Overview

Cloudflare Workers is a serverless platform that runs code in Cloudflare data centers around the world. It uses V8 isolates rather than containers, which keeps cold starts very short.

Developers use Workers for APIs, full-stack web apps, request routing and middleware, and background jobs. It pairs with Cloudflare storage products such as KV, D1 (SQLite), R2 (object storage) and Durable Objects for stateful workloads.

Pros & cons

Pros

Near-instant cold starts and global distribution by default
