Building a desktop app begins by selecting an appropriate platform approach: native options for Windows/macOS/Linux, cross-platform frameworks, and how you deploy it. Defining a solid MVP and an early prototype aids in verifying 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 functionality, and integrations (device APIs, peripherals, enterprise authentication) ensures dependable daily operation, while a robust update system and crash reporting streamline ongoing maintenance.
