Plex is the right choice for mid-market discrete manufacturers wanting machine monitoring as part of a broader cloud MES/ERP investment, particularly in automotive supply chain environments where Plex has deep vertical expertise.
IoTFlows is a strong choice for mid-market and enterprise manufacturers wanting a single multi-sensor IIoT platform with no-code dashboards, unlimited users, and open APIs. The subscription-only hardware model and opaque higher-tier pricing are the primary trade-offs to evaluate.
