Nginx serves web content, acts as a reverse proxy, load balancer, and HTTP cache. Powers a significant portion of the internet.
Nginx handles more web traffic than any other server. Its event-driven architecture efficiently serves static content and proxies requests to application servers with minimal resource consumption. Most modern web deployments use Nginx as a reverse proxy in front of application servers like Node.js, Python, or Ruby, handling TLS termination, load balancing, and caching. The configuration syntax is straightforward, and the documentation covers virtually every use case. While alternatives like Caddy offer automatic HTTPS and simpler configuration, Nginx's performance characteristics and battle-tested reliability keep it as the default choice for production deployments.
