The short version

  • Each has a real cost: Kepware Server the base server is the small part of the bill; driver suites are priced by protocol family, and a mixed-vendor plant buys several, which is how a connectivity layer alone reaches tens of thousands of dollars.; MachineMetrics no specific pricing published; vendor uses volume-based subscription model requiring sales contact

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kepware Server

  • The base server is the small part of the bill; driver suites are priced by protocol family, and a mixed-vendor plant buys several, which is how a connectivity layer alone reaches tens of thousands of dollars.
  • KEPServerEX to Kepware Server 7 is a migration rather than an in-place upgrade, and driver entitlements do not always transfer cleanly, so budget for revalidating every channel.
  • The full driver portfolio is Windows-only; the Linux product, Kepware Edge, supports a subset of drivers and is subscription-licensed by tag count, so an edge-first architecture cannot simply reuse the Windows configuration.
  • Three names have been in circulation for the same lineage, and quotes, forum answers and integrator experience still mix KEPServerEX, ThingWorx Kepware Server and Kepware Server, which produces mismatched proposals.
  • It is a translation layer with no storage, contextualisation or visualisation of its own, so it is always an addition to a historian or platform purchase rather than a substitute for one.

MachineMetrics

  • No specific pricing published; vendor uses volume-based subscription model requiring sales contact
  • Costs scale with number of connected machines; exact rates not disclosed publicly
  • Customers must book demo or request quote to receive pricing

Answered from the vendors’ own pages

Kepware Server: Is KEPServerEX discontinued?

The name is. KEPServerEX and ThingWorx Kepware Server have been unified into Kepware Server, currently version 7, and the older names are being retired.

MachineMetrics: How much does MachineMetrics cost?

MachineMetrics does not publish specific pricing rates on its website. The company uses a volume-based subscription model where the more machines you connect, the less it costs per machine. Exact pricing requires contacting the company for a custom quote or booking a demo.

Source
Kepware Server: Is a perpetual licence still available?

Yes for the Windows server, with annual maintenance. Kepware Edge on Linux is subscription-only.

MachineMetrics: What are MachineMetrics' pricing tiers?

MachineMetrics offers three tiers: Core Platform for entry-level machine connectivity, Intelligent MES for mid-tier with ERP integration, and Enterprise for multi-site support with business intelligence. Exact pricing is based on machine count and requires a quote.

Source
Kepware Server: What drives the price?

The number and type of driver suites, not the number of tags on the Windows product. Kepware Edge is priced by tag count.

MachineMetrics: What support is included with MachineMetrics plans?

All MachineMetrics plans include customer support with unlimited remote assistance and training, regardless of tier selection.

Source
Kepware Server: Can I evaluate it before buying?

Yes. The runtime works for two hours at a time without a licence, indefinitely, which is enough to prove connectivity but not to run production.
