1. The core Mito product is open source. You can see our GitHub here [1]. We also have a pro version that has some additional, code visible, but non-open source features. The way that we think about which features belong in which version of the product is as following: Features that are needed to just get any average analysis done are open source features. On the other hand, features that are specifically useful in an organization -- connecting to company databases, formatting / styling data and graphs for a presentation, etc. -- are pro features. So if you are a team that is relying on our pro features, you're helping support the longevity & progress of Mito. If you are not one of those users and using the open source version, then you will always have access to Mito (and can even help improve it!). Of course the line between what features are specifically helpful in an organization and what feature are needed for an average analysis is a bit blurry, and is a moving target as we continue to expand Mito's offering.
2. Mito is designed specifically to not force users to make a big 'switch'. I've commented this elsewhere in this thread, but just to recap: Because Mito is an extension to Juptyer and because we generate python code for every edit you make, Mito is designed to improve your existing workflow instead of lock you into a new system. Many Mito users use Mito as a starting point! They do as much of their analysis as they can in the Mito spreadsheet and then continue writing more customized Python code to finish up their work.
Not requiring a big switch is nice for the user and its nice for Mito too! Lots of large companies have been able to get up and running with Mito in 30 minutes because it fits into their data stack.
Anyways, not that these are the only two reasons you might feel uneasy about adopting Mito, but at least wanted to share why the switch to Mito might be less scary than switching to other tools.
