Some examples of web applications include Gmail, Google Docs, Facebook, and more. The code for web apps is stored on the server and then rendered in the user's browser. This makes web apps highly portable across different devices and operating systems.
Desktop applications offer several advantages compared to web applications:
1. Faster performance
Desktop applications run natively on your computer system and don't need to transfer data over the internet. This makes them much faster than web apps, which rely on network connections. Desktop apps can respond instantly to user input without any lag or delay. This results in a smoother experience, especially for graphics, video, and gaming applications.
2. Ability to work offline
With desktop applications, you aren't dependent on an internet connection to use the software. Desktop apps can work offline once they are installed on your computer. This makes them more reliable and enables productivity even without connectivity. Web apps require constant internet access to function.
3. More control over the software
Users have more control over desktop application software and settings. You can customize desktop apps to suit your preferences. With web apps, you are limited to the options provided by the developer. Desktop apps give power users more flexibility.
4. Often more feature-rich
Desktop applications offer more extensive features compared to web apps. This includes specialization for industries and integration with other desktop software. The scope of desktop apps is broader since developers aren't limited by internet compatibility. Web apps provide more general functionality.
Factor 1. Accessibility
Web applications are far more accessible and can run on any internet-connected device with a browser, from desktop computers, laptops, tablets, and smartphones. Users only need to access the web app's URL to use it. This allows employees to work flexibly from multiple devices and locations.
In contrast, each computer or device must install desktop applications locally. They are limited to running on the specific machine where users downloaded and installed the software. Employees can only access the desktop app from their work computer or device it is set up on, limiting accessibility and flexibility.
Factor 2. Performance
Desktop applications generally offer faster performance and are more responsive than web applications. This is because desktop apps run natively on the device, fully utilizing the device's computing resources and hardware.
In contrast, web applications must send requests and data to remote servers online. This can introduce latency issues that degrade performance. The speed of the user's internet connection significantly impacts the responsiveness of web apps. Slow internet connections lead to increased loading times and laggy performance.
Desktop applications can quickly access and render graphics, multimedia, and large local datasets without streaming them over the network. Complex computations and workflows generally execute faster locally on desktop hardware than on web applications.
Nevertheless, web application performance has improved dramatically thanks to faster internet speeds and optimization techniques like caching and compression. For less intensive tasks, modern web apps can approach native app performance. However, a local desktop application still provides a noticeably faster and smoother experience for graphically or computationally intensive apps.
Factor 3. Updates and Version Control
Web applications are updated continuously without any effort from the user. The updates happen seamlessly in the background, so users access the most recent version whenever they load the app in their browser. This means new features, fixes, and improvements are rolled out rapidly.
The continuous deployment model of web apps allows vendors to iterate and ship incremental improvements rapidly. Desktop applications have a more cyclical update pattern based on major desktop version releases. This means big batches of changes rather than a constant stream of little enhancements.
Factor 4. Offline Use
Desktop applications can work offline without an internet connection, making them useful when internet connectivity is limited or unavailable. Once the application is installed locally on a computer or device, the user can launch and use it anytime without needing to connect to the internet or web server. This makes desktop applications ideal for use on airplanes, in remote locations, or anywhere that internet connectivity is unreliable.
In contrast, web applications require constant connectivity and an internet connection. The application code runs on a remote server, so an active network connection is necessary for the client device to access the application, load pages, and save data. Loss of connectivity will disrupt the usage of a web application.
This limitation makes web apps challenging to use in offline scenarios. Regardless, web apps benefit from central hosting - changes get updated for all users with an internet connection.
Factor 5. Collaboration
Web applications make collaboration much easier compared to desktop applications. With web apps, documents and files are stored in the cloud, allowing multiple users to access and edit them from anywhere. This enables seamless collaboration between team members, even in different locations.
Web apps like Google Docs, Dropbox Paper, and Notion provide built-in collaboration features like commenting, version history tracking, and real-time co-editing. Desktop applications lack these capabilities - designed for single users working independently on local files.
Sharing and syncing files between desktop app users requires manual steps like email attachments or external cloud storage services. There is no real-time collaboration where multiple users can work on the same document simultaneously.
The centralized nature of web apps removes collaboration friction. Desktop users must combine changes and deal with version control issues manually. Web apps handle merge conflicts seamlessly behind the scenes. Their access controls also allow managing user permissions easily. With desktop apps, such permissions need manual setup per machine.
Factor 6. Security
Web applications are inherently more vulnerable to security threats because they are accessed over the internet. Hackers can exploit vulnerabilities in a web app's code or server to gain unauthorized access. Web apps rely on username/password systems prone to phishing and hacking.
Factor 7. Cost
Web applications typically require monthly or annual subscription fees to use the software. This can add up over time, especially for larger organizations. Desktop applications are usually purchased once for a one-time fee and can be used indefinitely without further charges.
With a web application, the developer bears the responsibility and cost for hosting, maintenance, updates, etc. With a desktop application, that cost shifts to the end user.
Some key differences:
- Web applications require recurring fees, and desktop applications are a one-time purchase
- Web app pricing often scales with the number of users or features; desktop apps have fixed costs
- Companies must budget for ongoing SaaS spending with web apps
- It can be costly for web apps to handle large data sets or traffic
- Desktop apps put hardware/update costs on the user
- Web apps centralize costs with the vendor/developer
Web applications require more long-term investment, while desktop apps involve more considerable up-front expenditure but less recurring costs after that. Companies should factor these pricing structures into their evaluation.
Factor 8. Customization
Desktop applications offer far more customization options compared to web applications. Users can customize the user interface and experience in a desktop app. The code is run locally, so developers can expose user preferences to enable custom themes, layouts, widgets, and more.
Web applications limit customization to the options exposed by the application provider. The code runs on remote servers, so users have no direct access. Web apps may allow interface skins and themes from a pre-selected set of options, but advanced customization is impossible. Users are restricted to the functionality and flexibility provided by the vendor.
The open-ended customization of desktop apps empowers users but requires more technical skill. The constrained options of web apps offer simplicity for most users but less flexibility for power users. Companies building web apps are hesitant to enable deep customization that could break the app experience.
Factor 9. Platform Support
Web applications have the advantage of broad platform support and compatibility. They are designed to run within a web browser, which provides a consistent interface across different platforms, including Windows, Mac, Linux, iOS, and Android.
Users can access a web app seamlessly if the device has a modern web browser and internet connectivity. The multi-platform nature of web apps makes them highly accessible.
Desktop applications run natively on a specific operating system like Windows or macOS. They must be specifically developed and compiled for each platform. Desktop apps also rely on underlying system hardware, which can limit compatibility.
For example, a Windows desktop application will only work on Windows PCs. A Mac user would not be able to run that same desktop app. The compatibility requirements make desktop applications less accessible across different platforms.
The cross-platform flexibility of web applications gives them the advantage for deployments where broad device and operating system support is needed. Desktop applications are best suited for use cases requiring tighter platform control and hardware optimization.
