Why we added Linux support to Crosspay

In the world of commercial software development, Linux is often the "Day 2" platform. It is the port you promise on your roadmap but never quite get around to shipping. When it comes to monetization, the situation is even bleaker. The prevailing wisdom is simple: "Linux users don't pay for software."

We believe this wisdom is outdated, lazy, and wrong.

Today, we are sharing why we spent six months building first-class Linux support into Crosspay, and why we believe it is a critical competitive advantage for modern cross-platform apps.

1. The Steam Deck Effect

The Linux desktop market is no longer just sysadmins and kernel hackers. The massive success of the Steam Deck has normalized Linux (specifically Arch-based distributions) as a consumer gaming platform.

This has created a ripple effect. Users are growing accustomed to paying for premium experiences on Linux. Whether you are building a game in Godot or a utility tool in Flutter, there is now a paying audience on this OS that is hungry for native experiences—and they are currently being ignored.

2. The Rise of "Write Once" Frameworks

The maturation of Flutter and Electron has made shipping a Linux binary trivial. A developer can now spin up a Linux build of their iPad app in minutes.

But the business logic hasn't kept up. You can compile the app, but you can't bill the user. You are forced to redirect them to a web portal to enter a credit card, breaking the immersion and introducing friction. We wanted to close that gap. We wanted the purchase flow on Ubuntu to feel as native as it does on iOS.

3. Solving the Fragmentation Nightmare

"Linux" is not one platform; it is a dozen. Are you distributing via Snapcraft? Flatpak? AppImage? Or a .deb file?

Each distribution method implies a different sandboxing model and a different expectation for payments.

• Canonical has its own Snap Store APIs.
• Flatpak is often decentralized.
• Direct downloads need a Stripe/PayPal integration.

Crosspay abstracts this chaos. We built a standardized adapter layer that detects the distribution environment. If you are running in a Snap, we can bridge to the Snap Store. If you are running standalone, we fallback to a secure, embedded Stripe view. To your code, it all looks like Crosspay.purchase().

4. The Enterprise Factor

Many of our customers are building developer tools, scientific software, and server management utilities. Their power users live in the terminal.

Forcing these high-value enterprise customers to switch devices just to manage a subscription is a bad user experience. By supporting Linux, we allow our customers to monetize their users where they work.

The Code

The beauty of our implementation is that it requires zero Linux-specific code in your app.

// This code runs on Ubuntu 24.04, SteamOS, and Fedora
const entitlements = await Crosspay.getEntitlements();

if (entitlements.includes('pro_tier')) {
  showTerminalThemeEditor();
} else {
  // Triggers the native/embedded purchase flow appropriate for the distro
  await Crosspay.purchase('pro_tier');
}
            

Conclusion

We added Linux support not because it has the largest market share, but because "Cross-Platform" shouldn't come with an asterisk. If your code runs there, your business should run there too.
