A: Our team took a look at Carrd, and it appears to support adding custom JavaScript to websites. Since Onvocado works with any platform that allows JavaScript, you should have no issues embedding it on Carrd.

As for ConvertKit, we've added it to our feature request board (https://trello.com/b/erpaGpU3/onvocado-feature-requests). Feel free to vote for it, and if enough users show interest, we can prioritize its development. Let us know if you have any other questions!
