Building a desktop app begins by selecting an appropriate platform approach—native across Windows/macOS/Linux, cross-platform options, and the distribution 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 evolves, reliability, updates, and packaging take center stage. Careful management of file systems, permissions, offline support, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily operation, while an update system and crash reporting ease long-term maintenance.
