Desktop App Development

Windows · macOS · Linux

From system tray utilities to business apps that talk to hardware, we build desktop software, then sign it, ship it and keep it up to date.

At Next to Future, we build desktop apps for companies whose work the web cannot handle: Windows first, and macOS and Linux when needed. We choose native .NET (WinUI, WPF) or a cross-platform approach (Electron, Tauri) based on the need, and we own the full lifecycle, from the installer and code signing to auto-updates. Our own products, Next Windows and Next Notify, are live examples of this work.

When is a desktop app the right choice?

A web application is enough for many jobs. A desktop app earns its place when you need one of these:

  • The app must run in the background, wait in the system tray and show notifications.
  • Work has to continue when the internet connection drops.
  • You need access to printers, barcode or card readers, serial ports or USB devices.
  • You will use operating system features such as the file system, windows, system-wide shortcuts and screen capture.
  • You need to work fast with large files or heavy data locally.

If none of these apply, we say so: web application development is often the faster route and easier to maintain. When a desktop app needs a server side or an admin panel, we build both in the same project.

Which technology do we use?

We pick the technology per project, and each option has trade-offs:

  • Native .NET (WinUI, WPF): when the target is Windows only, for the closest integration with the operating system and a Windows-native interface.
  • Electron: one web-technology codebase for Windows, macOS and Linux. The ecosystem is mature; the trade-off is a larger installer and higher memory use, because it bundles a browser engine.
  • Tauri: the interface is also built with web technologies, but it uses the operating system's own web view, so packages are usually smaller.

Why do installers, signing and updates matter so much?

With desktop software, half the work starts once the app reaches the user's computer. An unsigned installer meets a security warning on Windows and macOS, and an app that does not update soon falls behind. That is why we plan the installer, code signing, auto-updates, crash reporting and, where needed, usage telemetry from the start.

Next Windows verifies the signature of each new version before installing it. Next Notify runs on Windows, macOS and Linux, waits in the system tray or menu bar and installs updates only after verifying their SHA-512 hash.

01 Scope

From Tray Utilities to Business Software

  • 01

    Tray and Background Apps

    Utilities that start with the session, wait in the system tray or menu bar, open with a shortcut and show notifications.

  • 02

    Operating System and Hardware

    Windows, file system, shortcuts and screen capture, plus access to peripherals such as printers, readers, serial ports and USB.

  • 03

    Offline Work

    Apps that store data locally, keep working when the connection drops and sync with the server once it is back.

  • 04

    Distribution and Updates

    Installer, code signing, auto-updates, crash reporting and telemetry that respects user privacy.

02 Process

From First Release to Every Update

  • 01

    Discovery

    We clarify users, target operating systems, hardware and offline needs. You get a scope and a technology recommendation.

  • 02

    Prototype

    We test the risky parts, such as hardware access or OS integration, in a small prototype and confirm the technology choice.

  • 03

    Development

    We build in short cycles and test each build on the target operating systems; you can install and try interim builds too.

  • 04

    Release and Care

    We ship with a signed installer and auto-updates, watch crash reports and put out new versions on a regular basis.

03 Technology

Technology That Fits the Need

We are not tied to a single framework. We choose based on target platforms, hardware needs, package size and your team's expertise.

  • 01

    Native .NET: WinUI and WPF

    Built in C# when the target is Windows only; suited to the closest OS integration and a Windows-native interface.

  • 02

    Electron Across Three Platforms

    One web-technology codebase for Windows, macOS and Linux. A mature ecosystem, traded off against larger packages and higher memory use.

  • 03

    Tauri for Lighter Packages

    The interface is written with web technologies; because it uses the OS's own web view, packages are usually smaller.

  • 01.NET
  • 02C#
  • 03WinUI
  • 04WPF
  • 05Electron
  • 06Tauri
  • 07MSIX
  • 08TypeScript
  • 09React
  • 10Node.js
  • 11GitHub
  • 12VS Code

04 Proof

Our Own Desktop Apps

We built both and offer them for free; on Windows, both update themselves.

05 FAQ

Frequently Asked Questions

Questions worth settling before you start a desktop app project.

01

Should we build a desktop app or a web application?

Choose a desktop app if you need constant background operation, offline use, hardware access or deep operating system integration; otherwise a web application is usually the better choice. A web app needs no installation and updates in one place. A desktop app does what the browser does not allow. In discovery we assess your needs against these criteria and recommend both together when that fits.

02

How do you choose between Electron, Tauri and .NET?

Target platforms, depth of integration and package size drive the choice. If the target is Windows only and the app must work closely with the operating system, native .NET (WinUI or WPF) leads. If one codebase across three platforms and a mature ecosystem matter most, Electron is a strong option; if smaller packages and lower memory use come first, Tauri is. We confirm the decision in the prototype phase.

03

What drives the cost of desktop app development?

A few factors drive the cost: how many operating systems you target, how complex the interface is, how deep the hardware and OS integrations go, whether you need offline work and sync, whether a server side or admin panel is required, and distribution work such as code signing, updates and maintenance. After a short discovery call, we share a scoped estimate.

04

How long does it take to build a desktop app?

It depends on scope, so we talk in ranges rather than fixed dates. A tray utility focused on a single job can often reach a first release in a few weeks. A business app with hardware integration, offline sync and several platforms can take a few months. We set the schedule together after discovery and the prototype.

05

Why do code signing and auto-updates matter?

Code signing shows who published the app and that it was not altered on the way. Unsigned installers trigger SmartScreen warnings on Windows and Gatekeeper warnings on macOS, and apps distributed outside the Mac App Store also need notarization to open without a warning. Auto-updates make sure bug and security fixes reach every user. We set up a flow that downloads updates in the background and verifies their signature or hash.

06

Do telemetry and crash reports conflict with user privacy?

Not when they are set up properly. We define up front which data is collected and why, leave out personal data unless it is needed and tell users clearly; where required, we add a consent flow for GDPR and KVKK. Crash reports without personal data are often enough to find bugs. Our own apps, Next Windows and Next Notify, collect no usage data; telemetry is a deliberate decision in every project.
