It seems that Redash is a BI tool and close source. Ananas is open source, and can be used not only as a BI tool, but also an ETL tool. More over, you can run your pipeline on your own infrastructure, as Ananas can be run on multiple execution engines

Parent commenter linked to their GitHub repo. Redash is open source under the terms of the two-clause BSD license. (Maybe they edited to add link, maybe you overlooked it?)

Oh, sorry about that, my bad. I just looked through redash home page, but didn't find the open source link

The Github link is in the footer of the site, but the icon is very small.
