desktop application development

Cross-platform desktop applications built with Electron and Tauri, for the situations where a browser tab falls short. Native OS access, offline operation, local data storage, system tray integration, file system access, hardware communication. Web applications can't do these things reliably. When your product needs any of them, you need a desktop app.

The cross-platform framework market is projected to grow from $15.67 billion in 2025 to $42.60 billion by 2034 at an 11.75% CAGR (Market Research Future, 2025). Desktop specifically is expected to hit $6.0 billion by 2034, mostly because enterprises keep running into the same wall: they need offline capability and OS-level integrations that browsers won't give them (Persistence Market Research, 2025).

when a desktop app is the right answer#

what web apps can't do, and why it still matters#

Modern web browsers have gotten considerably more capable. But several things remain out of reach: persistent background processes that run without a browser window, unrestricted local file system access, native OS notifications and system tray integration, local data storage with real database performance, hardware communication (Bluetooth LE, serial ports, USB HID), and operation in environments with no internet connection.

If your product needs any one of these, a desktop application isn't a preference. It's a technical requirement. The question is which desktop framework fits the project's constraints.

the five signals that point toward a native desktop build#

Consider a desktop application when:

1. The product must work offline. Remote field tools, local data editors, and industrial control software can't depend on network availability.
2. The product needs to talk to local hardware. Serial ports, Bluetooth peripherals, USB HID devices, or system-level audio need OS-level access.
3. The product is a persistent background process. System monitors, local AI agents, scheduled automation tools, developer utilities that live in the tray. Not a browser tab.
4. Performance or memory constraints make a browser runtime impractical. Some tools need predictable memory footprint and startup times that a web app can't guarantee.
5. Security or compliance requirements prevent data from leaving the machine. On-premise and air-gapped environments where nothing should travel over the network.

desktop companions: extending a web platform without rebuilding it#

Not every desktop project starts from scratch. A common pattern is an existing web SaaS product that needs a desktop companion for specific functions: local file sync, clipboard access, native notifications, offline data capture. The companion shares the web product's authentication, data model, and backend. It adds the OS-level surface that the web app can't cover.

We've built a number of these. The architectural question is always the same: what does the desktop layer need to do that the web layer can't? Everything else stays in the browser.

Electron vs. Tauri: choosing the right framework#

Electron, established, JS-native, heavier#

Electron bundles Chromium and Node.js with your application. Every Electron app ships its own browser engine, which is why binaries are large (typically 80-120 MB) and idle at 200-300 MB RAM. What you get in return is broad ecosystem compatibility: any npm package, any frontend framework, any Node.js module works out of the box.

Electron is the right choice when the team has deep JavaScript/TypeScript experience, the application depends heavily on the web ecosystem, and binary size isn't a constraint. It still powers roughly 60% of surveyed cross-platform desktop applications as of 2025 (Stack Overflow Developer Survey, 2024). The ecosystem maturity reflects that.

Tauri, lightweight, Rust-backed, security-first#

Tauri uses the OS's native webview (WebKit on macOS, WebView2 on Windows, WebKitGTK on Linux) instead of bundling Chromium. The application logic runs in Rust. Binaries come out at 2.5-3 MB, idle RAM sits around 30-40 MB, and startup is noticeably faster. The attack surface is also much smaller.

Tauri 2.0, released October 2024, added stable iOS and Android support. A single Tauri codebase can now target Windows, macOS, Linux, Android, and iOS. Adoption grew 35% year-over-year in 2025 per GitHub metrics. For new projects where binary size or mobile extension matters, Tauri is increasingly the default.

The catch: Tauri requires Rust for the backend process. If your team needs to maintain that layer after handoff, Rust fluency is a real consideration. We assess this per project.

how we decide which framework fits your project#

Four questions determine the recommendation:

1. What is the target binary size and memory budget? If the answer is "as small as possible," Tauri wins.
2. Does the application need to target mobile too? Tauri 2.0 supports mobile natively.
3. Can the team maintaining it after launch write Rust? If not, Electron's JS/TS surface is lower friction for ongoing development.
4. What native OS APIs does the application need? Both frameworks expose OS APIs, but the binding patterns differ. We evaluate this per feature list.

We document the framework selection reasoning in the architecture specification so the client and any future maintainer understands why the choice was made.

what we build#

cross-platform desktop applications (Windows, macOS, Linux)#

Applications that run on all three major desktop operating systems from a single codebase. UI testing covers platform-specific rendering differences. System fonts, native controls, window chrome, keyboard shortcut conventions: these vary more than people expect between operating systems, and users notice when they're off.

desktop companions for web platforms and SaaS products#

File system bridge tools, local sync agents, clipboard managers, native notification systems, offline data capture. These are desktop extensions for existing web products, built to share the web product's auth and data model without requiring a full rebuild.

offline-capable business tools with local data sync#

Applications that work fully without a network connection and sync to a backend when connectivity returns. Local SQLite databases with conflict resolution logic, background sync queues, and optimistic UI updates. When the connection drops, the app keeps working. Pending changes push automatically once the network is back.

AI-integrated desktop agents and productivity tools#

Local inference runners, LLM-powered productivity tools, context-aware assistants that sit in the system tray and respond to OS events. Building AI into desktop apps means making decisions about local vs. remote inference, what context to capture (clipboard, screen, active window), and how to wire the system integration. This is genuinely different from web-based AI work in ways that matter. We've built in this space; see our agentic AI services for more on how we approach it.

how we build it#

discovery: scoping the OS-level requirements#

Discovery for a desktop project focuses on what the operating system needs to provide. We map every capability the application requires, from file system access to hardware ports to background process behavior, and verify that the proposed framework supports each one before writing any code.

We also scope distribution at this stage: direct download, auto-update infrastructure, OS code signing and notarization (required for macOS and Windows Defender compliance), and whether the application will go through an app store (macOS App Sandbox requirements apply if so).

framework selection and architecture#

These happen together. The choice of Electron vs. Tauri affects how the application is structured: how the frontend talks to the native process, how OS APIs are called, how the update system is wired. We produce a written architecture specification covering these decisions before development begins.

build, test, and cross-platform verification#

Development with continuous cross-platform builds. macOS, Windows, and Linux builds come from the same CI pipeline on every push, not assembled at the end. Platform-specific behavior is tested on each target OS: keyboard shortcuts, window management, font rendering, native menu bars, any hardware integration.

For Tauri applications, the Rust backend is tested independently before integration with the frontend. Electron applications use a similar separation between the main process and renderer process to keep testing surfaces clean.

distribution, signing, and update delivery#

macOS code signing and notarization via Apple's Developer ID infrastructure. Windows code signing via a trusted certificate authority (required to prevent SmartScreen warnings on download). Linux distribution via AppImage, .deb, or Snap depending on the target environment.

Auto-update infrastructure is built in from launch: Tauri's built-in updater or Electron's electron-updater module, connected to a release delivery endpoint. Skip auto-update and security debt piles up fast.

pricing and engagement#

project scope and cost range#

Cross-platform desktop applications built with Electron or Tauri typically range from $8,000 for simple single-purpose utilities to $40,000 for full-featured applications with complex OS integration, offline sync, and cross-platform QA.

These ranges assume the application's web or API layer already exists. If backend infrastructure is part of the scope, see web and SaaS development for pricing on that layer.

how this fits alongside a web or AI build#

Desktop applications almost always live inside a larger product. When the desktop app is part of a broader engagement, alongside a web platform, a workflow automation system, or an AI agent deployment, we scope it as a component of the whole rather than a standalone build. This matters for data sync contracts, authentication sharing, and the integration surface between the desktop layer and everything else.

For teams building AI-powered desktop tools, our agentic AI services and browser extension development work are adjacent. Similar distribution challenges, similar OS integration requirements.

frequently asked questions#

When should I build a desktop app instead of a web app?

Build a desktop app when your product requires persistent background processes, local hardware access (Bluetooth, serial, USB), unrestricted file system interaction, offline operation without any network connection, or a security posture where data can't leave the local machine. If none of those apply, a web app is almost certainly the better call. Faster to ship, cheaper to run.

What is the difference between Electron and Tauri for desktop apps?

Electron bundles its own Chromium browser engine and Node.js. That means large binaries (80-120 MB) and high idle memory (200-300 MB), but you get maximum compatibility with the npm ecosystem. Tauri uses the OS's native webview and Rust for the backend process. Binaries are tiny (2.5-3 MB), idle memory is low (30-40 MB), but you need someone who knows Rust. We recommend based on your specific constraints: target binary size, cross-platform requirements, team's technical background, and the OS APIs the application needs.

How much does it cost to build a cross-platform desktop application?

Simple utilities run $8,000-$18,000. Mid-complexity applications with offline sync or hardware integration run $18,000-$35,000. Full-featured platforms with background processes, AI integration, and auto-update distribution pipelines run $35,000-$60,000+. Wide range because the complexity varies enormously.

Can a desktop app work offline without an internet connection?

Yes. Both Electron and Tauri support full offline operation. Local data storage uses SQLite (via better-sqlite3 in Electron, rusqlite in Tauri) or IndexedDB for the renderer process. Sync logic handles offline queues and conflict resolution. The application keeps working while disconnected, and pending changes push automatically when the connection comes back.

What tools and frameworks are used to build desktop apps in 2026?

Electron (Chromium + Node.js, JavaScript/TypeScript) and Tauri (native webview + Rust) are the two leading cross-platform desktop frameworks. Both use web technologies for the UI layer: React, Vue, or plain HTML/CSS/JS. Native development (Swift for macOS, WPF/WinUI for Windows) still makes sense when you're targeting a single platform and need the tightest possible OS integration, but cross-platform frameworks handle most desktop application needs in 2026.
