The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.

The Apache HTTP Server ("httpd") was launched in 1995 and it has been the most popular web server on the Internet since April 1996. It has celebrated its 25th birthday as a project in February 2020.

The Apache HTTP Server is a project of The Apache Software Foundation.

The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.4.53 of the Apache HTTP Server ("httpd").

This latest release from the 2.4.x stable branch represents the best available version of Apache HTTP Server.

Apache HTTP Server version 2.4.43 or newer is required in order to operate a TLS 1.3 web server with OpenSSL 1.1.1.

MapServer is an open-source development environment for building spatially enabled internet applications, built in the C language, and is widely known as one of the fastest Web mapping engines available. It can run as a CGI program or via MapScript which supports several programming languages (using SWIG). MapServer can access hundreds of data formats, any raster or vector format supported by GDAL, and reprojections on-the-fly are handled by PROJ. MapServer was originally developed by Steve Lime, then working at the University of Minnesota — so, it was previously referred to as "UMN MapServer", to distinguish it from commercial "map servers"; today it is commonly referred to as just "MapServer", and is maintained by the MapServer Project Steering Committee (PSC). MapServer was originally developed with support from NASA, which needed a way to make its satellite imagery available to the public

Mapbender is a graduated project of the Open Source Geospatial Foundation. It was awarded OGC web site of the month in 2008 It is used by PortalU and several federal states to implement the INSPIRE regulation Many municipalities use Mapbender as City Map Services  and it is used as the mapping framework for online cycle route planners

Mapbender is a web mapping software implemented in PHP and JavaScript, the configuration resides in a data model stored in a PostgreSQL PostGIS or MySQL database. It is developed as an open-source project and licensed by the GNU GPL as free software. Mapbender is a framework for managing spatial data services that are standardized following the OGC specifications OWSWMS and WFS and using the formats GeoRSS and GML and Web Map Context. The framework implements user management, authentication and authorization. Management interfaces for user, group and service administration are stored as configurations in the database.

MapGuide Open Source is a web-based map-making platform that enables users to quickly develop and deploy web mapping applications and geospatial web services. The application was introduced as open-source by Autodesk in November 2005, and the code was contributed to the Open Source Geospatial Foundation in March 2006 under the GNU LGPL.

MapGuide features an interactive viewer that includes support for feature selection, property inspection, map tips, and operations such as buffer, select within, and measure. MapGuide includes an XML database for storing and managing content, and supports most common geospatial file formats, databases, and standards. The MapGuide platform can be deployed on Linux or Microsoft Windows, supports Apache and IIS web servers, and offers extensive PHP.NETJava, and JavaScript APIs for application development.
