The short version

  • Only Weka has a free tier, so it costs nothing to try first.
  • Each has a real cost: Novity novity is a small venture-backed company with a strategic investor rather than a profitable business, so continuity risk is real and the Tokyo Gas investment signals a likely eventual acquisition that would reset the roadmap.; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • They diverge on capability: Novity covers TruPrognostics engine, Weka covers Classification.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Novity

  • Novity is a small venture-backed company with a strategic investor rather than a profitable business, so continuity risk is real and the Tokyo Gas investment signals a likely eventual acquisition that would reset the roadmap.
  • Physics-based models must be configured per equipment class, so each new asset type is an engineering engagement rather than a configuration screen, and rollout speed is limited by Novitys own capacity.
  • Prognostics depend on the quality and sampling rate of your historian data; plants recording ten-minute averages will not get useful remaining-useful-life estimates without new instrumentation.
  • Nothing about pricing is published and there is no self-service entry point, so evaluation always starts with a sales-led pilot on a handful of assets.
  • The deployment footprint is concentrated in oil and gas, LNG and water, so reference customers and pre-built asset models outside those industries are limited.

Weka

  • The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
  • Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture

Questions people ask

Is Novity or Weka better?
Neither clearly leads. Novity starts at On request and Weka at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Novity or Weka?
Weka has a free tier; the other does not. Paid plans start at On request for Novity and Free for Weka.
Does Novity or Weka run on more platforms?
Novity runs on Web, Cloud. Weka runs on Linux, Mac, Windows.
Can I use Weka for free?
Yes. Weka has a free tier, so you can try it without paying. Novity starts at On request.
What is Novity best used for?
Novity is most often used for a gas processing plant that needs a defensible time-to-failure number before deferring a turnaround, an lng terminal with critical compressors and no run-to-failure history to train a conventional model, a wastewater operator whose existing vibration alarms are ignored because they carry no severity or horizon, a generator operator supplying data centre load where an unplanned trip carries contractual penalties. Of those, a gas processing plant that needs a defensible time-to-failure number before deferring a turnaround and an lng terminal with critical compressors and no run-to-failure history to train a conventional model are not what Weka is typically brought in for.
What can Novity do that Weka cannot?
Novity covers TruPrognostics engine, Cold-start modelling, Fault mode diagnosis, Remaining useful life. Weka covers Classification, Regression, Clustering, Association rules.

Answered from the vendors’ own pages

Novity: What does Novity actually output?

A named failure mode and an estimated remaining useful life with a confidence band, not just an anomaly alert.

Weka: What is the cost of Weka software?

Weka is provided at no cost as open-source software released under the GNU General Public License, making it freely available for download and use.

Source
Novity: Do we need failure history to train it?

No. The physics component is what lets it produce useful prognostics on equipment with little or no run-to-failure data.

Weka: Are there commercial licensing options available?

Yes, the project offers information about commercial licenses for organizations requiring non-GPL terms, which can be found in their commercial applications documentation.

Source
Novity: Do we need new sensors?

Often not. It reads from your existing historian, but low sampling rates or missing measurements can require additional instrumentation.

Weka: What support resources are available to users?

Multiple support avenues exist including comprehensive documentation, frequently asked questions, dedicated help resources, and access to courses for learning the platform.

Source
Novity: Who backs the company?

It was spun out of Xerox PARC and took a strategic investment from Acario Innovation, the venture arm of Tokyo Gas, in 2026.

Weka: Is source code access provided?

Yes, developers have full access to source code through the Git repository, along with development documentation and code credits for contributors.
