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

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 daily operation, while a built-in update system and crash reporting streamline ongoing maintenance.
