What each one is

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

Deno Fresh

Fresh is a web framework that renders pages on the server by default, serving plain HTML with zero JavaScript to browsers unless you explicitly enable interactive components. It eliminates configuration files, build steps, and node_modules, using Preact-powered islands for selective client-side interactivity.
