Web app vs native app vs PWA: which one should your product be?
It is not a contest between technologies: it is a question about where your users are and what their phone has to do for them.
What is the difference between a web app, a PWA and a native app?
The difference is where the product runs and how it reaches people: a web app opens in the browser, a PWA is a web app that installs on the device, and a native app is downloaded from a store and written for the operating system. In between sit hybrid apps, which wrap a web codebase inside a store app.
- PWA (progressive web app)
- A web app that uses modern browser APIs to behave like an installed app. As web.dev explains, installing one moves it out of the browser tab into its own window, launched from the home screen, dock or taskbar like any other app.
| Web app | PWA | Hybrid app (e.g. Capacitor) | Native app | |
|---|---|---|---|---|
| How users get it | A link in the browser | A link, then install to the home screen | App Store and Google Play | App Store and Google Play |
| Codebase | One web codebase | One web codebase | One web codebase plus a native shell | One project per platform, or a cross-platform framework |
| Updates | Instant | Instant | Normally go through store review | Every release goes through review |
| Push notifications | From the browser on desktop and Android; not on iPhone | Yes; on iOS only once added to the home screen (iOS 16.4 onwards) | Yes, native | Yes, native |
| Device features | Limited | Growing, varying by browser | Broad, through plugins | Full |
| Selling digital content | Web payments | Web payments | Store rules (in-app purchase on iOS) | Store rules (in-app purchase on iOS) |
| Best fit | B2B SaaS, back-office tools, desktop use | Frequent phone use with no need for the stores | Store presence from a single codebase | Heavy graphics, peak performance, deep system features |
When is a web app enough?
A web app is enough when the product is used mostly on a computer, in working sessions, and needs neither notifications nor phone features. That covers much of B2B SaaS, back-office software and internal tools; a responsive layout handles quick check-ins from a phone.
Early on the advantage is large: one codebase, instant updates with no review queue, no store commission on payments taken on your own site. If you are building a SaaS, it is the starting point described in how to build a SaaS product.
What can a PWA do, and what can't it?
A PWA can be installed to the home screen, open in its own window, work offline through caching and send notifications. It does not sit in app stores as naturally as an app does, and its access to some system features is more limited, with differences between browsers and operating systems.
The iPhone is the case everyone asks about. WebKit, the engine behind Safari, announced in February 2023 that with iOS and iPadOS 16.4, web apps added to the Home Screen can receive push notifications, provided permission is requested in response to a user action such as tapping a button. The same release added the Badging API for app icon counts.
iOS 16.4
The practical catch is the install step: on an iPhone, users must add the PWA to the Home Screen themselves, and many do not know how. If notifications are the heart of your product, measure how many users actually complete that step before you bet on it.
When do you need a native or hybrid app?
You need one when the product's value depends on the phone: dependable notifications, heavy offline use, camera, sensors, Bluetooth, selling subscriptions inside the app, or users who look for products like yours in the stores.
Between fully native and hybrid, hybrid is often the better trade-off for a startup. Capacitor describes itself as a cross-platform native runtime that runs web apps natively on iOS, Android and more, so the codebase stays your web app's. The cross-platform options are compared in React Native vs Flutter vs Capacitor.
How do cost and time differ between the three routes?
They differ mainly with the number of codebases and distribution channels you maintain. A web app or PWA has one codebase and no review queue; a hybrid app has one codebase and two stores; fully native can mean three separate projects, web included.
- Stores: the Apple Developer Program costs $99 a year and a Google Play developer account $25 one-time (October 2026), plus the time for listings, screenshots and reviews.
- Releases: every app version goes through store review, so a bug fix that ships in minutes on the web takes longer in the app.
- Payments: on the web you pay only your payment provider; inside iOS apps, digital content brings in-app purchase and Apple's commission into play.
- Skills: more native platforms mean more specialists, or a team that covers them all.
The full set of line items is in SaaS development cost and, for apps, in how much it costs to build an app. The underlying technical choice is covered in the best tech stack for a startup MVP.
How do you choose in practice?
You choose by answering five questions, in this order: our own sequence, meant to settle the question before you ask anyone for a quote.
Five questions
Will people use it mainly on a computer?
If so, start with a responsive web app. Everything else can wait.
Are notifications essential?
If they are occasional, a PWA may do; if they are the core of the product, especially on iPhone, consider an app.
Do you need device features the browser handles poorly?
Bluetooth, sensors, heavy offline work: here an app is close to mandatory.
Do your users look for products like yours in app stores?
For many consumer products, an App Store and Google Play listing is part of discovery and trust.
Can you afford to maintain several platforms?
If not, pick a route that starts from one codebase: web, PWA or hybrid.
For many startups the answer comes in stages: a web app now, a PWA when installation matters, a hybrid app when notifications and store presence become necessary. Each stage reuses the work of the one before.
Frequently asked questions
Can a PWA be published on Google Play and the App Store?
On Google Play, yes: a Trusted Web Activity opens your PWA inside an Android app that you publish like any other. On the App Store you need a real app, for instance a Capacitor shell, offering more than a repackaged website, as Apple's guideline 4.2 requires.
Do PWAs work offline?
Yes, if they are built to: they cache resources and some data locally, as MDN's PWA guides describe. How much works without a connection depends on how the app is designed; it is not automatic.
Do push notifications work for a PWA on iPhone?
Yes, from iOS and iPadOS 16.4, but only if the user has added the web app to the Home Screen and granted permission after an explicit action, such as tapping a button.
Is a hybrid app slower than a native one?
For most business apps, built from dashboards, forms and lists, users will not notice. It shows in games, intensive 3D graphics or very complex animation, where native has the edge.
Can I launch with a web app and build the mobile app later?
Yes, and it is often the most prudent route for a startup. A well-built web app lets a hybrid app reuse most of it, so choose a compatible stack from the start. When the time comes, the steps are in how to publish an app on the App Store.
