Prismic

Prismic is a headless content management system that stores content centrally and delivers it to any front end over an API. Founded in 2013 and based in Paris, it is built around reusable content "slices" that let marketing teams assemble pages from components developers have defined.

Prismic hosts uploaded media on its own image CDN, which serves files from the prismic.io domain with on-the-fly resizing and format conversion. Images pulled into email campaigns from that CDN indicate Prismic is the content source behind a brand's site and campaign assets.
