Looks interesting, but I have some off-topic feedback. I really like that sort of website style, but after 5 minutes looking around I found your site quite confusing.

It wasn't initially apparent that there seems to be both a free and (subscription?) paid version, which had me very confused while reading the 'longevity' page as to how a SaaS is going to last forever. The 'Always Free' box isn't very clear that it describes a different product version (no download button, not clearly a standalone feature list) and the text on the far left is basically background noise.
