When Should You Build a Native Desktop App or a Web-Based UI
359Many people think of a desktop application as a program with a graphical interface that runs natively on your computer. But today, a lot of so-called desktop apps are just web pages running inside a standalone browser. That’s not necessarily a bad thing. Using web-based UIs allows developers to tap into a huge library of existing web components and tools, making UI design easier and more flexible. Still, there are times when building a native desktop app makes more sense, even if it requires more effort.
What’s a Native Desktop App Anyway?
A native desktop app is one that uses the computer’s built-in interface tools or a third-party cross-platform toolkit not primarily based on web technology. For example, some popular apps like Visual Studio Code or Slack are built with Electron or Tauri, which use HTML, CSS, and JavaScript for the front end. These are technically web-based apps packaged to run on your desktop. On the other hand, full applications like Microsoft Word or Adobe Photoshop are true native apps. They don’t rely on web technology but instead use the operating system’s native UI components or dedicated frameworks.
Some native apps have been around for a long time, built before web UIs and Electron existed. Many companies prefer to keep their legacy apps as they are, especially if they’re stable. But native apps also offer more control over how the user interacts with the software, which can lead to a better experience. The trade-off is that they usually take more time and effort to develop and maintain.
The Upsides of Web-Based Desktop Apps
The biggest advantage of web UIs is access to a vast ecosystem of ready-made UI elements. Whether you need simple forms or complex interactive charts, chances are good that web versions already exist. Web components are often easier to implement because they’re designed to be portable and reusable. This means developers can rapidly put together a user interface using existing libraries and frameworks, saving time and effort.
Another big plus is portability. Web UIs can run across different operating systems without needing major changes. The browser handles many of the platform-specific details, like clipboard access or window management. This makes deploying updates easier and quicker because you mainly need to update the web code, not the entire app.
Challenges of Using Web UIs for Desktop Apps
Despite their advantages, web-based desktop apps come with some downsides. The biggest is dependency on the web browser. Many Electron apps bundle a full browser engine, which can add hundreds of megabytes to the app size—even for simple programs. Some developers try to reduce this by using the native web view available on the platform, like WebView on Windows or macOS. But this approach can introduce compatibility issues because these web views may lag behind the latest browser features.
Interactions between the UI and the app’s core functions are also limited by what the browser can support. Usually, communication is done over a network-like connection, which can introduce latency and slow down real-time updates. For performance-heavy tasks, some developers try to move processing into the browser using WebAssembly, but that adds complexity and build steps.
Deciding Which Approach Fits Your Needs
Choosing between a native app and a web UI depends on what’s most important for your project. If your app doesn’t need to be web-based, or if size and performance are critical, a native app is often the better choice. For example, lightweight command-line tools or apps that need minimal system interaction can be simpler and faster to develop as native applications. They also tend to run with less latency and offer more direct control over hardware and system features.
Web UIs make sense when you want easy cross-platform deployment and rapid development. If your app needs frequent updates, or if you rely heavily on web components, a web-based desktop app can save time. They’re also useful when you don’t require ultra-low latency or real-time performance, as browser-based apps can introduce delays due to network or rendering constraints.
In the end, the line between native and web apps is blurring. The web has become a powerful platform for building complex applications, but traditional desktop apps still hold advantages for certain use cases. Weighing the benefits and limitations of each approach helps in choosing the right path for your project.
