Linux Desktop Apps

Linux Desktop App Development Services

GTK, Qt, and cross-platform applications that behave correctly on GNOME, KDE, Wayland, and every distribution you need to support.

Linux Applications That Respect the Desktop

Linux users are unusually good at spotting software that was written for another platform and dropped onto theirs. A well-built Linux app uses the system theme, honours the desktop’s shortcuts and portals, works on Wayland, and installs through the channel the user already trusts.

We build native GTK and Qt applications for that audience, and we also ship the pragmatic option (Electron, Tauri, or a JVM build) when a shared codebase is the right commercial call. Either way, you get packages for Flatpak, Snap, AppImage, and native distro repositories, tested on the distributions your users actually run.

  • GTK 4 and Qt 6 applications that follow desktop conventions
  • Wayland-native with X11 fallback for older environments
  • Packaged as Flatpak, Snap, AppImage, .deb, and .rpm
  • Tested across Ubuntu, Debian, Fedora, Arch, and openSUSE

Our Linux Development Services

Desktop software, developer tooling, and embedded interfaces built on Linux.

Native GTK & Qt Applications

Desktop apps built with GTK 4 or Qt 6 that use the system theme, portals, and shortcuts your users already expect.

  • GTK 4 with libadwaita
  • Qt 6 and QML interfaces
  • GNOME and KDE integration

Cross-Platform Linux Builds

Electron, Tauri, Avalonia, and JVM applications with a Linux build that is a first-class release, not an afterthought.

  • Shared codebase with Windows and macOS
  • Correct desktop entries and MIME handling
  • Native system tray and notifications

Developer Tools & Hybrid CLIs

Tooling for technical users: a scriptable command line and a graphical interface over the same well-tested core.

  • Shared core with CLI and GUI front ends
  • Shell completion and man pages
  • Config files that play well with dotfiles

Kiosk, Embedded & Industrial UIs

Single-purpose Linux interfaces for kiosks, control panels, and devices, built to run unattended for months at a time.

  • Fullscreen kiosk and digital signage modes
  • ARM64 and Raspberry Pi builds
  • Watchdogs and unattended recovery

Packaging & Repository Hosting

Every install path covered, with signed repositories and update channels you control rather than rent.

  • Flatpak, Snap, and AppImage builds
  • .deb and .rpm packages with signed repos
  • Flathub and Snap Store publishing

Porting to Linux

Bringing an existing Windows or macOS application to Linux without forking your codebase or your roadmap.

  • Codebase and dependency audit
  • Replacing platform-specific APIs
  • Continuous Linux builds in your CI

What We Get Right on Linux

The differences between an app that runs on Linux and one that belongs there.

Wayland & X11

Wayland-native behaviour for window handling, clipboard, and screen capture, with a working X11 fallback.

System Theming

Light and dark themes, accent colours, and icon sets that follow GNOME and KDE settings instead of overriding them.

HiDPI & Fractional Scaling

Crisp rendering on mixed-DPI multi-monitor setups, including the fractional scaling users actually run.

Sandboxing & Portals

Flatpak and Snap confinement with XDG portals for file access, so permissions stay explicit and minimal.

systemd & Background Services

Correct systemd units, user services, and D-Bus interfaces for anything that needs to keep running.

Reproducible CI Builds

Every package format built and tested in CI on each distribution, so a release is never a manual afternoon.

Distribution

How Your Linux App Gets Installed

Linux users install software four different ways. We support all of them.

Flathub

Flatpak builds published to Flathub, sandboxed with the portals your app genuinely needs.

Snap Store

Snap packages with automatic updates and staged release channels for beta testers.

AppImage

A single portable file that runs anywhere, with no install step and no root required.

Distro Repositories

Signed .deb and .rpm packages in your own apt or dnf repository for managed fleets.

Our Linux Development Process

Targeting the distributions your users run, not just the one on our machines.

1. Discovery & Target Matrix

We agree which distributions, desktop environments, display servers, and architectures are in scope, before a line of code depends on the answer.

2. Toolkit Selection

GTK, Qt, or cross-platform. We weigh how native the app needs to feel against how much of your codebase should be shared, and document the reasoning.

3. Interface Design

Designs that follow the GNOME or KDE human interface guidelines, including keyboard-driven workflows and both light and dark themes.

4. Development

Iterative delivery with nightly builds published to a test channel, so you can install and run the real thing throughout the project.

5. Multi-Distro Testing

Automated CI runs across the target distributions and desktops, plus manual passes on Wayland and X11 sessions and HiDPI setups.

6. Packaging & Release

Flatpak, Snap, AppImage, and native packages built, signed, and published, with update channels and crash reporting in place.

Frequently Asked Questions

What clients ask us most before starting a Linux desktop project.

Which distributions do you support?

We test by default on Ubuntu LTS, Debian stable, Fedora, Arch, and openSUSE, and we can add others to the matrix. In practice, a Flatpak or Snap build covers the long tail of distributions on its own, while native .deb and .rpm packages cover the managed fleets that will not use sandboxed formats.

Should we build natively with GTK or Qt, or use Electron?

If Linux is a primary platform, or your users are developers and open-source-minded, a native GTK or Qt app will be received far better: smaller, faster, and properly themed. If Linux is one of three desktop targets for a business application, Electron or Tauri usually gives you a better return. We will tell you which case you are in.

Do you handle Flathub and Snap Store publishing?

Yes. We prepare the manifests, sandbox permissions, metadata, and screenshots, then take the submission through review. After launch we can keep publishing releases for you, or hand over a documented CI pipeline so your own team can.

Can you port our Windows or Mac application to Linux?

Usually, yes. We start with an audit of the codebase and its dependencies to find what is genuinely platform-bound. Cross-platform frameworks tend to port in weeks; deeply native applications may need a rewritten UI layer over a shared core, and we will give you an honest estimate of which situation you are in before committing.

Will the app work on Wayland?

Yes. We build Wayland-native, since it is now the default session on Ubuntu, Fedora, and most current distributions, and we keep an X11 fallback for older environments. Screen capture, clipboard, and global shortcuts are handled through portals so they work correctly under both.
