In general, you can't iframe Notion because they have X-Frame-Options set to SAMEORIGIN (as do most sites). However, I'm wondering if setting up my public Notion page on my mysubdomain.mydomain.com will allow me to then iframe it on mydomain.com. 

Does anyone know if this is possible?
Currently I don’t think this will work but in the next update we have coming out soon doing this should be fine
Hey Kaelin! Yes this should be possible with our Super Static feature, since we'll be rendering the sites on our end and won't enforce that rule. Coming very soon!
Exciting stuff! Any chance this is something that will be done in the next week or two? Our startup is launching an alpha version of a product, and this would greatly simplify things for our use-case.
