How Much Does a Progressive Web App Development Cost?
The cost of PWA development is a highly individual matter. Considerations range from the condition of the original website to the necessary post-release improvements. Furthermore, the price varies depending on the agency you choose to engage with. Rates will, first of all, correlate with the team's expertise. As a result, you may anticipate hourly prices that range from 25 to 70 USD.

Are There Any Notable Performance Considerations for PWAs?
After receiving permission, native apps are granted full access to the device's hardware and can use all of its features. PWAs could run into some limits, either because iOS/Android purposefully put them in place or because of technical constraints of systems.
There are certain restrictions with access to the GPS, camera, calendar, mobile payments, fingerprint sensor/Face ID, and other features. Their level of access is determined by the OS. Android, for instance, refreshes its environment more quickly than iOS. It concerns push notifications as well. They are functional on Android and operate in Chrome, Opera, and Mozilla; however, there are still some issues with iOS and Safari.
Another issue is that cached files expire quickly. The previously downloaded files will disappear if users don't open the PWA for a while, yet the shortcut will remain. However, the PWA regulations change over time; it’s growing its capabilities and winning more and more trust.
Note: A PWA may require verification during service worker updates, content caching, and app installation. The ""verification successful"" waiting process may be quite long due to the size of updates, network conditions, device performance, and more.
What Are the Benefits of PWAs?
When building an online presence, many businesses create apps for mobile devices, which often includes developing native and web applications. Sometimes, companies even choose to create progressive web apps rather than native apps, but why? Here are the most prominent advantages PWAs provide:
- High Speed
Fast loading is possible thanks to service workers, ensuring advanced caching, and GraphQL as API. By using these technologies, PWAs operate almost as quickly as native applications. - Excellent UI/UX
The PWA code is compatible with numerous platforms, including desktop, iOS, and Android. PWAs may adapt to the OS and show native-like components due to the flexible interface. Regarding button placement, menus, navigation, and other aspects, the solution adheres to standard native app features. As a result, PWAs visually remind native apps while working from the browser. - Lightweight and Easily Discoverable
PWAs use memory only for the cache. They weigh less than 1 MB, don't need a specific location in the device memory, and may alter in size as needed. Additionally, search engines may index PWAs like ordinary web pages, increasing your company's visibility. - Cost-Effective
It takes two distinct codes to make a native app accessible to both iPhone and Android users. Native app developers are key in this process, creating solutions in Swift for iOS and in Java or Kotlin for Android. PWAs, on the other hand, work with all mobile browsers and OSs, so you need two times less effort to create one. Additionally, you'll get a bonus of the site's enhanced desktop version by redesigning it as a progressive web app. - Operates Offline
Without the internet, traditional websites would not be accessible. PWAs are similar to native applications in this regard because they both function without an Internet connection. PWAs employ Vanilla JavaScript, React, Angular service workers, and others to cache data and enable user browsing. Naturally, offline functionality is constrained; for instance, you cannot finish an order or send a message. However, customers may still add items to their shopping carts or read their message history, and the web page will refresh once the connection is restored. - Installability
Native applications need to be downloaded and installed from app stores. Yet, they are pretty heavy. Therefore, before downloading any of them, people tend to hesitate. Aside from that, consumers eventually need to get rid of certain native mobile apps because they gradually eat up more and more storage space, and your app may be among those. The key with PWAs is that, unlike native apps, a web app icon may display on the home screen without really being downloaded.

Based on what I read, it seems like it just a variant of hybrid apps. Is this correct?
There is not much information about this on the internet.
Are Twitter/Instagram/Facebook apps actually PWAs packaged into native apps? Are there other notable examples?
I'm just kinda thinking it is a bit of a kludge. Having said that I'm building a website and having info about whether to support PWA would be useful.
The concept of the progressive web app (PWA) was approached by Google in late 2015. They are basically web applications (Website) but have look and feel like other native mobile apps. The progressive web app enabled websites can offer functionalities such as working offline, push notifications, and device hardware access.
Benefits of the progressive web app:
1. Smaller and Faster: The progressive web apps are much smaller in size than native apps. They don’t even need to install. That’s they are not wasting disc space and load very fast.
2. Responsive Interface: Progressive web app (PWA) supported web pages are capable to fit in every screen sizes automatically. It could be a smartphone, tablet, desktop or laptop.
3. No Updates Required: Most of the mobile apps need regular weekly updates. Like the normal website, progressive web apps (PWA) are always loaded latest updated version whenever the user interaction happens and no App or Play Store approval required.
4. Cost Effective: Native mobile apps need to be developed for both Android and iOS devices separately and their development cost is very high. On the other hand, progressive web apps are had the same features but the fraction of the prior price.
5. SEO Advantage: Progressive web apps are discoverable by search engines and load super-fast. Just like other websites, their links are sharable too. This, in other words, gives good user experience and result in SEO rank boost.
6. Offline capabilities: Due to the support of service worker API, PWAs are accessible in offline or low internet connections.
7. Security: PWAs are delivered over HTTPS connection and secure user-data over each interaction.
8. Push Notifications: By the support of push notifications, PWAs can interact easily with the users and provide a really amazing user experience.
9. Bypass the app stores: PWAs don’t need the App store or Google play store support. Their updated version can be directly loaded from the web server without the requirement of app store approval. On the other hand, native apps need days of approval if any new update required. There are possibilities of getting rejected or banned.
10. Zero installation: During browsing, progressive web app gets its own icon on phones and tablets, just like a mobile application, but without the need to go through the tedious and slow App Store installation process.
Disadvantages of the progressive web app:
1. Less access to system features: Currently, Progressive Web Apps have limited access to native system features than native apps. Also, all browsers are not supporting its full features but maybe in near future, it will be the new standard of development.
2. More Android – Less Apple’s iOS: progressive web apps are currently, most supported by Android devices. Apple’s iOS is only partially supporting.
3. No review standard: progressive web apps don’t need any kind of review system which is applicable for native apps from the app store. It may make the process faster but lack of promotional benefits from the app store.
Progressive web app checklist: The checklist for the progressive web app is extensive. I have described its main few items here. 1. HTTPS 2. Web app manifest - manifest.json 3. Service worker 4. Responsive design 5. App icon 6. First load fast even on 3G
Conclusions: There are huge possibilities offered for the progressive web app. Although there are lots of features and browser adaptability expected in near future. But, whatever already exists in the market is enough to show a strong mobile presence.

A PWA is a website with certain progressive features, most notably the ability to load offline or in areas with spotty connection, load quickly, display push notifications, and have other native app qualities. The benefits of a PWA is that they run on any browsers (since they're a normal website, if the browser doesn't support PWAs then the user gets a normal website experience), even desktop browsers. On mobile devices, the user will often get prompted to install the web app to the home screen, which happens almost instantaneously and uses barely any data since the website is already loaded. This allows for way more "downloads" than a native app, leading to higher engagement. For another brief overview of what a PWA, Google has some great articles about them.
Technically speaking, a PWA is a website that has two things: a web app manifest file and a service worker.
A manifest is a JSON file (usually called manifest.json) with some information about the progressive web app. It contains information similar to what you would include with a native app. It has the name, the short name for display on home screens, icons, orientation, etc. A web app manifest can be used on any site (even non-PWAs) to give the browser more information and allow the site to create a shortcut on the user's homescreen, but it's required for a PWA. You can read more about it over on the Google Developer's site.
A service worker is a JavaScript file that can be installed by the browser to do certain tasks. This file will be run in the background of the site and can do things like caching resources, intercepting network requests (to do stuff like return data from the cache), receiving push notifications, background synchronization, etc. When a user first visits your site this JS file gets installed and starts running. This is the file that allows for things like offline functionality. You can read more about service workers on the Google Developer's site as well.
