What each one is

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

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.

Independently observed

OpenFaaS

Open-source serverless framework that abstracts cloud provider differences, allowing you to deploy and run functions across multiple clouds, on-premises, and Kubernetes with extended execution timeouts and support for many programming languages.
