Desktop App Development Company

Most businesses default to web apps for everything. But when your team works offline in the field, needs GPU access for processing-heavy tasks, handles sensitive data that must stay on-device, or runs a workflow that requires deep OS integration, a web app won't cut it.
RaftLabs builds native desktop applications for Windows, macOS, and cross-platform using Electron and Tauri. Field tools, internal ops software, creative tools, and enterprise applications that run reliably without a browser.

When a web app isn't the right tool

A web app requires a browser, a server, and a working network connection. That's fine for most workflows. It's not fine when your team is inspecting equipment in a basement with no signal, when your data cannot leave the device under any circumstances, when you need to talk directly to a USB peripheral or a local printer, or when your processing task would take 40 seconds in the cloud but 400 milliseconds on the user's own hardware.

Desktop apps exist for exactly these situations. Not as a fallback, but as the right architectural decision for the constraints you're working with.

Capabilities

What we build

Windows app development

Custom Windows desktop applications built with WinUI 3, WPF, or Electron depending on your requirements. Native Win32 API access covers file system operations, system tray presence, background services, and hardware peripherals over USB, serial, or HID. WinUI 3 for modern Windows 11 apps, WPF for older Windows targets or existing codebases. Packaging via MSIX or signed installers, auto-update via Squirrel, and enterprise deployment through Group Policy or Microsoft Intune.

macOS app development

Native macOS applications built with SwiftUI or AppKit for the tightest possible platform integration. Native conventions throughout: menu bar presence, Spotlight, drag-and-drop, and the system typography that makes an app feel like macOS rather than a web app in a window. Keychain integration for secure credential storage, sandboxing and notarisation so Gatekeeper passes without prompting users, and auto-update via Sparkle for apps distributed outside the App Store.

Cross-platform Electron and Tauri apps

Cross-platform desktop applications built with Electron: one JavaScript or TypeScript codebase shipping to Windows, macOS, and Linux, the right choice for tools that are already web-shaped. Context isolation and a typed IPC bridge keep OS-level operations out of the renderer, with auto-update via electron-updater. Tauri is the lighter alternative: the OS's native webview instead of bundled Chromium cuts installers from 80-150MB to 5-10MB, with a Rust backend for lower memory use and faster startup.

Offline-first desktop apps

Desktop applications designed from the ground up for environments where connectivity is intermittent, slow, or absent. The local data layer comes first: SQLite stores the working dataset on the user's machine, so reads and writes never depend on the network. Sync architecture is scoped to your conflict scenarios, from last-write-wins to CRDT-based sync that preserves simultaneous offline edits. A background sync service batches changes when connectivity returns, and a status indicator shows users whether their edits have reached the server.

OS integration and system tray apps

Desktop applications that live outside the browser window and integrate at the OS level: system tray apps that run in the background, surface native notifications, and expose key actions from the taskbar or menu bar. Global keyboard shortcuts work whether the window is focused or not. IPC bridges connect to local hardware: serial ports for barcode scanners and label printers, USB HID for card readers, and local network discovery for LAN-connected devices. Startup-on-login is configured so the app is ready before the user opens it.

Desktop app modernisation

Migration of legacy desktop software to modern frameworks without rewriting core business logic from scratch. Common cases: a VB6 or Delphi app nobody can maintain, a WinForms tool that needs a modern UI, or an Access database that has outgrown the spreadsheet. A discovery audit identifies what to port, what to rebuild, and what to cut. We deliver working increments rather than a big-bang rewrite, and data migration to the new schema is included in scope.

How we work

From scope to shipped

Every project follows the same four phases. Scope is locked and price is fixed before development starts.

  1. Week 1
    01

    Discovery and scope

    We map the problem, the user, and the workflow. We define the local data model, OS integration requirements, and offline sync strategy during this phase. You leave week 1 with a written scope document and a fixed-price quote. No development starts without your sign-off.

  2. Weeks 2-3
    02

    Design and architecture

    Wireframes before production code. Data model decisions made here cost ten times less than the same decisions made in week 8. Platform target, framework choice (native vs Electron vs Tauri), and offline sync approach are locked before the build starts.

  3. Weeks 4-12
    03

    Build, integrate, and QA

    Working software with a real installer by the end of sprint one. Bi-weekly demos. QA runs in parallel with every sprint, including offline mode testing, sync conflict scenarios, and OS integration edge cases.

  4. Weeks 12+
    04

    Launch and post-launch support

    Production release with code-signed installers and auto-update configured on launch day. 8 weeks of post-launch support included in every project.

Why us

Why teams choose RaftLabs

  1. Senior engineers build what they scope

    The engineers who assess your problem also build the solution. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.

  2. Fixed price before development starts

    We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.

  3. 9 years and 100+ products shipped

    Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record across desktop, mobile, SaaS, and enterprise platforms in healthcare, fintech, logistics, and hospitality.

  4. Compliance built in from the start

    GDPR, HIPAA, SOC 2 compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped HIPAA-compliant on-device systems for US healthcare clients and GDPR-compliant products for European markets.

Frequently asked questions

A desktop app makes sense when one or more of these conditions apply. Your users need the software to work without an internet connection, such as field inspectors, warehouse teams, or anyone operating in low-connectivity environments. Your workflow requires direct access to the local file system, USB devices, serial ports, printers, or cameras in ways a browser cannot expose cleanly. You're handling sensitive data that must stay on the device and never transit a server. Your processing tasks are CPU or GPU intensive enough that network latency to a cloud server would make the experience unusable. Or your users need OS-level features like system tray notifications, background services, or global keyboard shortcuts. If none of those apply, a web app is usually the right choice and we'll tell you that in the scoping call.

Electron (which packages a Chromium browser and Node.js into a desktop installer) is the right choice when you need to ship on Windows and macOS from a single codebase, your team already works in JavaScript or TypeScript, and your app's workload is not graphics-intensive. Electron runs well for tools, dashboards, data entry, and internal ops software. Tauri is a third option worth knowing: it uses the OS's native webview instead of bundling Chromium, producing a much smaller installer (typically 5-10MB vs Electron's 80-150MB) while still letting you build the UI in web technologies. The backend logic runs in Rust rather than Node.js, which gives Tauri apps a lower memory footprint and faster startup. Native development (Swift or SwiftUI for macOS, C# with WinUI or WPF for Windows) is the right choice when you need the tightest OS integration, the best performance on hardware-intensive tasks, or deep access to platform-specific APIs. We scope the right approach during discovery based on your use case, device targets, and team constraints, not a blanket preference.

Yes, and that's one of the main reasons to build a desktop app rather than a web app. We design the local data layer first. Data lives in a local database (SQLite is the most common choice for desktop apps) on the user's machine. The app reads and writes locally with no network dependency. When connectivity is available, a sync layer pushes local changes to the cloud backend and pulls remote updates down. We design the conflict resolution logic during discovery so that simultaneous offline edits from multiple users don't produce corrupted records when they sync. The offline-first architecture is not an add-on, it shapes the data model from the start.

A focused desktop app, core workflow, local data storage, and cloud sync for one platform, typically runs $25,000-$60,000. Cross-platform builds (Windows and macOS from a single Electron codebase) add roughly 20-30% compared to a single-platform build. Apps with complex OS integrations, hardware peripheral support, or enterprise security requirements run higher. We scope every project before pricing it and give you a fixed cost, not a time-and-materials estimate.

Most desktop apps ship in 10-16 weeks from project start to a production installer. The range depends on scope, the complexity of the offline sync layer, and the number of OS integrations required. We start with a discovery phase (1-2 weeks) to define the data model and architecture before writing application code. Weekly sprints with working builds mean you're reviewing real software from week two, not waiting until the end for a demo.

Yes. We sign NDAs before any technical discussion begins. For desktop apps handling sensitive on-device data, proprietary business logic, or regulated information (HIPAA, GDPR), we treat confidentiality as a baseline requirement, not an optional add-on. Source code ownership transfers to you on final delivery.
