Expert Verdict

MachineMetrics

MachineMetrics is the right choice for enterprise discrete manufacturers needing deep CNC integration, vibration monitoring, and developer-extensible APIs. Not recommended for cost-sensitive SMBs as a first monitoring tool.

💰 Pricing: Volume-based SaaS subscription · Price not publicly disclosed · More machines = lower per-machine rate · All plans include unlimited support and onboarding · Custom quote required

Plex (Rockwell)

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.

💰 Pricing: Custom enterprise quote · Annual subscription · ERP module pricing varies
⚖️
Bottom Line
MachineMetrics wins 3 of 12 categories, a clear edge in overall intelligence. Plex (Rockwell) is the stronger choice if cloud mes + erp is your primary requirement.
