The Apache HTTP Server is a free and open-source cross-platform web server, released under the terms of Apache License 2.0. It is developed and maintained by a community of developers under the auspices of the Apache Software Foundation.

The vast majority of Apache HTTP Server instances run on a Linux distribution,[5] but current versions also run on Microsoft Windows,[6] OpenVMS,[7] and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems,[8] including ports to mainframes.[9]

Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled.[10] Apache played a key role in the initial growth of the World Wide Web,[11] quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites.[12]

As of March 2025, Netcraft estimated that Apache served 17.83% of the million busiest websites, with the other top four being Cloudflare at 22.99%, Nginx at 20.11%, and Microsoft Internet Information Services at 4.16%.[13] According to W3Techs' review of all web sites, in April 2025 Apache was ranked second at 26.4% and Nginx first at 33.8%, with Cloudflare Server third at 23.5%.[14]
