The models' case: Structured content model with a real query language (GROQ), fully customizable Studio you host in-repo, best-in-class real-time collaboration and content previews for. The models' main caveat: Not for non-technical teams wanting turnkey visual page editing out of the box. The strongest alternative is Storyblok — Market-leading visual page builder with intuitive nested component blocks and robust out-of-the-box localization, allowing non-technical marketers to.
