Great!

I do understand the problem. The problem is real, and this seems like a great developer friendly way to solve it. In my mind, that could probably make it commercially viable by itself, but why don't go a step further? Solve it for non-developers as well:

I might have missed it (which could make it a UX flaw then), but there doesn't seem to be a way to upload tabular data in any form and use that on a template. Why not? You could make it work with csv, javascript supported grid, or maybe some easily parsable spreadsheet format.

Pricing is not my strong suit, so no real comment on that - only that adding an "upgrade account" button to accounts section would be nice.

Good luck!
