Building a desktop app begins by selecting an appropriate platform approach: native across Windows/macOS/Linux, cross‑platform tools, and how you’ll distribute it. A clearly defined MVP and an early prototype help verify workflows, performance requirements, and the overall user experience on actual 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 dependable daily operation, while an update system and crash reporting ease ongoing maintenance.
