Reviewers largely praise Sanity.io for strong developer experience, fast setup, and deep customization, especially for structured or omnichannel content. Users like features such as portable text, image hotspots, and the flexibility of Studio v3, with several saying it works well across multiple projects and creative client sites. Still, criticism is sharp when workflows break: plugin support can be inconsistent, documentation and official examples feel thin, and some dislike the editor layout. One user also reports frustrating schema-data sync issues, especially for smaller projects.
