Nginx vs Apache HTTP Server
Compare Nginx and Apache HTTP Server on architecture, performance, configuration style, .htaccess, modules, and typical deployment roles in modern stacks.
Quick Answer
Nginx's event-driven architecture serves high-concurrency traffic and static files with less memory, which is why it fronts most modern deployments as a reverse proxy. Apache remains beloved for its flexibility: per-directory .htaccess overrides, a vast module ecosystem, and decades of documentation. New builds usually start with Nginx; shared hosting and legacy PHP stacks keep Apache everywhere.

| Feature | Nginx | Apache HTTP Server |
|---|---|---|
| Architecture | Event-driven, asynchronous workers | Process/thread MPMs (prefork, worker, event) |
| Configuration Model | Central declarative config | Central config + per-directory .htaccess |
| .htaccess Support | ||
| Dynamic Content | Via upstream (PHP-FPM, proxied apps) | In-process (mod_php) or proxied |
| Reverse Proxy | Built-in, industry standard | mod_proxy |
| Module Ecosystem | Compiled-in / dynamic modules | Very large ecosystem, runtime-loadable |
| Memory Under Load | Low and flat | Higher, per-connection |
| License | BSD-style (core) | Apache License 2.0 |
Nginx
An event-driven web server, reverse proxy, and load balancer designed for high concurrency with a small, predictable memory footprint.
Pros
- Handles tens of thousands of concurrent connections efficiently
- Excellent static file performance and sendfile support
- First-class reverse proxy, load balancing, and caching
- Low, predictable memory usage under load
- De-facto standard in container and Kubernetes ingress setups
- Simple TLS termination with modern protocol support
Cons
- No .htaccess equivalent — all config is central
- Dynamic content always needs an upstream (PHP-FPM, app server)
- Config reload required for most changes
- Core is open source, but some features live in paid NGINX Plus
Best For
Reverse proxying app servers, serving static assets and SPAs, TLS termination, load balancing, and any high-concurrency front door.
Apache HTTP Server
The Apache Software Foundation's veteran web server — process/thread-based with the event MPM available, famous for per-directory configuration and an enormous module ecosystem.
Pros
- .htaccess allows per-directory overrides without touching main config
- Massive module ecosystem (mod_rewrite, mod_security, mod_php…)
- Decades of documentation, tutorials, and Stack Overflow answers
- Event MPM narrows the concurrency gap considerably
- Ubiquitous on shared hosting and classic LAMP stacks
- Fully open source under the Apache License
Cons
- Higher memory use per connection than Nginx under heavy load
- .htaccess lookups cost performance when enabled
- Config syntax is verbose compared to modern alternatives
- Less common as the front proxy in new cloud-native designs
Best For
Shared hosting, legacy LAMP applications, environments where users need per-directory control, and stacks built around Apache-specific modules.
Architecture: Events vs Processes
Nginx was created specifically to solve the C10K problem: a handful of worker processes each run an event loop that multiplexes thousands of connections, so memory stays flat as traffic spikes. Apache historically dedicated a process or thread per connection (prefork/worker MPMs); its event MPM now handles keep-alive connections asynchronously and narrows the gap substantially. The remaining practical difference: Nginx's model is the same in every install, while Apache's behavior depends on which MPM and modules a given host enabled — mod_php, for example, forces the memory-hungry prefork model.
The .htaccess Trade-off
Apache's killer feature for shared environments is .htaccess: any directory owner can add rewrites, auth, or headers without touching — or even having access to — the main configuration. That's exactly why WordPress hosting standardized on it. The cost is real: Apache must check for .htaccess files on the path of every request, and rules scattered across a filesystem are hard to audit. Nginx deliberately refuses per-directory config; everything lives in one reviewable, testable place (nginx -t), which fits infrastructure-as-code workflows far better but rules out delegated configuration.
Where Each Actually Runs Today
In modern architectures the 'web server' role has split. The front door — TLS termination, load balancing, static assets, caching, rate limiting — is overwhelmingly Nginx (or a cloud load balancer imitating it), including as the basis of the most widely deployed Kubernetes ingress controllers. Apache remains enormous in absolute numbers via shared hosting, cPanel-style platforms, and long-lived LAMP applications, where mod_php in-process execution and .htaccess portability still matter. Neither is going anywhere; they've settled into different layers of the stack.
Performance Numbers in Context
Benchmarks consistently show Nginx serving static files faster and sustaining more concurrent connections per gigabyte of RAM, while well-tuned Apache with the event MPM is competitive for dynamic workloads — where the application, not the web server, is almost always the bottleneck. Before choosing on benchmark grounds, profile your actual stack: for a typical PHP or Python app, database queries and application code dwarf web-server overhead, and either server will saturate your app tier long before it becomes the limit.
Verdict
Default to Nginx for new deployments: it's the better reverse proxy, handles concurrency with less memory, and matches how modern stacks are assembled. Pick Apache when you need .htaccess-style delegated configuration, depend on an Apache-only module, or are operating classic LAMP/shared-hosting environments. Running Nginx in front of Apache remains a legitimate pattern that captures both strengths.
