Overview

Fresh is a modern, full-stack web framework built on Deno and Web Standards, designed for building high-quality, performant web applications. It uses island architecture—rendering pages as server-generated HTML by default and shipping JavaScript only for interactive components. This approach delivers fast page loads and zero configuration needed for TypeScript support.

The framework emphasizes simplicity and productivity with no config files, no build step, and no node_modules. It includes built-in features like file-based routing, WebSockets, View Transitions, OpenTelemetry support, and progressive form handling. Fresh is ideal for server-rendered sites like e-commerce shops, documentation, landing pages, and CRUD applications.
