As of 28 Oct 2026, the panel rates Sanity 3/5 and Storyblok 3/5 in Content Marketing. Weighted by what each judge cares about, 2 of the 6 judges pick Sanity and 2 pick Storyblok, 2 call it a tie. Sanity scores higher on 3 of 7 criteria (Planning, editorial calendar & briefs, AI assistance & content rights and Pricing transparency). Storyblok scores higher on 3 of 7 criteria (European sovereignty, Publishing, distribution & integrations and Creation, review & approval). Provenance — Sanity: Rest of world; Storyblok: EU-Made. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
The panel splits: weighted totals favor Sanity for the content lead (5.6 to 5) and the skeptic (5.8 to 5.7), Storyblok for the web engineer (6.4 to 5.9) and the SME marketer (5.4 to 5.3); the localisation lead and the data protection officer tie at 5.8 to 5.8 and 5.3 to 5.3. By criterion, Storyblok is ahead on distribution and integrations (7.3 to 6.3, 6 judges lean Storyblok) and sovereignty (4.3 to 3.0, 5 lean Storyblok, 1 tie); Sanity is ahead on AI and content rights (5.5 to 4.3, 6 lean Sanity), editorial planning (4.2 to 3.0, 5 lean Sanity, 1 tie) and pricing transparency (7.8 to 7.2, 4 lean Sanity, 2 ties). Content model and reuse ties 6 judges at 6.2 to 6.2; collaboration and approval splits 3 judges for Storyblok, 1 for Sanity, 2 ties. The bench's split, not a single lean, is the answer.
Choose Sanity if
You need written controls on AI training: the Sanity verdict records training on transferred input data as prohibited or disabled, and AI and content rights leans Sanity 6 judges to 0 (means 5.5 to 4.3).
Your editorial team needs configurable workflow stages with durable history plus comments and Tasks on paid plans; editorial planning leans Sanity 5 to 0 with 1 tie (means 4.2 to 3.0).
You model spend per seat: Sanity lists Free at $0, Growth at $15 per seat per month, viewer seats free and overages priced line by line; pricing transparency leans Sanity 4 to 0 with 2 ties (7.8 to 7.2).
Your team's weighting resembles the panel's content lead, whose weighted total reads 5.6 for Sanity against 5 for Storyblok.
Choose Storyblok if
You need delivery infrastructure with published operational figures: the Storyblok verdict records a versioned GraphQL API with a published rate limit of 100 points per second, webhooks, an app directory and a public status page; distribution and integrations leans Storyblok 6 judges to 0 (means 7.3 to 6.3).
You require a European legal entity: legal entity jurisdiction is listed as AT, and the verdict records an Austrian operator, ISO 27001 and a data processing agreement — while the same verdict records hosting on AWS with no region stated, services provided by a Storyblok Group company named in the contract, and no established location for AI processing; sovereignty leans Storyblok 5 to 0 with 1 tie (4.3 to 3.0).
Your team weighs collaboration and approval heavily: that criterion leans Storyblok 3 judges to 1 with 2 ties (means 6.5 to 6.2).
Your priorities match the panel's web engineer, whose weighted total reads 6.4 for Storyblok against 5.9 for Sanity.
Read this comparison as one judge. Each weighs the same scores by what they care about.
The Data Protection Officer
Signs off every tool that stores the company's drafts, author profiles and campaign data. Wants the contracting entity and hosting region named, the subprocessor list with the AI providers on it, prompt retention in days, and training on customer content excluded in the terms rather than in a blog post.
Sanity
Storyblok
This judge calls it a tie.
Criterion by criterion
Planning, editorial calendar & briefs
Sanity
The captured pages show a graphical editorial calendar as a Studio plugin, but the pages state that plugin is deprecated and only works on the deprecated Studio v2; the newer editorial workflows surface documents stages, assignments and durable history alongside documents without a calendar view. Briefs appear only as a do-it-yourself schema in a modelling guide, and we found no public information on grouping content by campaign or topic, workload views per person, or recurring formats scheduled as series.
Storyblok
Publication is staged and scheduled: a default workflow of Drafting, Reviewing and Ready to Publish applies to all content types, stage moves carry an assignee and a due date, and single-story scheduling is a listed plan feature. Beyond an Ideation Room for drafting and improving articles, we found no public information on an editorial calendar across channels, grouping of content by campaign, or briefs carrying goal, audience and keywords. The campaign references we captured are webinar sessions, not product capabilities.
Creation, review & approval
Sanity
Comments and tasks on documents, plan-dependent draft history and review statuses are evidenced on paid plans, with viewer seats free and the full audit trail, History API and custom roles gated to the Enterprise plan. The workflows surface documents stages, assignments and decisions routed to people, but we found no public information on configurable multi-step approvals, mandatory reviewers such as legal or brand, or freelancer access limited to assigned pieces.
Storyblok
Workflows are configurable — relevant content types, default stage, edit and publish permissions per stage, stage order and automatic progress — with comments, a history of stage changes, and publication gated to the final stage, while custom workflows and language-specific workflows sit in higher tiers. An approval app that collected email sign-off on a reviewed changelog is documented as discontinued in v2, with discussions and workflows as its successor. We found no public information on mandatory reviewers, freelancer access limited to assigned pieces, or an audit log of every edit, approval and publish with user and timestamp beyond the homepage's mention of audit trails.
Structured content, localisation & export
Sanity
Content is stored as structured JSON in the Content Lake with a documented content model, references between entries, unlimited content types and locales on all plans, queried through GROQ and GraphQL, and the AI features translate whole documents or single fields and create variants for A/B testing. A copy of subscriber data is provided in the vendor's standard database export format within thirty days after termination, but we found no public information on field-level locale fallback, named translation-service connectors, or documented re-import and migration tooling in both directions.
Storyblok
Content is modelled as fields, blocks and stories under component and content-type schemas, with nestable reusable blocks, reference fields linking entries, datasources for shared terminology, and component definitions inherited across sites from a nominated parent space. Translated stories carry a per-language publication status, and content is delivered as JSON through documented APIs. We found no public information on a documented, self-service export of the whole repository with model and assets, on fallback languages, or on named translation-service connectors.
Publishing, distribution & integrations
Sanity
The platform is API-first, delivering content to websites, apps and other channels through two documented query languages, with a live CDN, webhooks, a CLI, functions and an MCP server, and named support for a long list of frontend frameworks plus Vercel-hosted templates. We found no public information on preview environments, per-piece performance data pulled back from analytics, a status page or an API deprecation policy, and the uptime SLA is stated only for the Enterprise plan.
Storyblok
The GraphQL API is versioned with published rate limits — 100 points per second, status code 429 on excess — and delivery endpoints in a European Union region among five, webhooks can be created, updated and listened to per space, an app directory and a public status page exist, and mobile SDKs are documented. A thirty-day notice for breaking changes and a delivery uptime SLA per plan are written into the terms. We found no public information on performance data per piece pulled back from analytics.
AI assistance & content rights
Sanity
The AI terms name OpenAI, Anthropic, Pinecone and Google as receiving customer input data and state that all configurations explicitly prohibit or disable training on data transferred to those providers, and the subscriber can stop using the AI services at any time — a training exclusion in the terms, which is where I want it. Retention is given only as data persisting for a few days in provider archives, the provider list may change without notice during development, and we found no public information on the processing location for AI features, an admin switch-off, EU AI Act marking of generated text, or output rights assigned specifically for generated content.
Storyblok
Model providers and models are named — OpenAI, Google Gemini and Anthropic Claude — features can be enabled or disabled at space or organization level, organizations can require their own credentials, and usage history is filterable by provider, feature, user and space. The general terms route AI use into dedicated AI Terms, but the captured AI Terms pages show only archive periods: we found no public information on prompt or output retention in days, the processing location for AI, a statement in the terms that customer content is excluded from model training, ownership of generated output, or EU AI Act marking of generated text. The published subprocessor list names website, marketing and support providers; the AI providers appear only in the AI documentation.
European sovereignty
Sanity
A privacy policy and a data processing addendum are offered with standard contractual clauses for transfers out of the EEA, and a Norwegian entity sits beside the US one in the privacy policy — but the agreement is governed by California law with exclusive venue in San Francisco, the site is hosted in the United States, and Google Cloud Platform and the US AI providers process customer data with no stated region. We found no public information on where content, assets and AI prompts are hosted, so EU hosting is not established, and the vendor may change AI partners without notice.
Storyblok
The website operator is Storyblok GmbH, Peter-Behrens-Platz 2, 4020 Linz, Austria, register number FN 479743 f with Austrian court jurisdiction, and a data processing agreement governs customer content under an ISO 27001-certified information security system. The terms state that services are provided by 'a Storyblok Group company, specifically named in your contract', so the contracting entity is not fixed on the public pages, and we found no public information establishing where customer content, assets and AI prompts are stored or processed. The privacy policy publishes a subprocessor list with locations and purposes, though it covers website, marketing and support processing, and the GraphQL delivery API offers a European Union region alongside four others.
Pricing transparency
Sanity
The free and Growth plans are priced at fifteen dollars per seat per month with quotas and overage rates stated for API requests, bandwidth, assets, compute, AI credits and embeddings, add-on prices published, viewer seats free, and the plan unlocking SSO, the audit trail and the uptime SLA named, though that plan is custom-priced. Contract and renewal conditions — twelve-month terms, sixty-day non-renewal notice, annual fee increases with thirty days' notice, and monthly-only billing on self-serve plans — are public, but we found no published cost for exporting or leaving the platform.
Storyblok
Self-service plans are fully priced: Starter is free, Growth at 99,00 €/mo and Growth Plus at 349,00 €/mo, each stating seats, traffic, API requests, locales and AI credits, with public unit prices for extras (15,00 €/month per additional user, 75,00 €/month for each 250GB extra, 10,00 €/month per 1M API requests, 20,00 €/month per additional locale, 20,00 €/month per 200k AI credits) and one month free when paying annually. Contract mechanics are stated: a one-year default term, automatic renewal with thirty days' notice, and the tax percentage shown before subscribing. Premium and Elite — the tiers carrying custom roles and workflows, SSO and SCIM — are priced 'Custom' and enterprise overages are billed at Order Form rates, so an annual cost is computable only for the self-service tiers.
