Ask HN: Good Landing Page Tool for Rails Site?

Hi all. I have a rails site that mostly does what I want it to do for core business/user stuff but am thinking of adding a really idiot proof CMS solution so people on the team can make quick landing pages for marketing campaigns, email blasts, etc.

Everyone seems to like Webflow for no code quick sites like this right? Is that a good choice to bolt on to a rails site or am I missing something obvious?
