The short version

  • Each has a real cost: Dyndrite the value depends on writing Python; a shop without an engineer who codes gets a more expensive version of the build preparation software their machine already came with.; 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.
  • They diverge on capability: Dyndrite covers Accelerated Computation Engine, Kepware Server covers 150-plus device drivers.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Dyndrite

  • Running redundant collection servers so a cloud analytics pipeline does not lose data during Windows patchingnot Dyndrite

Where each one falls short

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

Dyndrite

  • The value depends on writing Python; a shop without an engineer who codes gets a more expensive version of the build preparation software their machine already came with.
  • No pricing is published anywhere and it is frequently sold through machine OEM catalogues, so the price you are quoted may depend on which printer vendor you buy through rather than on the software itself.
  • It requires a supported NVIDIA GPU, which rules out the shared virtual desktops many manufacturing IT departments standardise on and adds a hardware line to the purchase.
  • Scope is narrow: it is aimed at metal laser powder bed fusion, so polymer, binder jetting and directed energy deposition users are largely outside its target.
  • It is a small independent vendor with a correspondingly small community, so training material, third-party expertise and hiring for the skill are all harder than for OEM tools, and the OEMs it depends on for machine formats are also its competitors.

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.

Answered from the vendors’ own pages

Dyndrite: What does Dyndrite cost?

Nothing is published. It is quoted per seat annually and is also resold through machine OEMs, including Nikon SLM Solutions.

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.

Dyndrite: Do I need to write code to use it?

You can use it without scripting, but the reason to choose it over OEM software is the Python API. Without that the case is weak.

Kepware Server: Is a perpetual licence still available?

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

Dyndrite: Which printers does it support?

LPBF Pro produces build files for machines from Aconity3D, Additive Industries, EOS, Nikon SLM Solutions, Renishaw, Velo3D and Xact Metal, among others.

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.

Dyndrite: Does it need special hardware?

Yes. The engine is GPU-accelerated and expects a supported NVIDIA GPU.

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.
