What each one is

The product in its own terms, so the numbers below have context.

Independently observed

Cloudflare Workers

Leader

A serverless platform enabling developers to deploy applications and scripts that run across Cloudflare's global infrastructure, scaling automatically from zero requests to millions, with billing based on actual execution time rather than reserved capacity.
