When the browser is not enough

Desktop applications still win where web apps cannot follow: heavy local processing, direct access to USB and serial hardware, large local files, strict offline operation, and deep OS integration. We build software that uses the machine properly instead of fighting browser sandboxes and upload limits.

Native or cross-platform β€” chosen on merit

Cross-platform frameworks like Electron and Flutter ship one codebase to every OS quickly. Native stacks (.NET/WPF, Qt/C++, Swift) deliver the lowest memory footprint and tightest hardware control. We recommend based on your performance, hardware, and budget needs β€” not on what we prefer to write.

Installers, updates, and signing done right

Most desktop projects stumble after the build: code signing, silent auto-update, versioning, rollback, and enterprise deployment via MSI or MDM. We handle the full release pipeline so your users get seamless updates and IT teams can deploy at scale without manual reinstalls.

When your business needs a desktop application

πŸ”Œ

You need to talk to hardware

USB, serial, scanners, medical devices, POS peripherals, or industrial equipment that browsers cannot access reliably.

πŸ“΄

It must work fully offline

Factory floors, ships, clinics, and remote sites where connectivity is unreliable or prohibited entirely.

βš™οΈ

Heavy local processing

Video, CAD, large datasets, or compute-intensive work that would be slow or costly in a browser.

πŸ—„οΈ

Large local file handling

Applications that read, write, and organise big files on disk without upload limits or round trips.

πŸ”

Data must stay on the machine

Compliance or policy requires that sensitive data never leaves the local device or internal network.

πŸ–±οΈ

Deep OS integration

System tray, global shortcuts, background services, printing, and native OS notifications.

Desktop framework comparison: Electron vs .NET/WPF vs Qt/C++ vs Flutter

Choosing the framework is the highest-impact decision in a desktop project. Here is how the main options compare, and where each genuinely fits best.

FrameworkBest forStrengthsTrade-offs
Electron (JS/TS)Web teams shipping to all three OS fastOne codebase, huge ecosystem, reuses web skills and UILarger install size and higher memory use
.NET / WPF (C#)Windows-first business and enterprise softwareExcellent Windows performance, mature tooling, strong enterprise integrationPrimarily Windows; cross-platform needs MAUI/Avalonia
Qt / C++Hardware control and performance-critical appsNative speed, low footprint, best-in-class device and USB accessHigher development cost and specialist skill set
Flutter DesktopTeams already building Flutter mobile appsShared codebase with mobile, highly custom UI, good performanceYounger desktop ecosystem, fewer OS-specific integrations

We are not tied to any one framework. After a short discovery call we recommend the option that fits your hardware, performance, timeline, and budget β€” and explain the reasoning.

How much does desktop application development cost?

Desktop cost is driven mainly by platform count, hardware integration, and offline complexity. Typical ranges from our engagements are below.

Project typeTypical costTimeline
Simple single-platform utility or tool$10,000 – $28,0005 – 10 weeks
Business desktop app (one OS)$28,000 – $75,0002 – 5 months
Cross-platform app (Windows + macOS)$45,000 – $120,0003 – 6 months
Hardware/device-integrated application$60,000 – $180,0004 – 9 months
Legacy desktop modernizationFrom $20,0006 – 16 weeks

Ranges are indicative. Code signing certificates and any third-party hardware SDK licences are additional and billed at cost.

Flexible engagement & pricing models

Every business is different, so we offer several ways to work together. Start with a free consultation and we will recommend the model that best fits your scope, timeline, and budget.

πŸ“

Fixed-scope project

Best for well-defined builds. We agree scope, timeline, and a fixed price up front so you know exactly what you get and what it costs.

πŸ‘₯

Dedicated team

A cross-functional squad β€” engineers, designers, QA, and a project lead β€” that works as an extension of your business, month to month.

πŸ”§

Staff augmentation

Add senior developers or AI specialists to your existing team to fill skill gaps and accelerate delivery without long hiring cycles.

πŸ”

Support & retainer

Ongoing maintenance, optimisation, and new-feature development on a predictable monthly retainer after launch.

Our delivery process

1

Discovery & strategy

We map your goals, users, and workflows, then define scope, architecture, and a clear roadmap with fixed milestones and transparent pricing β€” no surprises, no scope creep.

2

UX design & prototype

Wireframes and interactive prototypes validate the experience and de-risk the build before a line of production code is written, saving you time and budget.

3

Agile development & QA

We build in two-week sprints with continuous integration, automated testing, and live demos, so you see working software early and steer it as it grows.

4

Launch, support & scale

We deploy to the cloud with monitoring, security hardening, and CI/CD, then iterate with analytics-driven improvements and ongoing support as you scale.

Frequently asked questions

What platforms do you build desktop applications for?

Windows, macOS, and Linux β€” either natively per platform or from a single cross-platform codebase using Electron or Flutter Desktop, depending on your performance and budget needs.

Electron or native β€” which should I choose?

Electron is ideal when you want all three platforms quickly and your team knows web technologies. Native (.NET/WPF, Qt/C++, Swift) is better for hardware control, low memory use, and maximum performance. We advise based on your specific requirements.

Can the desktop app communicate with hardware or USB devices?

Yes. We build applications that talk to USB, serial, Bluetooth, scanners, printers, and industrial or medical devices β€” usually with Qt/C++ or .NET where low-level access matters.

Will the application work completely offline?

Yes. Desktop apps can run fully offline with a local database, then optionally synchronise with a server when a connection is available.

Do you handle installers, code signing, and auto-updates?

Yes. We deliver signed installers (MSI, DMG, and Linux packages), silent auto-update, versioning and rollback, and enterprise deployment support.

Can you modernise our old Windows desktop application?

Yes. We migrate legacy WinForms, VB6, and Delphi applications to modern .NET or cross-platform stacks incrementally, preserving business logic while improving performance and supportability.

How much does desktop app development cost?

Simple utilities typically start around $10,000, business desktop apps run roughly $28,000–$75,000, and hardware-integrated software costs more. You get a fixed-scope quote after a free consultation.
