Cloudflare Workers is a serverless platform that runs your code on Cloudflare’s global edge network, close to users, rather than in a single regional data centre. Each request is handled by a lightweight V8 isolate that starts in well under a millisecond, so there are no cold starts and no servers to manage.
Workers suits APIs, full web applications, and AI features that need low latency everywhere and predictable cost. It pairs with the rest of the Cloudflare platform — D1 for SQL, R2 for object storage, Vectorize for embeddings, Durable Objects for state — so an entire product can run on one runtime instead of stitching services together.
This site is itself a Cloudflare Worker. We build on Workers end to end rather than treating it as a cache in front of an application hosted elsewhere.
