Apache HTTP Server (httpd) is an open-source web server for Linux, Unix, Windows and other systems. Organisations use it to serve websites and applications, as a reverse proxy and for TLS termination. The project site lists support for HTTP/2, load balancing and a large number of modules that add functions. You install the software yourself on your own servers or in containers.
The Apache HTTP Server Project is part of the Apache Software Foundation, a US not-for-profit organisation incorporated as a corporation under Delaware law. The software is released under the Apache License 2.0, an OSI-approved licence, and the source code is public. Because you run httpd yourself, traffic and log data stay on your own infrastructure; the foundation offers no hosted service that receives your data. The project publishes new versions regularly; the latest release shown on the project site is dated 1 October 2026.
