Web Development Trends 2021


According to the eCommerce Foundation, 88% of buyers look online for information before they make purchases. These statistics emphasize the importance of a website for today’s businesses.

A website is a collection of publicly accessible, interlinked pages that share a single domain name.

By having an online presence through your website, you are able to reach more users. The more buyers you reach online, the more opportunities you get to make a sale. But developing a website doesn’t mean that you bring a new audience to the company automatically. Each year, new trends and technologies shape the environment that web developers find themselves in. One year is marked by chatbots, another by advanced design, and another by new frameworks, etc.

Keeping up with all of those changes is enough to confuse most businesses. But that’s why you’re here. Because you refuse to be confused and you know the significance of being ready for the future. Since over half of entrepreneurs are going to upgrade their websites, it’s not unlikely the case with your own business. To keep up, you need to be familiar with the web development trends that will shape 2021.

First, let’s overview the current situation on the market, then discuss future trends.

Current Technology Trends in Web Development

We have studied the last years’ tendencies to create this list of the most critical web development trends.

current trends in web development

Content personalization

This tendency has been staying with us for the last several years. The fundamental goal of content personalization is to deliver publications, messages, and offers based on users’ behavior, location, or interests. In principle, the software analyzes incoming information, defines patterns, makes solutions, and improves its work.

I.e. Airbnb uses machine learning to personalize search results for travelers to boost the probability of host acceptance of their request.

Data security

One more noticeable trend in the last years is data security. The more data a web app saves, the more interesting it looks to cybercriminals. They aim to spoil your services and steal your customers’ data or internal business information. This can cause huge harm to your reputation and cost you a lot.


One more popular trend is chatbots. A chatbot is a computer program that simulates human conversation through text or voice chats or both. Bots aggregate information from customers through a series of questions. They interpret and identify what the user said, infer what they mean and/or want, and determine a series of appropriate responses based on this data.

Internet of Thing (IoT)

Internet of Things has been phenomenal during the last few years. IoT is quite similar to products pertaining to the concept of the “smart home”, including devices and appliances. According to statistics, the IoT market is set to cross $1.6 trillion by 2022. The market is driven by growth in the development of web tools for echo dot, home security systems, and other smart devices. Companies can leverage outstanding IoT-based smart technology.

RAIL Model

Like the other trends, RAIL didn’t appear in 2020. The concept turned out in 2015, but it became popular only in 2019. Let’s take a look at what abbreviation means.

  • Responsive. Each input will get a response in 50 milliseconds.
  • Animation. This point includes entrance and exit animations, scrolling, dragging, and loading indicators.
  • Idle. It refers to what is happening behind the scenes of your site after it has initially loaded. Idle time gives a perfect opportunity for preloading, prefetching, and preconnecting resources.
  • Load. It supposes loading the main blocks of the page in less than one second. The faster the page loads, the less probability that users get bored and go to the other website.

RAIL model is aimed to create a better user experience. When customers don’t have to wait for minutes while all website content will be loaded. According to statistics, 39% of customers will stop engaging with a website if images won’t load or take too much time to load.

Single-page Apps (SPA)

A single-page application is an app that works inside a browser and does not need to reload the page during use. It shows better page performance and gives a high degree of security.

Why did single-page apps become so popular? JavaScript frameworks are actively rising. And SPA uses this language for content loading. These apps don’t need any extra waiting time. So, they provide immediate feedback.

We briefly overviewed last years’ trends. But what does the future prepare for us in 2021? Read on to get more information.

Future Trends in Web Development

Progressive Web Applications (PWA)

PWAs aren’t the novelty of 2021. Nevertheless, technology began to gain popularity in 2019 through developers and investors due to performing an excellent user experience.

One more peculiarity of PWA is an opportunity to send push notifications without downloading additional apps. It is worth mentioning that push notifications are still one of the hottest trends.

Mobile-First Approach

Flexibility was a trend for a long time. Now it’s not a tendency, but a necessity. In 2021 the mobile will come to the fore. It means that Accelerated Mobile Pages (AMP) will be on the top of popularity. AMP suits all web applications, users of which prefer to use smartphones to browse the websites.


The key thing in web development is performance. Unfortunately, JavaScript makes heavy mathematical calculations slow. It influences user experience in a bad way. Because of that fact, WebAssembly appeared. WebAssembly is a small, fast binary format that promises near-native performance for web applications.

What makes WebAssembly so popular? It’s independent of programming language, platform, and hardware. The main advantage of WebAssembly is the possibility to execute code fast and ensure a high level of security.

Motion design UI

According to statistics, 94% of first impressions related to your site’s web design. The essential 2021 web design tendency is Motion design UI. The laconic design combined with attractive interactions compels people’s attention. If you want your website to look advanced, you should add charts, pop-ups, pull-down menus, dragging, page-header transitions, etc.

All these elements display a unique company concept and attract users.

Voice Search and Navigation

Most devices, that are around us, are able to hear our voices. Smartphones, smartwatches, laptops, tablets, even some automobiles can be managed by voice. After a while, it becomes a habit. Thus, people subconsciously expect that all devices contribute to this opportunity. Web development has to react to it. It means that you should work on voice search and website navigation. It gives customers convenience, a high speed of task accomplishment, and a user-friendly experience.


Listed before trends don’t require certain technologies. But what tech stack will be used the most often? First of all, it’s MEAN technology. MEAN includes:

  • MongoDB – a NoSQL database program;
  • Express.js – modular web application framework package for Node.js;
  • Angular – a TypeScript-based open-source web application framework;
  • Node.js – an open-source, cross-platform, back-end framework.

Moreover, React, Vue, and Flutter are supposed to be widespread as well. React is a library that used to replace Angular in MEAN-stack. It allows for making changes faster. Thus, more and more developers prefer to use it.

Vue is a framework that became popular fast because such global companies as Xiaomi and Alibaba had chosen it for development. This is a sensible front-end choice.

One more widespread technology is Flutter for Web. It gives the opportunity to ensure the excellent work of web applications on any device.

The Bottom Line

It can be difficult to follow tendencies since they change so fast. Nevertheless, most of the future trends didn’t appear today. So why not implement them on your website?

Notice that despite the dynamic approaches, tech stacks, and attitudes, the fundamental goal of website development is to ensure an excellent user experience. This is the one trend that will stay with us forever.
