Cloudflare Workers VPC

Securely connect your private cloud to Cloudflare to build cross-cloud apps.

Available on Free and Paid plans

Workers VPC allows you to connect your Workers to your private APIs and services in external clouds (AWS, Azure, GCP, on-premise, etc.) that are not accessible from the public Internet.

With Workers VPC, you can configure a Cloudflare Tunnel to establish secure, private connections from your private networks to Cloudflare. Then, you can configure a VPC Service for each service in the external private network you need to connect to, and use VPC Service bindings to connect from Workers.

Note

Workers VPC is currently in beta. Features and APIs may change before general availability. While in beta, Workers VPC is available for free to all Workers plans.

index.ts

TypeScript

export default {
  async fetch(request, env, ctx) {
    // Access your private API through the service binding
    const response = await env.PRIVATE_API.fetch(
      "http://internal-api.company.local/data",
    );

      // Process the response from your private network
      const data = await response.json();

      return new Response(JSON.stringify(data), {
        headers: { "content-type": "application/json" },
      });
    },
