Progressive Web Applications (PWA)

PWA Development is the Future

In a mobile-first world, it’s natural that most companies strive to find the best mobile solutions to engage with their customers and boost their operations. In that context, the rise of Progressive Web Apps (PWA) isn’t a surprise. These apps behave like native mobile apps though they don’t have to be downloaded or installed to work. PWAs are so good and offer so many benefits that have quickly become a preferred choice for organizations across industries. We should know – BairesDev has worked in PWAs for numerous clients and has helped them revamp their businesses with their power.

We develop PWAs with a mobile app look and feel

BairesDev works with the Top 1% of Mobile Developers to provide you with the best PWA Development Services. The result? Progressive web apps that look and feel like native mobile applications but that work as if they were websites. Thus, we can build high-performing, cross-platform, and cost-effective mobile solutions through one of the most appealing modern standards of mobile development.

We develop PWAs with a mobile app look and feel

If you’re thinking about developing a mobile application, you might be having a hard time deciding whether you should go for a traditional native app or choose a Progressive Web App. The final decision will depend on several factors, including your business needs, your audience, your industry, your budget, and your available resources.

Naturally, both native apps and PWAs have their own pros and cons that will definitely influence your decision. For instance, native apps might not be indexed by Google, be more costly to develop, require installation, and be platform-specific but they can also show a superb performance and can leverage all of the device’s functionality (including Bluetooth and NFC).

PWAs, on the other hand, might relieve your customers from installation or from having to be constantly connected to use them, but they are more limited in what they can offer, functionality-wise. That’s why you need to evaluate which is better for you on a case-by-case basis. Following the suggestion below can aid you with the decision:

Develop a PWA if:

  • 1_soak_BDev_SRP_Numeros
    You are just starting your business or exploring the mobile world in your industry
  • 1_soak_BDev_SRP_Numeros
    You have time and budget constraints
  • 1_soak_BDev_SRP_Numeros
    You are looking for an impact on your SEO strategy

Develop a native app if:

  • 1_soak_BDev_SRP_Numeros
    You’re looking for a more robust and sophisticated offer with more features
  • 1_soak_BDev_SRP_Numeros
    Your mobile idea needs specific mobile device features (such as geofencing).

User experience centered

Native apps can be more sophisticated and complex than PWAs, which can certainly result in a richer user experience. But that doesn’t mean that Progressive Web Apps are lacking when it comes to UX. In fact, BairesDev’s mobile engineers work with our UX experts to come up with immersive and engaging experiences for all the PWAs we develop. We do so by focusing on the PWA’s inherent strengths, which leads us to:

  • 1_soak_BDev_SRP_Numeros
    Optimize loading times
  • 1_soak_BDev_SRP_Numeros
    Increase performance
  • 1_soak_BDev_SRP_Numeros
    Prioritize speed
  • 1_soak_BDev_SRP_Numeros
    Shine at touch implementation
  • 1_soak_BDev_SRP_Numeros
    Power the offline experience with more features

All in all, our PWA development services aim to build user-centric experiences through a “less is more” approach that guarantees increased engagement.

We take care of Service Workers

One of the biggest advances in mobile programming in recent years has been the implementation of service workers. A service worker is a specific type of web worker that consists of a JavaScript file that runs separately from the main browser. From there, it intercepts network requests, handles the cache and the resources stored there, and delivers push messages. 

Basically, service workers are key to the offline capabilities of PWAs, which is why the team developing your PWAs has to thoroughly understand them for your app to truly shine. Fortunately, you can rely on BairesDev for that. Our engineers know their way around service workers and have a special knack for leveraging their power without compromising your app’s security. That means you can trust us to build a rich mobile app that will work in all contexts.

Installability is key

One of the defining features of mobile apps is that you have to install them on your device before using them. That means that you only get to try them after you’ve downloaded and deployed them in your system which, in turn, implies you need both an internet connection and enough storage space. Depending on the user, that can be a problem, which is why PWAs are becoming so popular right now, especially because you don’t need to install them to use them.

As such, installability becomes a key factor in the mobile experience and can be decisive for your audience. The BairesDev team is very aware of this, which is why we assess you in this matter to define whether a PWA or a native app is your best choice.

Speed is important for Lighthouse and Google

Speed is without a doubt one of the biggest factors in the quality of the mobile experience. An app with low speed frustrates users and feels like a low-quality product, both of which are serious threats to any digital solution. But, aside from that, speed is also an influential item for online search visibility.

For quite some time now, page speed is one of the elements that Google’s algorithm takes into consideration to decide where to rank a specific page. And since PWAs rank in search results, ensuring the best speed for them is a must, especially for ranking higher in Google results. Doing that can be tricky but our engineers know how to do so, especially with the help of Lighthouse.

What is Lighthouse?

Lighthouse is an automated tool created by Google to help web development teams optimize the quality of their web pages. By using this audit and review tool, BairesDev developers can get valuable insights and suggestions to improve web pages and, in this case, PWAs. Thus, we can work on the speed of your Progressive Web App but also on other key factors, including:

  • 1_soak_BDev_SRP_Numeros
    Security
  • 1_soak_BDev_SRP_Numeros
    Responsive design
  • 1_soak_BDev_SRP_Numeros
    Offline performance
  • 1_soak_BDev_SRP_Numeros
    Push notifications
  • 1_soak_BDev_SRP_Numeros
    Caching
  • 1_soak_BDev_SRP_Numeros
    User experience

What technologies do we use?

Developing PWAs means using several key technologies to guarantee the best quality results. BairesDev web engineers don’t only have the skills and expertise regarding all of those technologies but they also have the necessary experience to tackle the development of any PWA you might have in mind, regardless of the industry you’re working on.

  • React

    React

    React is one of the leading frameworks for frontend development and the value it provides to all of our PWA development projects is clear proof of why. Through React, our engineers can create rich Progressive Web Apps taking full advantage of its component-centered approach, which makes components highly reusable. Besides, the ability to turn PWAs built with React into native apps via React Native makes it a highly appealing alternative for developers.

  • Angular Developers

    Angular

    Another JavaScript framework, Angular is a mature alternative that offers a full package for PWA development. Thanks to its built-in Angular Service Worker script, the framework can create PWAs via JSON configurations instead of developing the application from the ground up. This considerably reduces the time to market while still providing the best quality results.

  • Ionic Technology logo

    Ionic

    Ionic is a highly flexible framework that can even use features from other frameworks (including React, Angular, or Vue) to build PWAs. One of the main reasons why we use Ionic is that it comes with a rich PWA toolkit that includes plenty of features and tools, including UI components, unit tests, and pre-built routing, as well as over 250 plugins for adding native device functionality.

  • Progressive Web Applications (PWA) 2

    AMP

    Accelerated Mobile Pages (or AMPs) have been around for quite a while now, aiming to provide an almost instantaneous loading speed and a quicker overall experience. Combining them with PWAs (and, more specifically, with some of its features) allows us to provide a faster and virtually seamless experience for web pages with increased complexity.

Why use Progressive Web Apps, after all?

Reviewing some of the benefits for businesses, clients, and developers we cited above, it becomes very clear that PWAs are worth looking into. But those reasons are better understood when you grasp the context in which they have risen. Consider the following:

  • 1
    More than half of U.S. individuals (51%) downloaded 0 apps per month
  • 2
    Almost half of the users expect a page to load in 2 seconds or less
  • 3
    Mobile devices accounted for 56% of organic search engine visits in 2020
  • 4
    11% of companies already have PWAs and 24% are planning to invest in them

These stats tell us that people are increasingly using their mobile devices to browse the web and are willing to spend time on content they discover through organic searches but they are, at the same time, shying away from native apps. All of that presents an unmissable opportunity for PWAs, a chance roughly more than 10% of companies are already taking. How come?

  • 1_soak_BDev_SRP_Numeros
    PWAs are fast – they take less than 1 second to load, which is 4X faster than a regular page. What’s more, they also work surprisingly fast in offline mode.
  • 1_soak_BDev_SRP_Numeros
    PWAs are cost-effective – they can work in any operating system and device, so you only have to invest in one single development.
  • 1_soak_BDev_SRP_Numeros
    PWAs are SEO-friendly – these apps rank in search engines and have an impact on rankings, so well-built PWAs are easily discoverable by organic traffic.

Use Cases

Given that PWAs are like apps, virtually any company from any industry can leverage them. In fact, that’s precisely what’s already happening. As a quick Google search can show you, there are notable uses across many fields ranging from the ecommerce and the travel sectors to social media and the retail industries.

Some of the uses they have given PWAs include:

  • 1_soak_BDev_SRP_Numeros
    User experience improvements
  • 1_soak_BDev_SRP_Numeros
    Loading speed increases
  • 1_soak_BDev_SRP_Numeros
    Bounce rate decreases
  • 1_soak_BDev_SRP_Numeros
    Conversion rate boosts

Among the companies that have already developed their own PWAs, you can find renowned companies like Twitter, Pinterest, Alibaba, Tinder, and Trivago, to name a few.

Frequently Asked Questions

A progressive web application (PWA) is a type of webpage or website that’s delivered through a web and that’s built using common web technologies like HTML, CSS, and JavaScript. It’s a platform- and device-agnostic application that allows users to run it on their browsers regardless of the operating system they are using. It’s also worth noting that a PWA is a mixture of a web and a native app, and aims to combine the best of both worlds. Thus, you don’t need to install it to use but can still interact with it as if you were using a traditional app.

Though not as popular as they should be, a lot of big companies and well-known businesses are already on board the PWA bandwagon. Some of the most renowned names include Twitter, Forbes, AliExpress, Medium, and The Weather Channel, among many others.

Some years ago, Twitter noticed that its users were having many issues when using their mobile site. From slow mobile networks to lack of storage space for cache, mobile visitors weren’t engaging with the social media’s mobile site. That’s when they built a PWA to offer instant loading, lower data consumption, and numerous native features with offline capabilities.


The results were a huge leap forward for the platform: 20% drop in bounce rate, 65% rise in pages per session, and 75% rise in Tweets sent. Additionally, the PWA takes only 600KB of space, much less than the native Android app (23,5MB)

Though there are plenty of benefits to using Progressive Web Apps, that doesn’t mean they are always the solution for your mobile strategy. It all depends on your needs, goals, and overall business. Depending on your industry and where you are as a company, PWA can be the perfect solution or a shot in the foot.


As a rule of thumb, you should use PWAs if you’re just starting your business, are beginning to explore the mobile possibilities within your industry, have a limited budget, or are looking to boost your SEO efforts. Naturally, these aren’t the only moments where a PWA can come in hand. Your best bet is to get a professional assessment that can help you define whether PWAs are right for you.
