Apache, Nginx, and Caddy

by | Jan 8, 2023 | Uncategorized

Web servers are computer programmes that receive user requests sent through HTTP network protocols or its secure variant, HTTPS (used for delivering web content) and process them before returning the results to the users in the form of pertinent documents. Communication between the receiver service and the service provider (server) is made possible by protocols like HTTP (client).

You’ve probably heard of Nginx and Apache and are familiar with them to some extent, but Caddy may be unfamiliar to you. Contrary to popular belief, Caddy, a newly discovered web server, has managed to win over many fans with its adaptability and top-notch performance and has established itself as a formidable rival to Nginx and Apache.

When Apache was introduced as the first web server in 1995, users were forced to use it as such and were not concerned about selecting a web server that would meet their needs. With the development of technology and the increased diversity of current web servers, selecting a web server has grown more challenging.

Because we choose to explore the major components of the distinction between Caddy, Nginx, and Apache web servers in this post, it might be an excellent reference for selecting the appropriate web server for your needs by contrasting Caddy, Nginx, and Apache web servers.

The Apache definition

Although we have already discussed what a web server is and what it does, we did provide a brief overview of those operations at the beginning of this post. In 1995, Apache became the first and most widely used web server on the market as a result of the development and global conquest of the Internet in the 1990s. Apache was required to receive documents from a particular address upon user request and to deliver the response in the user’s browser using the DNS and IP system. Web servers are therefore crucial to the delivery of website content.

As a result, Apache, created by the Apache Foundation and maintained under the Apache licence, is the oldest and most frequently used web server. Because of its antiquity, this web server now supports more than 46% of all websites on the planet.

The Httpd server process in the market is another name for Apache, a cross-platform, free and open-source web server created in the C programming language. Most web servers can run both Windows and Linux operating systems, however Linux and Linux VPS are among the best operating systems for running web servers. Both in cPanel hosts and as a component of the LAMP stack (Linux, Apache, MySQL, and PHP), Apache is used.

Features of the Apache web server

  • It is an essential part of LAMP (Linux, Apache, MySQL, and PHP).
  • suitable for websites powered by WordPress.
  • The oldest web server is that one.
  • On Linux servers, it performs really well.
  • .htaccess files enable further settings on any directory.
  • It also supports MS Windows in addition to Unix systems.
  • It suggests using a process-driven methodology and an event-driven architecture.
  • makes a fresh thread for every request.
  • There is a sizable, ongoing support network for it. Through mailing lists, IRC, and stack overflow, it is frequently maintained by the knowledgeable team of ASF programmers and independent businesses like OpenLogic.

Apache web server drawbacks

With various configuration options, security vulnerabilities could be introduced.
On websites with high traffic, it doesn’t operate at its best, and its performance could be affected.

Presenting Nginx

To address the C10K issue, a Russian programmer named Igor Sysoev created and sold a web server called Nginx in 2004. (management of web sockets for simultaneous connection of users). In those years, web servers had trouble connecting more than 10,000 users at once and responding to requests in a timely manner. Nginx was created to address these performance issues.

Therefore, 10,000 simultaneous connections can be handled by this programme without affecting the overall set’s performance. This feature of Nginx sets it apart from its rivals and enables it to examine related requests collectively without starting a separate process.

Therefore, 10,000 simultaneous connections can be handled by this programme without affecting the overall set’s performance. This feature of Nginx sets it apart from its rivals and enables it to examine related requests collectively without starting a separate process.

Nginx was created in 2011 under a new brand name for its company, Nginx Plus, and is developed and maintained as an open-source web server under the terms of a two-clause BSD licence. Today, Nginx serves as a reverse proxy and load balancer for HTTP, TCP, and UDP servers in addition to being a web server. Also, the IMAP, POP3, and SMTP protocols are handled by this web server as proxies. As a result, the use of this programme goes beyond just delivering documents and web information.

Because of its lightweight design and low resource usage, the Nginx web server has a high speed that effectively improves performance. Nginx’s quick speed and top performance are additional benefits.

Nginx is utilised as a web server by websites like Google, Microsoft, Apple, Facebook, Twitter, Linkedin, Netflix, Dropbox, IBM, Adobe, Cisco, and others. Thanks to its features, 40% of the most popular websites and well-known companies in the world have taken notice of it.

Although the differences between Apache and Nginx can be compared from several angles and in greater detail, we won’t do so in this post. The most intriguing fact is that despite having a longer history than Apache, Nginx has eclipsed Apache as the most used web server, and its market share is growing every day. Nginx was created with the intention of resolving issues with web servers like Apache, and at first it was utilised as an addition to the Apache web server.

Web server Nginx features

  • It is small and uses fewer resources.
  • effectively manages static content.
  • It is a fully developed web server that serves as a reverse proxy, load balancer, mail proxy, and HTTP cache in addition to other effective applications.
  • Mailing lists, IRC, stack overflow, and forums are used for support.
  • It works nicely with websites that are hosted on VPS.
  • It controls over 10,000 users who connect at once.
  • It suggests using an event-driven strategy.
  • manages a thread of several requests.

Nginx’s drawbacks

  • It provides you with fewer modules and plugins than Apache does.
  • fails miserably on Windows.
  • Although it is utilised more than Apache, it has less support communities.

Define Caddy

Carl Drechsel created and developed Caddy, an open-source, multi-platform web server, in 2015 with the goal of being user-friendly, portable, effective, and offering a secure environment. GitHub also hosts this software. The Caddy web server offers by default support for HTTP/2 and HTTP, as well as HTTPS by supplying and renewing certificates (through Let’s Encrypt). Because Caddy supports HTTPS, users can access the websites that Caddy offers on a safe network.

Caddy was created using the Go programming language and standard Go libraries. It can therefore be installed on any system that Go is compiled for, including Windows, Linux, Solaris, BSD, and macOS. Caddy differs from the other two web servers we discussed in this post in that it offers functionalities right out of the box.

Despite its youth, Caddy has been able to win over a lot of fans because to its top-notch features. More than 20,000 people have downloaded and installed this web server so far, and 4,500 of them have given it stars on GitHub.

One of Caddy’s useful features is the implementation of the most recent transport security standard (TLS 1.3). Depending on your needs, Caddy can be modified and expanded. For simple control and maintenance of numerous websites on one server, Caddy includes a web-based management interface.

Caddy Webserver offers licencing in three distinct ways, as should be noted: 1. Individual 2. Small-Scale Business 3. Serious commercial

Caddy is simple to use, instal, and configure; just get the correct static binaries for your system from GitHub and set it up. Any website that begins using Caddy will automatically use HTTPS and will be given a free security certificate, similar to what Cloudflare offers.

Advantages of a caddy web server

  • Let’s Encrypt TLS certificates are automatically received and managed to enable HTTPS serving static files.
  • Give websites security certifications
  • Support for HTTP/1.1 and HTTP/2 by default
  • backward proxy support
  • simplicity in installation and use
  • high tempo
  • Balanced loads and ongoing health checks
  • FastCGI Proxy assistance
  • support for Gzip
  • host a virtual server on a port

Disadvantages of Caddy

  • There isn’t a lot of documentation on training and troubleshooting available.
  • Some functional features are not supported.
  • For big websites with lots of traffic, performance might not be optimum.
  • Its market share is modest.

Configuration of Apache vs. Nginx vs. Caddy

Configuration of the Apache web server

The primary Apache web server configuration is stored in the /etc/httpd/httpd.conf file in Red Hat Enterprise Linux and Fedora-based distributions, as well as the /etc/apache2/apache2.conf configuration file in Debian-based editions.

The required configuration of the Apache web server is as follows:

  • To specify a different configuration file, you need to use the -f flag along with other directives.
  • To setup the web server in multiple.conf files, use theIncludecommand.
  • You can edit the.htaccess file at the directory level in the server setup to modify specific websites without changing the overall settings.
  • In Debian-based distributions, you can use the a2enmodanda2dismodcommands to enable and disable a module without making any modifications to the web server’s primary configuration.

NOTE-It is advised to disable.htaccess files by setting the AllowOverride directive to none because activating this file may result in increased TTFB and CPU consumption, which reduces performance.

NOTE- Restart Apache after making the necessary modifications to the web server settings for them to take effect.

Configuration of the Nginx web server

In Linux and Unix operating systems, you can look in the /etc/nginx/ directory to discover the main Nginx configuration file with the name nginx. conf. The following configurations for Nginx are available:

  • By generating a worker process in each CPU, Nginx reduces the amount of hardware resources that are consumed.
  • The worker processes directive in Nginx has auto set as one of its default settings.
  • Instructions are organised into blocks or fields for Nginx configuration. You may see an illustration of the Nginx configuration file in the section below:

user www-data;

worker_processes auto;

pid /run/nginx.pid;

include /etc/nginx/modules-enabled/*.conf;

events {

. . .


http {

. . .


Configuration of the Caddy web server

Caddy supports JSON and several adapters in its configuration. Caddy main configurations include the following:

  • Standard Caddyfile can be used to configure Caddy.
  • Following is an illustration of a “Hello World” configuration in Caddy with a connection to port 3000.

:3000 {

respond “Hello, world!”


  • Start the web server by typing the caddy startcommand after stopping the server by pressing the Ctrl+C keys in order to restart it and apply the modifications. (Starting the Caddy server daemon by typing caddy run in the command line)
  • You can reload the caddy by running the caddy reloadcommand in a different terminal environment to apply the updated settings.
  • The phrase “Hello, world!” can be accessed. You can use the curl command or a browser search to find http://localhost:3000:

$ curl http://localhost:3000

Hello, world!

  • Implement a static file server by running the the file servercommand.
  • For proxies to send requests to PHP FastCGI, enter the php fastcgicommand.
  • Incoming traffic is routed to one or more backends using reverse proxycommand after load balancing, health checks, and automatic retries.


Is Apache more secure or Nginx?

In terms of overall security, there is no discernible difference between the two, but if we were to compare them specifically, Nginx would win out for performance and management of both static and dynamic content. The operating system support, versatility, module support, and security of Apache are superior.

Can Apache and Ngins run simultaneously on the same system

Yes, you can combine two web servers to increase performance. For instance, use Apache to handle configuration customization needs and Nginx as a backup web server and reverse proxy server to get the best performance.

It is important to note that you cannot operate two web servers concurrently without modifying the ports and IPs of the web servers from their default setup because both web servers utilise the same port and IP to listen.

Which one is faster ngins ,apache or caddy

Although Nginx handles more requests than Apache, it performs quicker than Apache because it manages thousands of incoming connections optimally per worker and has worker processes per CPU/core. To compare Nginx and Caddy, you can gain performance with a high speed of about 10–20% using Caddy if the metrics code is removed and appropriate modifications are made.


There are many different web servers available nowadays, and each one stands out from its rivals thanks to special features. In this essay, we analysed and discussed the differences and characteristics of three widely used web servers: Apache, Nginx, and Caddy.

Due to the fact that Nginx overcame the drawbacks and limitations of earlier web servers and was able to handle a large volume of simultaneous requests, Nginx has won the largest market share in this battle.

Additionally, Nginx provided users with the new Plus brand, which includes a number of extra support capabilities for media streaming, monitoring, and load balancing. But it’s important to remember that Caddy’s straightforward configuration and Let’s Encrypt’s automated HTTPS support. Additionally, Caddy offers some Nginx capabilities that are exclusive to its non-free Plus edition to users without charge and has accelerated its development to keep up with rival web servers.

Caddy web servers are appropriate for tiny sites and concentrate on performance and usability, whereas Apache and Nginx web servers are good for handling high traffic volumes and supplying vast amounts of static material. If adaptability and customisation are important to you, Apache can satisfy your needs.

Considering your requirements and expectations can help you choose the best web server among these three well-known options. In addition, one of the notable benefits of Caddy is the simplicity of configuration and use, therefore if you’re seeking for ease of use, you should choose the Caddy web server. Nginx is the best web server for managing high traffic.

We hope that the comparison of the Apache, Nginx, and Caddy web servers will help you select the one that best meets your requirements.
