Apache Web Server, launched in 1995, is an open-source, cross-platform web server widely used for hosting HTTP-based websites, though its popularity has declined due to the rise of competitors like Nginx. Developed by an open community under the Apache Software Foundation, Apache supports numerous programming languages, authentication mechanisms, database support, and server-side scripting across various operating systems. For local hosting, tools like XAMPP, LAMP, and WAMP simplify the deployment process, while Apache can also be installed directly from Apache Lounge. Additionally, LambdaTest offers cloud-based testing for locally hosted websites, enabling real-time cross-browser testing through a tunnel feature, which helps developers ensure cross-browser compatibility before launching their sites.
