Desktop & PC app development cost
A desktop application costs $60,000 to $130,000 for a focused build and $165,000 to $380,000 for a production product across Windows and macOS. What separates desktop from every other platform is that you own distribution: installers, code signing, notarisation, auto-update and version skew are your problem, and they are typically 15–20% of the build rather than an afterthought.

What a desktop app costs depends on your scope
This page sets out what the platform itself demands: 10 device configurations worth testing, self-distribution, and the surfaces you have to build. Put your own scope through the calculator and it returns the figures.
What makes Desktop cost what it does
Three things, and only the first is the one people estimate: building the interface, testing the device matrix, and getting it distributed.
Surface cost
1.12x
0.68x as an additional surface
An additional surface costs well under the first because product logic, API contracts, design and test scenarios are already paid for. Only the platform-specific implementation repeats.

Windows and macOS are separate targets with separate installers, signing regimes, update mechanisms and filesystem conventions. Enterprise Windows adds group policy, locked-down user accounts and antivirus interference.
Distribution
You own it
No store, no review, no commission
Nothing stands between a fix and your users — and nothing handles updates, signing or trust for you either.
Real constraints
- You own updates. There is no store to push through, so auto-update, rollback and version-skew handling are yours to build and are not optional for a product users keep open for months.
- Code signing is mandatory in practice: an unsigned Windows binary triggers SmartScreen and an unsigned macOS app will not open. Certificates, notarisation and hardened runtime are real setup and annual cost.
- Users expect real desktop behaviour: multi-window, menu bars, keyboard shortcuts, drag and drop, offline operation and native file dialogs.
- Enterprise deployment means MSI/MSIX or PKG packaging, silent install and MDM distribution, which is a project in itself.
Genuine strengths
- The right answer for long-session, high-density, keyboard-driven work — trading, design tools, clinical workstations, industrial control, editing.
- Direct filesystem, peripheral and local-hardware access that browsers cannot reach.
- Genuine offline capability, which matters in manufacturing, maritime, clinical and field settings.
- No store gatekeeper and no commission on your own sales.
Choose something else when
- A web app in a browser would do the job — which is most business software, and it saves you the entire distribution and update problem.
- Your users are casual or occasional; asking them to install and update software is a real conversion cost.
What you are actually paying for
Three costs specific to this platform and independent of what the app does. The calculator prices them against your own scope.

Distribution

days — you distribute it yourself
No store gatekeeper — which also means no store distribution, no store billing and no store discovery.
Surfaces

0.68x as an additional surface
A second surface never costs what the first did — the backend, data model, product logic and test scenarios are already paid for.

Desktop cost, answered
Electron, Tauri or native?
Electron is the pragmatic default: you ship one web codebase to Windows, macOS and Linux, and if you already have a web app much of it transfers. The costs are a 80–150MB binary and heavier memory use. Tauri produces far smaller, faster binaries using the system webview and is a strong choice for new work, at the price of a smaller talent pool and Rust in your stack. Go fully native — Swift or .NET — when performance, deep OS integration or platform-idiomatic feel is the product, as in professional creative and clinical tools.
What does code signing and distribution actually cost?
A Windows OV certificate is roughly $200–$400 a year and an EV certificate $300–$700; without one, SmartScreen warns every user until you accumulate reputation. Apple requires a $99/year Developer Program membership plus notarisation, and an unsigned app simply will not launch. On top of the fees, budget 40–70 hours to build signing into CI, implement auto-update with rollback, and produce enterprise installers. This is the line item desktop estimates most often omit.
Should we build desktop or just a web app?
Build web unless you have a specific reason not to. The reasons that genuinely justify desktop are: you need real offline operation, you need local filesystem or peripheral access a browser cannot reach, your users live in the app for hours and need native performance and keyboard depth, or your customers require on-premises software for policy reasons. If none of those apply, a web app removes installation, updates, signing and the entire support burden that comes with software on someone else’s machine.
