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.
