Nginx vs Apache: Which Web Server Should You Choose?

Nginx and Apache are the two web servers most developers meet first. Both are mature, free, open-source and capable of serving anything from a personal blog to a busy application. The real question is not which is "better" but which fits your project, your habits and your software. This article compares them on the points that matter in practice.

How they handle connections

Apache's behaviour depends on its Multi-Processing Module (MPM). The older prefork model uses one process per connection, the worker model uses threads, and the modern event MPM uses an event-driven approach for idle keep-alive connections. Nginx was designed from the start around an event-driven model in which a small number of worker processes handle many connections without creating a thread for each.

In practice, both can serve large numbers of visitors when properly configured. Nginx tends to use less memory when serving many concurrent connections, particularly static files, which is why it is common as a front-line server or reverse proxy. Apache with the event MPM narrows that gap considerably. Be wary of any article that gives exact speed multipliers: results depend heavily on configuration, hardware and workload.

Configuration and .htaccess

This is often the deciding difference for web developers:

• Apache supports per-directory overrides in .htaccess files. A user without server access can change rewrite rules, redirects and access controls just by editing a file in their site folder. Apache re-reads these on every request, which is flexible but adds overhead.
• Nginx has no .htaccess equivalent. All configuration lives in central files, and changes need a reload. That is faster and tidier, but it means rules shipped for Apache must be translated by hand.

Many PHP applications, notably WordPress plugins and frameworks, document their rewrite rules as .htaccess snippets. On Nginx you need the equivalent location rules. For WordPress, the core permalink rule is a short try_files $uri $uri/ /index.php?$args; line, but plugins that write extra .htaccess rules will not work unless you add matching Nginx configuration yourself.

Dynamic content, modules and features

Apache can run PHP inside the server with mod_php (tied to the prefork MPM), or hand requests to PHP-FPM. Nginx cannot run PHP itself and always passes requests to PHP-FPM through FastCGI. Using PHP-FPM with either server is now the common, recommended pattern because it separates the web server from the PHP processes and allows per-site pools and users.

For Node.js, Python, Ruby or Go applications, both servers act as a reverse proxy to the app. Nginx's proxy configuration is concise and widely documented, so it is the usual choice in front of application servers.

Modules and features

Apache has a large collection of modules that can be loaded dynamically, such as mod_rewrite, mod_security integrations and authentication modules. Nginx historically required modules to be compiled in, although dynamic modules are now supported and distributions package many of them. Both support HTTP/2, TLS, load balancing, caching and rate limiting. Check that any specific feature you need exists in the build your distribution ships.

Security and maintenance

Neither server is inherently more secure. Both receive security fixes through normal distribution updates, and in practice incidents come far more often from outdated applications, weak passwords and sloppy configuration than from the web server itself. What matters is that you keep the package updated, expose only what you need and read your logs. The more useful question is which server you will configure correctly, and that usually comes down to which one has documentation and examples that match your application and your experience.

It is also worth knowing that Apache's per-directory .htaccess lookups cost a little on every request, because the server checks each directory in the path for override files. On a site with a well-organised central configuration you can switch overrides off and recover that time.

A quick comparison

Topic	Apache	Nginx
Connection model	Process/thread MPMs, event MPM available	Event-driven workers
.htaccess	Supported	Not supported
Static files	Good	Very good
PHP	mod_php or PHP-FPM	PHP-FPM only
Reverse proxy	Yes (mod_proxy)	Yes, a common primary use
Shared hosting fit	Excellent, per-user overrides	Less convenient

Using both together

You do not always have to choose. A classic arrangement puts Nginx in front, serving static files and handling TLS, while Apache behind it runs applications that depend on .htaccess. Plesk supports this combination: it can run Nginx as a front end to Apache, giving you quick static delivery with full .htaccess compatibility.

How to decide

• Choose Apache if you host classic PHP sites, need .htaccess compatibility, or share a server with people who manage their own sites.
• Choose Nginx if you run your own applications, want a lean reverse proxy, or are comfortable with central configuration.
• Choose both if you want static speed with Apache compatibility, and let a control panel handle the wiring.

If you are unsure, start with whichever your application's documentation describes best. Switching later is possible, though rewrite rules and redirects need careful retesting.
