Any thoughts on the best way to make this more obvious to new users? Just some copy on the front page saying you can test without an account? Or perhaps focus on the fact that there will be a "sandbox" where you can test everything right away with canned data(?)
For me personally it's fine as it is - I was simply positively surprised to see that I got to play around with it without creating an account first.
I suppose you could get more users that have a lower interest in the product to try it by adding either one or your solutions. Those that have a higher interest off the bat will click "Getting started" anyways (and expect to get an "Open account" dialogue).
