Building a desktop app begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform options, and the distribution method. A clearly outlined MVP and an early prototype verify workflows, performance requirements, and the user experience on actual hardware.

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