For most new software, the default answer is a web app: one URL, no installer, updates the moment you deploy. But the default is not always right. The desktop app vs web app decision still matters for tools that work offline, handle large files, talk to hardware or need to feel instant all day long. Get it wrong and you either fight the browser for years or pay to maintain installers nobody needed.
This guide sets out where each approach wins, the hybrid options that now blur the line, and a checklist you can use to decide before any code is written.
Desktop app vs web app: the core difference
A web app is software delivered through a browser. The code lives on your servers and users reach it with a link. A desktop app is installed on the user's computer and runs there, with direct access to the operating system, the file system and connected devices. Either can talk to a backend in the cloud; the difference is where the interface and the processing live.
That difference drives everything else: how you ship updates, how users find and install the product, what it can do without a connection, and what it costs to support across Windows and macOS.
Where a desktop app still wins
- Offline and unreliable networks. Field teams, factories, labs and ships cannot depend on a connection. A desktop app keeps working and syncs later.
- Large files and local processing. Video, audio, CAD, imaging and big datasets are faster to handle on the machine than to upload and process remotely.
- Hardware access. Barcode scanners, label and receipt printers, lab instruments, serial devices and specialist peripherals are far easier to control from native code.
- Deep operating-system integration. Background services, system tray tools, global shortcuts and tight file-system workflows fit desktop naturally.
- All-day power users. People who live in one tool for eight hours notice every delay; a native app can feel faster and more predictable.
Where a web app wins
- Distribution. A link is the lowest-friction install there is. Sales demos, trials and onboarding are simpler when nothing has to be downloaded.
- Instant updates. You deploy once and every user is on the new version. No one is stuck on a release from last year.
- Cross-platform by default. Windows, macOS, Linux, Chromebooks and tablets all run a browser.
- Lower support cost. One environment to test, and fewer "it works on my machine" problems.
- Discoverability. Public web pages can be found in search, and every screen can have a shareable URL.
Desktop app vs web app, side by side
| Desktop app | Web app | |
|---|---|---|
| Installation | Download and install per machine | None; open a URL |
| Updates | Shipped to each install; users may lag behind | Deployed once for everyone |
| Offline use | Strong by default | Limited unless built as a PWA |
| Hardware and files | Full access through the operating system | Restricted by the browser sandbox |
| Platforms | Build and test for Windows and macOS separately | Any modern browser |
| Distribution trust | Code signing, notarization or app stores | HTTPS and your domain |
| Typical fit | Offline, hardware, heavy files, power users | Collaboration, SaaS, portals, dashboards |
The middle ground: PWAs, Electron and Tauri
You no longer have to treat desktop app vs web app as a choice between two extremes. Three approaches let a web codebase behave more like a desktop app.
Progressive web apps
MDN describes a progressive web app as an app built with web platform technologies that provides a user experience like that of a platform-specific app. PWAs can be installed, work offline, run tasks in the background and integrate with the operating system for things like notifications and file associations. They are the cheapest step toward desktop, but they still live inside the browser's limits.
Electron
Electron packages a web app as a real desktop application by embedding Chromium and Node.js into its binary, so one JavaScript codebase runs on Windows, macOS and Linux. You get file-system and OS access that a browser cannot offer. The trade-off is size and memory, because every app ships its own copy of a browser engine.
Tauri
Tauri takes a lighter route. Instead of bundling a browser, it uses the web view already available on each user's system, and its documentation says a minimal Tauri app can be less than 600KB. Backend logic is written in Rust, with options for Swift and Kotlin, which suits teams that want web-based UI with native-level performance for the heavy parts.
Distribution, signing and updates on Windows and Mac
Shipping a desktop app means earning the operating system's trust. On macOS, a Developer ID certificate lets Gatekeeper verify you as a trusted developer when people download your app from outside the Mac App Store, and Apple's notary service scans Developer ID-signed software and issues a ticket that Gatekeeper checks. On Windows, code signing plays a similar role in how the system and users judge an installer. Budget time for certificates, signing in your build pipeline and an auto-update mechanism, or users will run old versions indefinitely.
Web apps skip most of this. The equivalent work is HTTPS, a sound deployment pipeline and monitoring, which our cloud and DevOps practice sets up as part of most builds.
Cost and maintenance over time
On cost, the desktop app vs web app comparison usually favors the web. A single web app is usually the cheaper product to build and to keep running, because there is one codebase and one deployment target. Native desktop apps for both Windows and macOS mean two platforms to design, test, sign and update, unless you use a cross-platform approach such as Electron, Tauri or Flutter. If mobile is also on the roadmap, the framework choice gets more important; our comparison of React Native and Flutter covers the mobile side, and the mobile app cost guide explains how scope and platforms drive budget.
A quick decision checklist
- Must it work fully offline? If yes, desktop or a PWA with a strong offline design.
- Does it control hardware or large local files? If yes, desktop, native or Electron/Tauri.
- Do users need access from any device, including phones and shared computers? If yes, web.
- Will you onboard many users quickly, or sell through trials and demos? If yes, web first.
- Is the team strongest in web technology? Consider web plus a hybrid shell before fully native.
- Is speed for all-day power users the main selling point? Prototype the heaviest workflow natively before deciding.
Build it on the right platform the first time
We build custom Windows and Mac desktop apps as well as Android and iOS apps and web apps, so we have no reason to push you toward one of them. In discovery we map how people will actually use the software, where it runs and what it connects to, then recommend web, desktop, hybrid or a mix, with a priced plan and no obligation.
Our web, desktop and mobile development team works with senior engineers, weekly demos and working software from the first week, and you own all code and IP from day one. If you are weighing a desktop app vs web app for a new product or a rebuild, tell us what you are building and a senior engineer will reply within one business day.
Frequently asked questions
What are the disadvantages of desktop apps?
They must be installed and updated on every machine, so users can fall behind on old versions. Supporting both Windows and macOS means more testing, plus code signing and notarization work. They are also harder to trial, share and access from phones or shared computers than a web app.
How to turn a web app into a desktop app?
The lightest option is to make it a progressive web app, which users can install and run offline. For deeper access to files and the operating system, wrap it with Electron, which embeds Chromium and Node.js, or Tauri, which uses the system's own web view. Either way, plan for offline behavior, signing and auto-updates.
Is it better to use an app or the website?
It depends on how often you use it and what it needs to do. For daily, heavy or offline work, an installed app is usually faster and more capable. For occasional use, or when you switch between devices, the website is simpler and always up to date.
Why is everything a web app now?
Because web apps are easier to distribute, update and support. One deployment reaches every user on every operating system, there is nothing to install, and tools like PWAs and Electron now let web code do much of what used to require native desktop development.
Is Electron a desktop app or a web app?
Both, in a sense. An Electron app is built with web technologies but ships as an installed desktop application that bundles its own browser engine and Node.js. Users experience it as a desktop app, with file-system access a normal website does not have.
