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

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