A: Hi. Thank you for reaching out.

We don't support Gutenberg, at this point. But this is, of course, on our wish list. We do not know Stackable, but i guess it will not work in this case either.

You can use other page builders like Bricks, Elemtor and Divi currently!

If you have any further questions feel free to send us an e-mail on info@seogenerator.io.

Kind regards,
Tim & Jeroen
