Prismic vs Sanity

GROQ and Portable Text enable union types, nested arrays, and custom input components, all first-class.

Custom Types are solid but lack union or polymorphic fields. Complex relational structures need workarounds.

Objects and Portable Text blocks are shared across document types and map directly to your design system.

Slices are purpose-built for reuse, defined once in Slice Machine and shared across all page types.

Custom validators work in schema definitions but require developer-written JavaScript, not a no-code option.

Validation limited to required marking. No regex, character limits, or custom validators without custom field plugins.

Studio is highly customizable but needs developer configuration before non-technical editors are comfortable.

The Page Builder is the most approachable editor, picking a slice, filling fields, and publishing takes minutes.

The Presentation tool offers click-to-edit live previews but requires developer config to connect your frontend.

Slice Simulator gives live previews during development. Editors can share a preview link before publishing.

Content Releases and versioning built in. Custom workflow states need Studio customization or third-party plugins.

Draft, in-review, and published states built in. Batched Releases available. Approval chains need the Platinum plan.

Imgix-powered CDN with hotspot and crop built in. Asset manager handles images, files, and custom sources.

Media library handles uploads and basic organization. Imgix powers delivery but no focal point UI or transform control.

Presence indicators, cursor tracking, and simultaneous editing are core to Sanity Studio, not a bolt-on.

No real-time simultaneous editing. Prismic uses document locking, one editor holds a document at a time.

Role-based access per content type on paid plans. Field-level permissions need custom Studio configuration.

Admin and writer roles cover basic access. Granular custom roles need Enterprise plan. No field-level access control.

Field-level localization via @sanity/language-filter, well maintained but requires schema wiring by a developer.

Field-level locale variants and a clean translation UI. Multiple locales per repository supported on all plans.

Fallback logic must be implemented in GROQ queries or the frontend, no native CMS fallback configuration.

Fallback must be handled in the query layer or frontend, the API returns null for missing translations.

GROQ docs, REST reference, GraphQL playground, and schema-generated TypeScript types are all excellent.

REST and GraphQL APIs are well documented. @prismicio/client generates TypeScript types from your Slice Machine config.

Starters for Next.js, Astro, Nuxt, and SvelteKit. next-sanity is the most polished CMS integration in Next.js.

Slice Machine is the best first-run setup, Next.js and Nuxt adapters configure routing, previews, and types.

Mutations API, Assets API, and GROQ support any programmatic workflow. Sanity CLI handles migrations and dataset ops.

Write and Migration APIs support programmatic content and bulk ops but are less mature than alternatives.

Multiple datasets provide isolation but promotion needs manual scripting. Enterprise adds dataset aliases for hot-swap.

Environments are Platinum/Enterprise only, scoped to schema testing. Prismic recommends production Releases for review.

Edge CDN with Imgix image transforms. Fast globally but slightly behind Fastly-backed competitors on cold-start latency.

Content via Fastly's global edge. One of the better-performing CMS APIs on cold-start latency benchmarks.

Fully managed cloud with zero server config. Studio can be hosted anywhere or embedded in your app.

Fully managed SaaS with zero infrastructure to configure or maintain.

Sanity Exchange has plugins for forms, SEO, and AI. Core integrations are solid but third-party quality varies.

Slice Machine-centric ecosystem with strong Next.js and Nuxt integrations. Fewer marketplace plugins than others.

One of the most active CMS communities, Slack is genuinely helpful, docs are thorough, and release cadence is high.

A small but helpful community. Forum support is responsive but fewer tutorials and plugins than larger CMS platforms.
