The framework distinguishes itself by utilizing adapter-based integration to link various backend environ

Hotwire Turbo is a server-driven navigation and HTML streaming framework that intercepts link clicks and form submissions to fetch pages in the background and replace content without full browser reloads. It provides a Turbo Frame component that scopes page regions into independent contexts, enabling partial page updates where only a specific area of the page navigates or loads content. The framework includes a page cache and morph system that stores recently visited pages for instant restoration and applies minimal DOM changes on refresh, preserving scroll position and element state. The fra

GCDWebServer is a lightweight HTTP 1.1 server for iOS, macOS, and tvOS.
