How is this data science ranking decided?

Mechanically. The 1 approved data science listings on this page are sorted by their published rating, highest first, with the number of ratings behind each score as the tie-break and the product name as a final tie-break so the order is stable. Those ratings are aggregated from public sources, not collected from Softwr readers, this site hosts no reviews, so the order is a summary of what is already published elsewhere, not a verdict of our own. Nothing on this page is paid placement.

Is this list re-ordered for startups?

No, and it would be dishonest to imply otherwise. The catalogue records no data about which team sizes or roles each tool suits, so the ranking is the same published-rating order as the unsegmented list. What the startups framing changes is which of the figures below matter most. Startups are buying for a headcount they do not have yet, which makes the second and third tier of each ladder more important than the first. Check what the price becomes at ten people.

Is there free data science software?

Yes, 1 of 1 tools in this category publish a plan priced at $0. 1 of them are free outright, with no paid tier above. A tool is only counted as free here when it publishes a $0 plan, an open-source licence, or a starting price of zero, a free trial does not count.

How many data science tools are listed on Softwr?

1 approved data science listings appear on this page, including Python. Each links to a full breakdown with its pricing tiers and plan detail, and the category can be filtered by price and sorted by rating above. You can also read the shortlist view at /best/data-science, which ranks the same set by published rating.

How this ranking is derived

The sort key

Published rating, highest first. Ties break on the number of ratings behind the score, then on product name so the order never depends on what the API happened to return first. That is the whole rule, there is no weighting, no score of our own, and nothing paid: no sponsored slot runs on these pages.

Where the ratings come from

No listing in this set carries a rating, so the order falls back to name. Those scores are aggregated from public sources rather than collected here, Softwr hosts no reviews of its own, which is also why no rating on this page is marked up as ours in structured data.

What the pool is

Approved data science listings, capped at 20 per page; 1 came back for this one. It is not the whole market, and a tool being absent means we hold no record of it rather than that it failed a test. The unranked full set is on the data science category page.

What data science software costs

Counted from the published pricing of the 1 listing on this page. A tool counts as free only where it publishes a $0 plan, an open-source licence or a starting price of zero.

Publish a $0 plan: Yes

The one listing here publishes a $0 plan, and 1 of those charge nothing at all.

How these vendors bill

The billing model each of the 1 data science listing publishes, counted. Two tools at the same headline price are not the same purchase if one of them charges per seat.

open-source: 1

How to choose between them

Four things the numbers above should change about your shortlist.

Start with the free tiers if there are enough of them

1 of 1 data science tools here publish a $0 plan, which is enough to run a real trial without a purchase order. A free tier is worth more than a free trial when you are evaluating: a trial expires on the vendor's schedule, a free plan expires when you outgrow it. The thing to check before you commit is which of the capabilities below sit above the free line.
