How Much Does It Cost to Make a Desktop App?
From $0 to $250,000 - what desktop apps actually cost in 2026 across the four realistic paths, including the hidden line items nobody quotes up front.
Anywhere from $0 to $250,000+, which is an honest answer and a useless one. Here's the real breakdown by path, assuming you already have a product (or a web app) and want it on desktops.
Path 1: Wrap your existing web app with a platform - $240-600/year
If your product already runs in a browser, platforms like Deskifier turn it into signed Mac, Windows and Linux apps for a subscription (ours starts at $20/month per platform product). That price includes the expensive invisible parts: code signing certificates, Apple notarization, update hosting and store packaging. Time cost: an afternoon.
Path 2: Build the wrapper yourself - $10,000-40,000 in engineering time
The software is free (Electron, Tauri); the cost is labor. A realistic first-time budget: 2-6 engineer-weeks for the shell, signing setup, installers and auto-updates, at typical loaded rates that's five figures - then a permanent tax of runtime upgrades roughly every 8 weeks. Plus hard costs: Apple Developer Program ($99/yr), a Windows code-signing route (roughly $100-400/yr via cloud signing), and CI runners for three platforms.
Path 3: A custom native app from scratch - $50,000-250,000+
Native Swift/C++/C# apps, or a full Electron product with its own desktop codebase, built by an agency or in-house team. Justified when the desktop IS the product (think audio tools, IDEs) - not for putting an existing product on desktops.
The line items people forget
- Code signing - without it, macOS Gatekeeper and Windows SmartScreen warn users away from your installer. Non-optional for real distribution.
- Auto-update infrastructure - version two is pointless if version one can't receive it.
- App store fees - Apple $99/yr, Microsoft ~$19 one-time for individuals.
- The maintenance cadence - browser engines ship security patches constantly; whoever owns your wrapper owns that treadmill.
The one-line summary
Have a web app already? Hundreds per year through a platform, or tens of thousands in engineering time to own the stack. Building a desktop-native product from zero? Budget like it's a second product, because it is.
