How It Works

Vercel

Vercel's Edge Functions support custom deployment regions. By querying DNS records through DoH, we can obtain global DNS resolution results. Theoretically supports 18 countries or regions.

Cloudflare

Cloudflare Workers are deployed globally. By accessing Workers in specific regions and using DoH to query DNS records, we can obtain global DNS resolution results. Theoretically supports 120+ countries and 330+ cities.

Deployment

Supports deployment to either Vercel or Cloudflare, independently.

Deploy to Vercel

1. Fork the project to your GitHub
2. Create a new project on Vercel
3. Select the DNS.Surf project and Next.js framework
4. Save and deploy
5. Bind a domain (optional)

Deploy to Cloudflare

1. Fork the project to your GitHub
2. Create a Worker locally using npm run deploy -- --var "CORS_ORIGIN:dns.surf" "WORKER_HOST:dns.html.zone". Please modify the variable value: $CORS_ORIGIN to the domain name of your web page for cross-origin verification, and $WORKER_HOST to the access domain name of your Worker for source retrieval.
3. Link the Worker to GitHub in Cloudflare Dashboard and configure build script npm run deploy -- --var "CORS_ORIGIN:dns.surf" "WORKER_HOST:dns.html.zone"
4. Configure DNS resolution
   1. After copying the ENV file locally using cp .env.example .env
   2. Modify WORKER_HOST to the access domain of the Worker, CLOUDFLARE_ZONE_ID to the ID of the domain's ZONE, and CLOUDFLARE_API_TOKEN to the Cloudflare API Token, which needs permissions for 'reading user information', 'editing Workers', and 'editing DNS'
   3. Then use npm run cf-dns to configure DNS resolution.
5. Create a new Pages project on Cloudflare
6. Select the DNS.Surf project and Next.js(static) framework
7. Set environment variables and deploy
8. Bind a domain (optional)
