Firstly we’ve looked at all of these options and as developers got pretty excited by their potential. The problem was that we found them to all be lacking in some degree, Snipcart is only for the most basic ecommerce, Ecwid is focused more on widgets, and Foxycart requires you to use their hosted checkout.

Secondly every member of our team has been in a position at some point in their working lives where we’ve had to build applications that support all manor of strange legacy requests. We completely understand.

Yes, if you use our javascript SDK with the API, you would require javascript for it to work. That said, you could take the backend approach and then there would be no issues with supporting older clients or applications as it would all be handled by the servers.

We have been thinking about adding a hosted checkout page for exactly the reason you describe. it would probably be an option so that you can either use a hosted checkout page quickly, or if you want more control you can use one of our SDKs and build your own checkout.

Thanks for wishing us luck!
