NI LabVIEW (Professional & Community)

The 'Gold Standard' for graphical dataflow programming. In 2026, it features the 'Nigel AI Advisor' for VI design assistance and a unified debug window. While its hardware integration with NI and third-party instruments is unrivaled, the high cost of its professional subscription and the complexity of managing runtime engines drive many toward Python-based open-source stacks.
