Building a desktop app starts with choosing the right platform approach: native on Windows/macOS/Linux, cross-platform frameworks, and the delivery model. A clearly defined MVP and an early prototype help validate workflows, performance requirements, and the overall UX on real machines.

As the product evolves, reliability, updates, and packaging take center stage. Thoughtful handling of file systems, permissions, offline mode, and integrations (device APIs, peripherals, enterprise authentication) ensures the app remains dependable in daily use, while an update mechanism and crash reporting simplify long-term support.
