People have changed, their behavior towards mobile technology has changed with time, or it’s rather better if we say ‘evolved’ instead of changed. In recent past years, app development has gradually taken over web development (not completely). Businesses who own a website are now considering investing in mobile app development to win a competitive advantage over others.

  • PWAs cost four times less than the native mobile apps along with one-third less app maintenance cost.

What are Progressive Web Apps?

Progressive web apps are website apps that look, feel, and act like a native mobile app in a lightweight version. These apps use technologies like HTML5, CSS3, and JavaScript. Deployed on the cloud server, PWAs combine both web apps and mobile apps’ functionality and features and can easily be accessed through the URLs.

In simpler words, PWAs are hybrids of regular websites and mobile apps. Along with PWAs offering several benefits over native apps, they also overcome the main disadvantages of using a browser for online surfing and provide an app-like customer experience. Google Chrome, Opera, Safari, Samsung browser, and others support PWAs.

  • Progressive – As the name says, a progressive web app must work on any device, platform, and browser. Its progressive enhancement makes PWAs stand out from traditional apps.

  • Discoverable – Being a website, PWAs are easily discoverable in search engines. This is one of the biggest advantages of choosing PWAs over native apps.
  • Linkable – PWA uses the Uniform Resource Identifier (URI) to indicate the application’s current state, enabling the web app to reload its state when the user shares the app’s URL.
  • Installable – A progressive web app can easily be installed on the device’s home screen, making it readily available for users on desktop and mobile phones, just like an app.
  • Secured – PWAs are hosted over HTTPS to prevent man-in-the-middle attacks and making the user experience more seamless and secure than native apps.
  • Connectivity-Independent – PWAs eliminate the connectivity-independence and allow users to use them despite limited or no internet connection, making it the PWA’s biggest trait.

Service Workers

Served Over HTTPs

A PWA needs to be served over a secure network so that hackers can’t brute-force. Cloudflare and LetsEncrypt provide you with an SSL certificate.
