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

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures daily reliability, while an update system and crash reporting ease long-term maintenance.
