Building a desktop application begins by selecting an appropriate platform approach: native (Windows/macOS/Linux), cross‑platform frameworks, and how you’ll distribute it. A clearly defined MVP plus an early prototype helps confirm workflows, performance requirements, and the overall user experience on real devices.

As the product evolves, stability, updates, and packaging take center stage. Thoughtful management of file systems, permissions, offline capabilities, and integrations (device APIs, peripherals, enterprise authentication) ensures reliability in everyday use, while an update system and crash analytics ease ongoing maintenance.
