Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross‑platform frameworks, and the distribution method. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real hardware.

As the product evolves, stability, updates, and packaging take center stage. Careful management of file systems, permissions, offline support, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains reliable in daily use, while an update mechanism and crash reporting simplify long-term maintenance.
