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

As the product evolves, stability, updates, and packaging become essential. Careful management of file systems, permissions, offline functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures reliable everyday use, while an update mechanism and crash reporting ease long-term maintenance.
