Reviewers mostly praise Sanity.io for strong developer experience, fast setup, and deep flexibility in modeling structured, omnichannel content; several say customization in Studio and features like portable text and image hotspots make it well suited to creative client work. The makers of
Sheet Ninja similarly say it was easier to customize than other CMS tools. Still, criticism is sharp around plugin reliability, weak internationalization and TypeScript support, limited built-in UI elements, outdated documentation, and a frustrating editor and data-sync model for some teams.
