I have a headless shop using Storefront API and the client currently uses a landing page builder app, pagefly, that doesn't expose any data in the Storefront API.
Is there a recommended approach to give a client a landing page builder feature that works with Storefront API?
There's https://www.builder.io/ (This is not an endorsement as I've not used it).
Personally we're using a headless CMS for our landing pages. We use Prismic but there's also Contentful.
