NGINX is software for serving HTTP traffic and routing requests as a reverse proxy, content cache, load balancer, TCP/UDP proxy, or mail proxy.
What NGINX is
NGINX is software for serving HTTP traffic and routing requests as a reverse proxy, content cache, load balancer, TCP/UDP proxy, or mail proxy. It supports TLS SNI, HTTP/2, and HTTP/3, along with WebSockets, response caching, rate limiting, and TLS termination. Reverse proxying can use caching, load balancing, and fault tolerance; caching and load balancing are also supported for FastCGI, uwsgi, SCGI, and memcached servers. Its feature set includes the njs scripting language. NGINX uses a master process and worker processes that run under an unprivileged user. Configuration is file-based, and the software is self-hosted for Linux, macOS, and Windows. Downloads include mainline, stable, and legacy versions, source code, Windows builds, and Linux packages. NGINX is distributed under the 2-clause BSD License. Its open-source plan is free at no cost. F5 is its primary maintainer, sponsor, and steward, and offers commercial support and enterprise distributions, including NGINX Plus.
