Overview · Cloudflare Hyperdrive docs

Turn your existing regional database into a globally distributed database.

Available on Free and Paid plans

Hyperdrive is a service that accelerates queries you make to existing databases, making it faster to access your data from across the globe from Cloudflare Workers, irrespective of your users' location.

Hyperdrive supports any Postgres or MySQL database, including those hosted on AWS, Google Cloud, Azure, Neon and PlanetScale. Hyperdrive also supports Postgres-compatible databases like CockroachDB and Timescale. You do not need to write new code or replace your favorite tools: Hyperdrive works with your existing code and tools you use.

Use Hyperdrive's connection string from your Cloudflare Workers application with your existing Postgres drivers and object-relational mapping (ORM) libraries:

import { Client } from "pg";
export default {
  async fetch(request, env, ctx): Promise<Response> {
    // Create a new client instance for each request. Hyperdrive maintains the
    // underlying database connection pool, so creating a new client is fast.
    const client = new Client({
      connectionString: env.HYPERDRIVE.connectionString,
    });
    try {
      // Connect to the database
      await client.connect();
      // Sample SQL query
      const result = await client.query("SELECT * FROM pg_tables");
      return Response.json(result.rows);
    } catch (e) {
      return Response.json({ error: e instanceof Error ? e.message : e }, { status: 500 });
    }
  },
} satisfies ExportedHandler<{ HYPERDRIVE: Hyperdrive }>;
