Creating 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 outlined MVP and an initial prototype help validate workflows, performance requirements, and the overall user experience on real devices.

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