What a desktop app development company builds
A desktop app development company builds software that installs and runs on a computer instead of in a browser tab. Desktop apps can work offline, read local files and connect to printers, scanners and other hardware. They also stay open all day without browser limits.
Kwebby builds internal tools for operations teams, point-of-sale and kiosk apps, file processing utilities and commercial software that companies sell to their own customers. Each project starts with a list of target operating systems and a fixed quote.
Many clients already run a web app and want a desktop version with offline mode or hardware access. Kwebby can reuse much of the existing web code in an Electron or Tauri app.
Electron app development for cross-platform teams
Electron app development uses web technologies such as React and TypeScript to build one app for Windows, macOS and Linux. Slack, Visual Studio Code and Discord use Electron for their desktop apps. The approach suits teams that want one codebase and fast updates.
Kwebby adds native features through Electron's APIs: system notifications, tray icons, file dialogs, global shortcuts and deep links. Native Node.js modules handle hardware such as serial devices and USB scanners.
Electron apps use more memory than native apps because each app ships with its own Chromium engine. For tools that must stay light, Kwebby recommends Tauri instead.
Windows application development with .NET
Windows application development with C# and .NET fits companies that run Windows across the business. Native Windows apps start fast, use less memory and integrate with Active Directory, Windows services and Office files.
Kwebby builds Windows apps with WPF or WinUI 3 and packages them as MSIX or classic installers. You can distribute the app through the Microsoft Store, your own website or your company's device management system.
Electron, Tauri or native: how Kwebby picks the stack
Kwebby picks the stack based on your users, your devices and your budget. Each option has clear strengths.
Kwebby explains the recommendation on your first call and lists it in your quote. You approve the stack before development starts.
- Electron: one codebase for all three operating systems and a large library ecosystem
- Tauri: smaller installers and lower memory use, with a Rust core and a web interface
- .NET with WPF or WinUI: native Windows performance and deep Windows integration
- Swift for macOS: native Mac apps for teams that only use Apple hardware
Distribution, updates and security
Windows and macOS warn users about software from unknown publishers. Kwebby signs Windows installers with your code-signing certificate and notarizes macOS builds through Apple, so the operating system recognizes your company as the publisher.
Automatic updates deliver fixes and new features without asking users to download a new installer. Kwebby sets up an update server or uses GitHub Releases, depending on your distribution plan.
Kwebby stores sensitive data in the operating system's secure storage, such as Windows Credential Manager and macOS Keychain. Network traffic uses HTTPS, and local databases can be encrypted when your data requires it.
Tech we use
Frequently asked questions
How much does a desktop app cost?
Kwebby builds simple desktop utilities from $600 for one operating system with up to 3 core screens and an installer. Larger apps with local databases, cross-platform builds, cloud sync and hardware integrations add to the price. Your fixed quote lists every feature and cost before work begins.
Should I choose Electron or a native desktop app?
Choose Electron when you need Windows, macOS and Linux from one codebase or already have a web app to reuse. Choose native .NET when your users only run Windows and need top performance or deep system integration. Kwebby recommends one option after your first call.
Can you turn my web app into a desktop app?
Yes. Kwebby can package your existing web app with Electron or Tauri and add desktop features such as offline mode, file access, notifications and automatic updates.
How do users get updates?
Kwebby sets up automatic updates. The app checks for a new version, downloads it in the background and installs it on the next restart.
Can you publish my app to the Microsoft Store or Mac App Store?
Yes. Kwebby can prepare store builds and listings, or set up direct downloads from your website. Many business tools use direct downloads, while consumer apps often gain visibility from the stores.
Do I own the code?
Yes. You own 100% of the source code, build scripts and installers. Kwebby hands over the repository and signing setup at delivery, so your team can release updates on its own.
How long does desktop app development take?
Most desktop apps take 4–12 weeks. A single-platform utility can ship in about 4 weeks, while cross-platform apps with cloud sync and hardware support take longer.
