Absolutely! I would hope that any popular offering would have competitors. And I would expect that the creator of the linked service would at least notice that you offer only an iframe embed, as opposed to my SEO friendly JS embed. And I guess you would have to know if one was released before the other. I am sorry if we had similar ideas.

I’ve got a few Notion products. Would love to connect. Feel free to reach out at the domain linked in my profile.
