What is Sanity?

Sanity, sometimes called Sanity.io, is a headless CMS where both the content schema and the editing studio are defined in code. Content is stored as structured JSON and delivered via API to any front-end. The Studio — the back-end interface editors use — is a customizable React application teams can shape to fit their workflow. The question of what is Sanity CMS usually comes up when teams outgrow WordPress.

Why it matters

Most CMSes give you a fixed editing experience and ask your content to fit inside it. Sanity flips that. The schema is yours. The Studio is yours. If your marketing team needs a specific publishing flow, you build it. If your content model has nested case studies linked to authors linked to industries, you model it that way and the Studio reflects it. It is the closest thing to a content operating system the off-the-shelf market has. Sanity is Roelu's default CMS for a reason — it scales with the business instead of forcing the business to scale around it.

How it works

You define your content types — pages, posts, authors, products — as JavaScript schemas. Sanity generates a Studio that matches: forms, fields, references, validation. Editors log in, work inside that Studio, and hit publish. Content syncs to Sanity's Content Lake, a real-time database. Your front-end queries it with GROQ or GraphQL and renders pages. Need a new content type next quarter? Add it to the schema and redeploy the Studio in minutes. Live preview, draft mode, and full version history come built in, so marketing can see changes before they go live and roll back anything that goes wrong without calling engineering.
