Building a desktop application begins by selecting an appropriate platform approach: native for Windows/macOS/Linux, cross-platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help confirm workflows, performance requirements, and the overall user experience on real hardware.

As the product evolves, reliability, updates, and packaging take center stage. Diligent management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily operation, while an update system and crash reporting streamline long-term maintenance.
