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 Skeptic
Has read "AI-powered content at scale", "one source of truth for every channel" and "no lock-in, it's headless" on every page in this category. Reads instead for the export that includes locales and history, the clause on training with customer content, and what the invoice does when the third locale and the API overage arrive.

Criterion by criterion
Planning, editorial calendar & briefs
Sanity
A visual editorial calendar exists as a Studio plugin with schedule, reschedule and unschedule actions, but the captured page notes the plugin is deprecated, tied to the deprecated Studio v2, and it does not perform publishing by itself — the documentation advises an external cronjob or webhook script to fire the publish event. Current planning strength sits in Editorial Workflows, which shows stages, assignments, actions and history beside the documents people edit. We found no public information on campaign grouping, briefs carrying goal, audience and keywords to the writer, workload or deadline views per person, or coverage-gap reporting; briefs appear only as a do-it-yourself schema example for image production.
Storyblok
Workflow stages can carry an assignee and a due date, stories can be scheduled, and an Ideation Room supports drafting articles, which amounts to a list of content with statuses and publish dates. We found no public information on an editorial calendar across channels, briefs carrying goal, audience and keywords, or content grouped by campaign, topic or channel.
Creation, review & approval
Sanity
Comments and Tasks ship on all paid plans, stored in a parallel dataset with documented permission requirements, and Editorial Workflows adds configurable stages, assignments and durable history that can be driven from the CLI or custom interfaces. A complete history of all changes to a dataset, including deleted documents, is retained for a plan-dependent period. The full audit trail with the History API, custom roles and access control, and SAML single sign-on are listed as Enterprise-plan inclusions, and we found no public information on mandatory reviewers, freelancer access limited to assigned pieces, or scheduled publishing that waits for approval.
Storyblok
Customizable workflows set per-stage edit and publish permissions, gate publishing on a final stage, and keep comments and stage-change history, with email sign-off via an Approval app that the pages state is discontinued in v2 in favour of discussions and workflows. Audit trails are claimed only as an enterprise bullet on the homepage; we found no public information on guest or freelancer access limited to assigned pieces, inline suggested edits, or approval versions preserved and exportable, and language-based workflows support no per-language assignees.
Structured content, localisation & export
Sanity
Content lives as structured JSON in the Content Lake behind a model defined in TypeScript or JavaScript, with references between entries, unlimited content types and unlimited locales on every plan, plus variants for A/B testing and one-click AI translation described. On exit, the terms promise subscriber data in Sanity's standard database export format within thirty days of termination, with no obligation to maintain data past that point. We found no public information on field-level localisation with fallback languages, translation workflows with status per locale and named translation-service connectors, or documented re-importable migration tooling in both directions.
Storyblok
Components and content types, nestable blocks, reference fields between entries, datasources, component schemas inherited from a parent space, and per-language publication status for translated stories show a real reusable content model with locales. We found no public information on a documented self-service export of content, model, locales and history, on field-level fallback languages, or on named translation-service connectors; the enterprise backup option to the customer's own cloud is off by default.
Publishing, distribution & integrations
Sanity
This is API-first delivery: GROQ and GraphQL, a Live CDN, GROQ-powered webhooks, a CLI and named framework integrations from React and Next.js through Astro and Eleventy, with content consumable by anything that can consume an API. The named integrations are delivery frameworks rather than CRM or analytics tools, and the uptime SLA appears as an Enterprise-plan inclusion. We found no public information on published API rate limits, a public status page, an API deprecation policy, or performance data pulled back per piece from analytics.
Storyblok
A versioned GraphQL API with a published rate limit and status code 429 on excess, a REST API recommended as more feature-rich, webhooks creatable and updatable by API and triggered on workflow stage changes, an app store, mobile SDKs, a status page, delivery SLA percentages per plan, and a 30-day breaking-change notice. We found no public information on performance data pulled back from analytics per piece or attributed per channel.
AI assistance & content rights
Sanity
The AI terms name OpenAI, L.L.C., Anthropic, PBC, Pinecone Systems Inc. and Google Inc. as third-party providers receiving input data, and state that all configurations explicitly prohibit or disable model training on data transferred to them, with uploaded data possibly persisting for a few days in provider archives and caches. Usage is metered in AI credits at $0.05 PER AI CREDIT, with agent queries and actions costed at 4 and 2 credits and monthly allocations that expire without rollover. We found no public information on ownership of generated output assigned in the terms, admin-level switch-off of AI features, EU processing locations for AI, or marking of generated content for EU AI Act transparency.
Storyblok
Providers and exact models are listed for OpenAI, Google Gemini and Anthropic Claude, admins can enable features at space or organization level and bring their own credentials, and usage history is filterable by provider, feature, user and space. The AI terms surface only as archived date ranges; we found no public information on whether customer content trains the models, on EU processing for AI features, on prompt and output retention in days, on output ownership, or on marking generated content for EU AI Act transparency.
European sovereignty
Sanity
A data processing addendum is offered, the privacy policy runs under Norwegian and EU GDPR with standard contractual clauses for transfers outside the EEA, and content is processed on Google Cloud Platform with the server region not stated, while generative AI input data goes to the US providers named in the AI terms. The agreement is governed by California law with exclusive venue in the state courts of San Francisco. We found no public information on EU hosting for content and assets, a subprocessor list with locations and purposes, or a self-hosting or European cloud option.
Storyblok
The pages show an Austrian operator in Linz with register number, court and VAT, a data processing agreement required for customer content, ISO 27001, the European Union among the GraphQL delivery regions, and a subprocessor list with addresses and purposes. Where customer content and backups are stored — the datacenter is named as AWS without a region — as well as AI processing location and ownership are not established by the captured pages, and the contracting entity for services is stated to be a group company named in the contract.
Pricing transparency
Sanity
Free at $0 and Growth at $15 PER SEAT / MONTH are public with the billing period, unlimited locales and content types on every plan, viewer seats free, and overage rates stated for API requests ($1 PER 25K), CDN requests ($1 PER 250K), bandwidth ($0.30 PER 1GB), assets ($0.50 PER 1GB), documents ($299 FOR 50K IN TOTAL), embeddings and AI credits ($0.05 PER AI CREDIT), with SSO, the audit trail and the SLA named as the Enterprise plan. The Enterprise plan itself is CUSTOM PRICING, invoice payment and annual billing are Enterprise-only, and the terms reserve the right to change AI consumption rates at any time with immediate effect, alongside one-year auto-renewing terms with sixty days' non-renewal notice. We found no public information on the cost of the export after termination.
Storyblok
The self-service plans are priced with per-unit overages on the public page (seats at 15,00 €/month, extra locales at 20,00 €/month each, API requests at 10,00 €/month per 1M, traffic at 75,00 €/month for each 250GB, AI credits at 20,00 €/month per 200k), annual payment gives one month free, and the terms state a one-year default term with 30-day non-renewal notice and auto-renewal. Premium and Elite plans are quoted as "Custom", the FlowMotion tiers are contact sales, enterprise overages are billed at Order Form rates, and we found no public information on the cost of exporting or leaving the platform.
