Microsoft WebMatrix is a free, cloud-connected website builder and HTML editor for Windows, geared towards web development. WebMatrix enables developers to build websites using built-in templates or popular open-source applications, with full support for ASP.NET, PHP, Node.js and HTML5. Microsoft developed WebMatrix for the purpose of providing web developers with coding, customization, and publishing capabilities all in one place.
WebMatrix is a successor of ASP.NET Web Matrix, which was released in 2003 and later discontinued.
In 2011, WebMatrix was released to support the large number of open source content management systems and to provide a lightweight web development environment for PHP and the new, simplified ASP.NET web pages. It focused on a clean, simple user interface allowing web developers to build websites from scratch or by customizing open-source web content management systems such as Orchard, DotNetNuke, Umbraco, Joomla!, Drupal and WordPress.
From 2011 to 2012, WebMatrix 2 Beta and RC releases added support for Node.js, mobile simulators, additional website templates, and support publishing to Microsoft Azure web sites. On September 6, 2012, the official release of WebMatrix 2 went public. The release of WebMatrix 3 was made available on May 1, 2013. Unlike WebMatrix 2, WebMatrix 3 requires Windows 7 or later.
