This is just an open source search I did of tools that can be used in the place of more expensive tools.
Maybe there are some tools that can compete with Tableau? The best of the internet is here now and we can jump on the train to bettering our business and marketing strategies. Try the link for some free alternatives (some subscription based or small fee) to Tableau.
Honestly, I hope you use some of these so I can here how you like them.
