Absolutely right!

Everyone launching a beta version of their product says its free. You invest time learning and migrating things over and by the time they catch up on features, pricing page shows up.

I have been using https://www.erdlab.io for 6 months now and so far it looks like they are true to their word. The developers on ERDLab have fulltime jobs and treat it as a side project but still push out updates and handle maintenance in a timely manner. I want them to succeed but not so much where they start to think about making money lol
