| description.long | 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. | A Ruby-based framework bundling everything needed for web development: database management, templating engines, email delivery, real-time updates, async job handling, file storage, and built-in protections against common attacks like SQL injection and cross-site scripting. |
