Cross-Platform Desktop App Development for Windows, macOS & Linux
Ship one desktop application to every operating system your customers use. We build modern, secure and lightweight desktop apps with Electron, Tauri, Qt, Avalonia, Flutter and .NET MAUI.
Write once, run on every desktop
VS Code, Slack, Figma, Discord and many other popular tools are cross-platform desktop apps. With the right framework you get one codebase, one team and simultaneous releases on Windows, macOS and Linux, while still accessing the file system, system tray, notifications and local hardware.
We help you pick the right framework. Tauri gives tiny, secure apps with a Rust core. Electron offers the richest web ecosystem. Qt gives native C++ performance. Avalonia and .NET MAUI suit C# teams. We then build, sign, package and auto-update your app on every platform.
What you get
- Single codebase for 3 operating systems
- Modern UI with React, Vue or native widgets
- File system, tray & OS notifications
- Offline mode with local database
- Secure IPC and sandboxing
- Auto-update for every platform
- Code signing & notarisation
- Store distribution (MS Store, Mac App Store, Snap)
Frameworks we build with
The right tool for your performance, size and team requirements.
Electron
Feature-rich apps using web technologies and Node.js; ideal for turning your web app into a desktop product.
Tauri
Rust-powered apps as small as a few MB with strong security and low memory use.
Qt (C++ / QML)
High-performance native apps for engineering, 3D, embedded and industrial software.
Avalonia & .NET MAUI
C# / XAML apps that share code with your existing .NET libraries and backends.
Flutter Desktop
Share UI and logic with your Flutter mobile app across desktop platforms.
Migration & Consolidation
Merge separate Windows and Mac apps, or move WinForms / WPF apps to cross-platform.

Cross-platform desktop questions
Electron or Tauri?
Electron has the largest ecosystem and is very mature. Tauri produces much smaller, lighter apps with a Rust backend. For most new projects where size and security matter we recommend Tauri.
Can my existing web app become a desktop app?
Yes. We can wrap your React, Angular or Vue app in Electron or Tauri and add desktop features like offline mode, file access and notifications.
Will it look native on each OS?
We follow each platform's conventions for menus, shortcuts and window behaviour. Qt and Avalonia can closely match native look and feel.
How are updates delivered?
We set up automatic, signed updates so users always get the latest version without reinstalling.
