Hyperdrive

Hyperdrive solves the specific, painful problem of talking to a traditional Postgres or MySQL database from a serverless edge platform: connection pooling close to your database plus optional query caching, so every Worker invocation isn’t paying connection-setup tax across an ocean.

Setup is minutes — point it at your connection string, swap the binding in — and the latency improvement for read-heavy workloads is dramatic and immediate. It became free with paid Workers plans, which removed the last reason to hesitate.

Points off only for opacity: you get limited visibility into pool behavior, cache hit rates, and where your pool is actually placed, and the config surface is minimal when you want to tune. But as the bridge between “we have a real database” and “we want to build on Workers,” it’s exactly the product it should be.
