I see there are prices for add-ons like Numbapro. But its say it completely free at the top of the home page. I cannot find licensing information.
am i understanding this correctly?
Anaconda itself was completely free, even for commercial use, until April 2020.
Since then, you need to buy a commercial license if you make commercial use of their repositories at https://repo.anaconda.com or the anaconda channel on https://anaconda.org. The term commercial focuses on larger companies requiring more bandwith than a single OSS developer or scientist.
