Building a desktop app begins by selecting a suitable platform approach: native options (Windows/macOS/Linux), cross‑platform solutions, and the way you distribute the software. A clear MVP and an initial prototype aid in confirming 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 use, while an update system and crash reporting ease ongoing maintenance.
