How much does Weka cost?

Weka publishes a single tier, Open Source, at Free.

Does Weka have a free plan?

Yes. The Open Source tier costs nothing and covers all ml algorithms, gui and cli, java api.

Which machine learning & data science tools can I use without paying?

8 of the 8 machine learning & data science tools listed alongside Weka have a free tier: Comet ML, BentoML, Anaconda, Azure Machine Learning, BigQuery ML.

Does Weka charge per user?

The record carries a price and a billing period for each of its 1 tiers, but not the unit that price is charged in. Per-seat and flat-rate billing look identical in this data, so check the vendor's page before budgeting for a team.

They are what the catalogue entry holds, refreshed when the entry is. Vendors change pricing without notice and nobody at Softwr re-verifies each tier by hand, so treat this as a structured summary and the vendor's own pricing page as the authority.

What should I compare Weka against before paying?

The closest machine learning & data science tools in this directory are Comet ML, BentoML, Anaconda, Azure Machine Learning. Each has a side-by-side comparison with Weka covering price, platforms and features.

People bring Weka in for teaching and exploring classic machine learning algorithms through a gui, running data mining experiments and preprocessing without writing code. If that is not the job you are buying for, the alternatives to Weka are worth a look before you commit to a tier.

How that compares in Machine Learning & Data Science

Too few machine learning & data science tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the Weka badges page.

Before you pay for Weka

Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.

What it can tell you is the shape of the ladder: a single tier at Free. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.

Weka runs on linux, mac, windows, and is published by University of Waikato of Hamilton, New Zealand. The full record is on the Weka review, and the rest of the category is under best machine learning & data science tools.
