Nginx (pronounced "engine-x") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server). The nginx project started with a strong focus on high concurrency, high performance and low memory usage. It is licensed under the 2-clause BSD-like license and it runs on Linux, BSD variants, Mac OS X, Solaris, AIX, HP-UX, as well as on other *nix flavors.[7] It also has a proof of concept port for Microsoft Windows.[8]

Nginx can be deployed to serve dynamic HTTP content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger module, and it can serve as a software load balancer.[9] Its development started in 2002 by Igor Sysoev.[10] In July 2011, a company was formed as Nginx, Inc. Its principal place of business is San Francisco, California.[11] The company offered commercial support in February 2012,[12][13] and paid NGINX Plus subscription in August 2013.[14] An investment of $10 million led by New Enterprise Associates was reported in October 2013.[15] Other investors reportedly included Aaron Levie.[16] WordPress developer Automattic and Content Delivery Network provider MaxCDN have become funding partners for an update to Google's SPDY version 3.1, slated for early 2014.[17]

Nginx uses an asynchronous event-driven approach to handling requests, instead of the Apache HTTP Server model that defaults to a threaded or process-oriented approach, where the Event MPM is required for asynchronous processing. Nginx's modular event-driven architecture[18] can provide more predictable performance under high loads.[19]

Originally, nginx was developed to fill the needs of websites including Rambler, for which it was serving 500 million requests per day by September 2008.[20] According to Netcraft's August 2014 Web Server Survey,[21] nginx was found to be the second most widely used web server across all "active" sites (14.47% of surveyed sites) and for the top million busiest sites (19.60% of surveyed sites). According to W3Techs, it was used by 24.6% of the top 1 million websites, 32.9% of the top 100,000 websites, and by 41.1% of the top 1,000 websites.[22] According to BuiltWith, it is used on 23.8% of the top 10,000 websites, and its growth within the top 10k, 100k and 1 million segments increased.[23] WorldHeritage uses nginx as its SSL termination proxy.[24] As of OpenBSD release 5.2 (1 November 2012), nginx became part of the OpenBSD base system, providing an alternative to the system's fork of Apache 1.3, which it was intended to replace.[25] Eventually, Apache was removed from the base system.[26]
