What are Web Servers?
Web servers, also known as HTTP servers, are servers that host websites and web applications. Web servers are the backbone of all sites and web apps on the internet. Many popular web servers are open source. Different web servers have advantages and disadvantages when compared to one another, and selecting the right one depends on use case, deployment, operating system, and more. Compare and read user reviews of the best Web Servers currently available using the table below. This list is updated regularly.

KSWEB
KSLabs
It is enough to install KSWEB on your Android device and copy scripts to the htdocs folder on the memory card. After that, you can run your web content! So, KSWEB is a set for web developers for the Android platform. The package consists of a web server, FTP server, PHP programming language, MySQL DBMS and scheduler. KSWEB does not need root rights for proper functioning, unless, of course, you want to use the server on port 80. By the way, it can be convenient when opening your server on the Internet. This will allow you to have a small hosting in your pocket! To start the web server, you need to start KSWEB, specify, if necessary, the port and the root directory. By default, KSWEB contains fully-configured configuration files for all components. Our package easily runs popular CMS and frameworks such as Yii2, Drupal, Joomla, WordPress, MODX, etc. If you have any questions about how to run this or that CMS we will answer them!Starting Price: $4.99 one-time payment -

Node.js
Node.js
As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep. This is in contrast to today's more common concurrency model, in which OS threads are employed. Thread-based networking is relatively inefficient and very difficult to use. Furthermore, users of Node.js are free from worries of dead-locking the process, since there are no locks. Almost no function in Node.js directly performs I/O, so the process never blocks except when the I/O is performed using synchronous methods of Node.js standard library. Because nothing blocks, scalable systems are very reasonable to develop in Node.js. Node.js is similar in design to, and influenced by, systems like Ruby's Event Machine and Python's Twisted. Node.js takes the event model a bit further. It presents an event loop as a runtime construct instead of as a library. -

Tornado Web Server
Tornado
Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. Tornado is different from most Python web frameworks. It is not based on WSGI, and it is typically run with only one thread per process. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written to use Tornado’s own interfaces (such as tornado.web) directly instead of using WSGI. In general, Tornado code is not thread-safe. Tornado is integrated with the standard library asyncio module and shares the same event loop (by default since Tornado 5.0). In general, libraries designed for use with asyncio can be mixed freely with Tornado. -

OpenResty
OpenResty
OpenResty® is a full-fledged web platform that integrates our enhanced version of the Nginx core, our enhanced version of LuaJIT, many carefully written Lua libraries, lots of high-quality 3rd-party Nginx modules, and most of their external dependencies. It is designed to help developers easily build scalable web applications, web services, and dynamic web gateways. By taking advantage of various well-designed Nginx modules (most of which are developed by the OpenResty team themselves), OpenResty® effectively turns the nginx server into a powerful web app server, in which the web developers can use the Lua programming language to script various existing nginx C modules and Lua modules and construct extremely high-performance web applications that are capable to handle 10K ~ 1000K+ connections in a single box. OpenResty® aims to run your server-side web app completely in the Nginx server, leveraging Nginx's event model to do non-blocking I/O with the HTTP clients. -

quark
suckless.org
The goal of this project is to do one thing and do it well, namely serving static web directories and doing that right. Most other solutions either are too complex (CGI support, dependencies on external libraries, etc.) or lack features you expect (TLS, virtual hosts, partial content, not modified since, etc.). quark tries to find a midway and just restrict itself to being static while still offering functions you only find in more bloated solutions and being as secure as possible (chroot, privilege dropping, strict parsers, no malloc at runtime, pledge, unveil, etc.). We believe that most of the web does not need to be dynamic and increasing complexity on server-side applications is one of the main reasons for the web obesity crisis. The common approach nowadays is to do everything on the server, including parsing requests, modifying files and databases, generating HTML and all that using unfit languages like PHP or JavaScript, which is a security and efficiency nightmare. -
10
H2O
H2O
H2O is a new generation HTTP server that provides a quicker response to users with less CPU utilization when compared to older generation of web servers. Designed from the ground up, the server takes full advantage of HTTP/2 features including prioritized content serving and server push, promising an outstanding experience to the visitors of your website. Full support for dependency and weight-based prioritization with server-side tweaks. Thanks to others, H2O is provided as a binary package on some environments. Therefore you may try to at first install the software using your favorite packaging system, and then resort to installing from source. Generally speaking, we believe that using LibreSSL is a better choice for running H2O, since LibreSSL not only is considered to be more secure than OpenSSL but also provides support for new ciphersuites. -

Eclipse Jetty
Eclipse Foundation

Full-featured and standards-based. Open source and commercially usable, flexible and extensible, small footprint, embeddable, asynchronous, enterprise scalable, and dual-licensed under Apache and Eclipse. Large clusters, such as Facebook Presto. Cloud computing, such as Google AppEngine. With the direction of Java and the JakartaEE project (formerly JavaEE) in 2020, the current recommended version of Jetty for use depends upon the servlet API version, desired licensing, etc. -
