( faq )
Questions buyers ask
What is a Progressive Web App?
A PWA is a website enhanced with app-like capabilities like offline support, push notifications, and home-screen installation, delivered through the browser.
What makes a site a PWA?
The core requirements are HTTPS, a web app manifest for installability, and a service worker that enables offline and background behavior.
PWA or native app: which should I choose?
PWAs are cheaper and cross-platform with no store approval. Native apps offer deeper device access and store distribution. You can often combine both.
Can a PWA be indexed by search engines?
Yes. PWAs are still web pages, so they are crawlable and linkable, which is an advantage over native apps for discovery.
Is a PWA right for my business?
PWAs suit content sites, eCommerce, and tools that value fast load, offline, and installability without a full native build.
Can Udaan build a PWA?
Yes. We add PWA installability, offline support, and performance to web builds, and can pair a PWA with a native app when useful.
