Building a desktop app begins by selecting an appropriate platform strategy: native across Windows/macOS/Linux, cross-platform frameworks, and the distribution approach. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on actual devices.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise authentication) ensures the application remains dependable in everyday use, while an update system and crash analytics ease ongoing maintenance.
