July 19, 2025 · Knight Galloping Wild · 1907 views

Deploy your own subscription conversion tool in the cloud, supporting SingBox / Clash / V2Ray / Xray with custom rules — completely free forever!

🔥 Why Choose Sublink Worker + Cloudflare Worker?

Traditional subscription conversion tools usually require you to provide your own server, which comes with high maintenance costs and unstable network issues. Sublink Worker innovatively leverages Cloudflare Worker, a global serverless platform, to deliver:

• ✅ Zero server cost: Runs entirely on the Cloudflare edge network
• ⚡ Global lightning-fast access: Accelerated by Cloudflare's CDN nodes
• 🔒 Secure & reliable: Built-in DDoS protection and HTTPS
• 🚀 One-click deployment: No complex environment setup — ready in 5 minutes
• 💡 Fully customizable: Configure rulesets and proxy groups however you like

Below is the step-by-step deployment tutorial.

📥 Step 1: Fork the Project to Your GitHub

Visit the project repository: https://github.com/7Sageer/sublink-worker

Click the Fork button in the top-right corner.

🚀 Step 2: Deploy to Cloudflare Worker

After forking, click the blue "Deploy to Cloudflare" button at the top of your forked repository.

Note: Make sure you are logged into Cloudflare and have linked your GitHub account beforehand. New bindings need to refresh permissions — follow the prompts accordingly.

On the deployment configuration page:

• Import repository → Select your forked repo
• Configure your application → Project name: sublink-worker (do not modify unless deployment fails)
• Modify the deploy command to: npm run deploy
• Click Deploy

🌐 Step 3: Access Your Subscription Conversion Service

Once deployed successfully:

• Default access URL: https://your-worker-name.your-cloudflare-account.workers.dev
• Use a custom domain: Go to Worker → Triggers → Add → Custom Domain → bind your own domain.

🎨 Using the Sublink Web Interface

Open your Worker URL, and you will see the following:

Core Operations

• Import subscription:

  • Supports Base64-encoded HTTP/HTTPS subscription links
  • Or directly paste single node links such as SS / Vmess / VLESS / Trojan
• Select client: Sing-Box / Clash / Xray / V2Ray, etc.

• Customize rules:

  • Use preset rulesets (e.g., GFWList split-routing)
  • Or define your own geo-site, geo-ip, and domain-suffix policies

• Generate subscription:

  • Get the converted subscription link
  • Optionally generate a short link

⚡ Advanced Usage Examples

Generate a subscription directly via API

curl -X POST "https://your-worker.dev/convert" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://original-sub.com/link",
    "target": "clash",
    "config": {
      "ruleset": ["geosite:geolocation-!cn", "ip-cidr:8.8.8.8/32"]
    }
  }'

Supported Protocol List

❓ Troubleshooting

• Short link feature not working?
  → Check whether you have created a KV namespace and bound it to the Worker.
• Deployment error: npm not found?
  → Make sure the deploy command is set to: npm run deploy
• How to update to a new version?

# Enter your forked local repository
git remote add upstream https://github.com/7Sageer/sublink-worker
git pull upstream main
# Push updates to your GitHub repo — Cloudflare will auto-redeploy

💡 Best Practices

• Enable an access password: Set the ACCESS_TOKEN environment variable to prevent abuse.
• Bind a custom domain: Avoid the risk of workers.dev domains being blocked.
• Update rulesets regularly: Subscribe to the GitHub repo for the latest security updates.
• Pair with a client: Clash configuration example below.

# Clash configuration example
proxies:
  - name: "My_Server"
    type: vmess
    server: your-server.com
    port: 443
    uuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    alterId: 0
    cipher: auto
    tls: true
    skip-cert-verify: true
    network: ws
    ws-path: /your-path
    ws-headers:
      Host: your-server.com
