Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross-platform tools, and the distribution method. A clearly outlined MVP along with an early prototype helps verify workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable everyday use, while a robust update system and crash reporting streamline ongoing maintenance.
