Cloudflare Workers

Cloudflare's edge compute platform, running JavaScript, TypeScript, Python and Rust in V8 isolates on the network that already serves the request.

Code next to the visitor.

Cloudflare Workers runs code in V8 isolates on Cloudflare’s network, close to the visitor and without the cold-start cost of a container. Cloudflare documents first-class support for JavaScript, TypeScript, Python and Rust, and describes WebAssembly as the route for everything else, naming C, C++, Kotlin and Go as examples.

Two plans exist. The free one comes with every account by default and includes a daily request allowance with a short CPU-time budget per invocation. The paid one carries a monthly minimum and meters requests and CPU time above the included amounts. Storage, queues and databases are separate Cloudflare products a Worker calls into.

Worth knowing

The execution model is the constraint that decides whether an application fits. A Worker is scoped to a single request, with a CPU-time budget per invocation and no persistent local filesystem, so a long-lived process, local file writes and a conventional database connection pool have no place to live. The shape the platform is built for is edge logic: request rewriting, authentication checks, personalisation ahead of the cache.
