Building a desktop app begins by selecting an appropriate platform approach: native targets for Windows/macOS/Linux, cross‑platform frameworks, and the chosen distribution method. Defining a solid MVP and an initial prototype aids in verifying workflows, performance requirements, and the overall user experience on actual hardware.

As the product evolves, reliability, update management, and packaging take center stage. Managing file systems, permissions, offline capability, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily operation, while an update system and crash reporting streamline ongoing maintenance.
