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

As the product evolves, stability, updates, and packaging take center stage. Attentive management of file systems, permissions, offline operation, and integrations (device APIs, peripherals, enterprise authentication) makes the application dependable in everyday use, while an update system and crash reporting ease long-term maintenance.
