Sanity vs Storyblok

Sanity

There is a graphical editorial calendar plugin inside the Studio with schedule review, configurable author display and scheduled publishing, but it only runs on the deprecated Studio v2 and has itself been replaced by Scheduled Publishing. Briefs like the image-brief guide are schemas a team models itself, with status values such as draft, in review and approved; we found no evidence of grouping by campaign or channel, per-person workload or deadline views, or briefs carrying goal, audience and keywords as a product feature.

Storyblok

Workflow stages carry assignees, due dates and email notifications, and single story scheduling gives a publish date — that is a status view with dates, not a plan. We found no public information on an editorial calendar across channels, briefs carrying goal, audience and keywords to the writer, or content grouped by campaign, topic or channel; the campaigns material captured is an on-demand marketing session, not product documentation.

Sanity

Comments and tasks ship on all paid plans with mentions and role permissions, Editorial Workflows add configurable stages, assignments and durable history beside the documents being edited, a complete change history is retained per plan, and a full audit trail with a History API and custom roles is gated to Enterprise. We found no public information on inline suggested edits, guest or freelancer access limited to assigned pieces, or scheduled publishing that waits for approval — the scheduling plugin discards newer drafts at publish time rather than holding for a reviewer.

Storyblok

Publishing is genuinely gated: only stories at Ready to Publish can go live, with per-stage edit and publish permissions, assignment to a person or role, due dates, comments and a history of stage changes, plus a documented approval app with email sign-off and changelog review that is discontinued in v2 in favour of discussions and workflows. What I cannot see is the part I answer for: we found no public information on mandatory legal or brand reviewers, freelancer access scoped to assigned pieces, or an approval trail preserving the exact version each approver released — audit trails appear only as a homepage claim tied to enterprise tiers.

Sanity

Content is stored as structured JSON in the Content Lake with a configurable model, relationships between entries, unlimited content types and locales on every plan, AI translation of whole documents or single fields with formatting retained, and multi-variant creation. We found no public information on field-level localisation with fallback languages, translation workflows with status per locale, or a documented self-service export — the only export on record is the copy in Sanity's standard database export format within thirty days after termination.

Storyblok

Content lives as a real model — fields, blocks and stories with components and content types, reusable nestable blocks, reference fields linking entries, a block library with folders and tags, and component schemas maintainable in a single parent space — and translated stories sit alongside each other with per-language publication status. Delivery is JSON through documented APIs, so the repository is readable in a documented format; we found no public information on field-level localisation with fallback languages, variants per market, named translation-service connectors, or a documented self-service export of content, model and assets together.

Sanity

An API-first architecture with GROQ and GraphQL, a Live CDN, webhooks, a CLI and named integrations with fourteen front-end frameworks plus Vercel-hosted templates takes content to websites, apps and other channels from one place, well past basic publishing. The captured pages show plan-level request and bandwidth quotas rather than published API rate limits, and we found no public information on a public status page, a maintained connector directory for marketing-stack tools, or per-piece performance data pulled back from analytics.

Storyblok

Delivery is the core of the product: versioned GraphQL alongside REST with a published rate limit of 100 points per second, webhook endpoints manageable through the management API, an app directory, named framework support, scheduled story publishing, a public status page, an uptime SLA on the Content Delivery API and thirty days' notice before breaking changes. What keeps it from the top for a content team: we found no public information on per-piece performance data pulled back from analytics or performance attributed per channel.

Sanity

AI Assist drafts long-form text from a title, translates documents or fields, generates images and builds variants, and the AI terms state that all configurations explicitly prohibit or disable training on input data, with OpenAI, Anthropic, Pinecone and Google named as the providers receiving it. Those same terms route input data to those US providers, keep it in archives or caches for "a few days", allow technology-partner changes without notice, reserve the right to change credit consumption rates immediately, and are silent on EU processing, EU AI Act marking of generated text and explicit assignment of output rights to the customer.

Storyblok

The AI features are described concretely — translations, alt text, SEO — with providers and models named for OpenAI, Google Gemini and Anthropic Claude, admin enablement at space or organization level, the option to use your own credentials and preferred model, brand voice context with natural-language output rules, and usage dashboards filterable by provider, feature, user and space. The rights questions I need answered before anything goes live are open: we found no public information on whether customer content trains the models, retention periods for prompts and outputs, who owns generated output, or labelling of generated text under the EU AI Act — the AI Terms are referenced in the terms but their content was not captured.

Sanity

A data processing addendum and a privacy policy under Norwegian law with standard contractual clauses for transfers are offered, which clears the floor. But the agreement is governed by California law with exclusive venue in San Francisco, the site is hosted in the United States, the Google Cloud Platform region is not stated, and the AI terms name US providers receiving customer input data; we found no public information establishing EU hosting for content or an AI processing location.

Storyblok

A privacy policy and a data processing agreement are offered, and the imprint names Storyblok GmbH of Linz, Austria as operator — but the terms state services are provided by a Storyblok Group company specifically named in your contract, with separate term sets for Americas customers, so the contracting entity is not established on the vendor's own pages. Hosting is on AWS without a stated region, the delivery regions list the European Union alongside the United States, Canada, Australia and China, and we found no public information on where AI prompts are processed or on European ownership.

Sanity

Free at $0 and Growth at $15 per seat per month are published with billing period and the main limits, and overages are priced line by line — $0.30 per 1GB bandwidth, $0.50 per 1GB assets, $1 per 25K API requests — alongside add-ons at $299 and $999 per month and AI credits at $0.05 per credit with per-action costs; Enterprise is named as the plan that unlocks SSO, the audit trail and the uptime SLA, and contract, renewal and increase conditions are stated in the terms. Full annual cost stays a sales conversation for anyone needing those Enterprise gates, since annual payment exists only on the custom-priced Enterprise plan.

Storyblok

The self-service tiers are unusually complete: Starter free, Growth at 99,00 €/month and Growth Plus at 349,00 €/month, each stating seats, locales, traffic, API requests and AI credits, with per-unit overages published — 15,00 €/month each additional user, 20,00 €/month per additional locale, 75,00 €/month for each 250GB extra traffic, 10,00 €/month per 1M API requests, 20,00 €/month per 200k AI credits — and one month free when paying annually. The gap for a buyer: Premium and Elite are listed as Custom with sales contact, and that is where single sign-on, custom roles and workflows sit; custom workflows are only said to be available on some pricing plans, and we found no public information on the cost of exporting or leaving the platform.
