Requests | 100,000/day | WebSocket connection = 1 request; messages free |
| Bandwidth | Unlimited | No egress fees — biggest advantage |
| CPU time | 10 ms/request | Proxy is I/O-bound, typically <3ms |
| Memory | 128 MB/isolate | Sufficient |
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

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)
