Sanity vs Storyblok

Storyblok's documentation describes three kinds of block. A content type block is a story, such as a page or an article. A nestable block, such as a hero or a text section, lives inside another block. A universal block can be either. Every blank space ships with a page content type, and a page's body is typically a field of nested blocks.

That makes the page the natural unit. The draft API attaches an _editable marker to every block, which is what lets the visual editor select a block in the preview. According to the same docs, a block's _uid is unique only within its own story. A nested block belongs to the page that holds it.

Sanity starts from documents. Its page-building guide describes a page builder as an array of objects or references, and states the trade in two lines. Objects are easier to query but trapped within the document. References can be reused between documents, and your queries must resolve them.

A Sanity vs Storyblok comparison that stops at visual editing against structured content misses this. Each lets you nest content inside a page, and each lets you point at shared content instead. What differs is the default each one hands you, and what the second option costs.

Storyblok's own tutorial on global components sets out the steps. Create a content type for shared content and a folder restricted to it. Add a story there for the shared piece, such as a newsletter panel. Then create a nestable block with a References field pointing at that folder, and place it wherever the panel should appear.

By default the API returns only the referenced story's ID. To get its content, each request names the parent block and the field, as in resolve_relations=global_reference.reference. The live preview bridge needs the same list, or live updates reach the page with the reference unresolved.

Storyblok's technical limits cap that at 50 resolved stories per request. Past 50, the response lists the remaining IDs for your code to fetch in another request, which Storyblok's JavaScript SDKs do automatically. The tutorial also advises against the pattern for headers and footers: load those once and reuse them, rather than resolving them on every page.

In Sanity, the shared panel is a document, and a page's array holds a reference to it. A GROQ projection follows the reference with the -> operator inside the same query, so the page and the panel arrive together. Sanity's technical limits put no count on references followed; the ceilings are a minute of execution time and the working set.

Sanity also guards the shared piece. A strong reference, the default, blocks deleting a document others point to. Both can say where a shared block is used: Storyblok through a story-list filter, Sanity through an incoming references pane.

Reuse across pages is affordable on both. Reuse across sites is where the self-serve plans stop. Storyblok's References field links to stories in the same space, and its spaces documentation says linking between spaces is not supported. Every self-serve plan includes one space, and each further space is a separate subscription.

Storyblok's own advice for three websites with closely related content is one space with a folder per domain, so blocks can be shared. It names the drawback: editors switch the preview environment by hand, and Growth allows six preview URLs. Sharing block schemas between spaces takes the Shared Components app, which requires Premium, and distributing content across spaces is on Elite.

Sanity draws the same line one level down. References work inside one dataset. Cross-dataset references are available on certain Enterprise plans, and Sanity's pricing FAQ says content cannot be referenced across projects at all. Free and Growth each include two datasets, so a staging copy fits, but a second brand sharing content has to share a dataset.

What Sanity adds is a way to preview several sites from one place. A single Presentation tool can load more than one front end, so three sites on one dataset can each be previewed from the same Studio without editors changing a setting.

Priced for six editors across three related sites, Sanity Growth is $90 a month on one dataset and Storyblok Growth is $114 in one shared space. Splitting the sites into three Storyblok spaces costs from $45 on Starter to $297 on Growth, but the shared pieces then become copies kept in step by hand or by script.

Both vendors limit how complex a content model can get, and they count different things. Storyblok counts block schemas: 200 per space on Starter and 600 on Growth and Growth Plus, unlimited on Premium and Elite. It also caps a story's API response at 5MB on every plan, which bounds how much one page can hold.

Sanity counts unique attributes, meaning every distinct combination of path and data type that holds content in a dataset. Free allows 2,000 and Growth 10,000. A single document may hold 1,000 on either plan, nesting stops at 20 levels, and one document can be as large as 32MB.

The two counts punish different habits. On Storyblok, a design system with hundreds of block variants runs into the schema cap, while using the same blocks on thousands of pages costs nothing extra. On Sanity, repetition is free too, because a path counts once however often it is used. New paths are what cost, and deep or recursive nesting creates them quickly.

Sanity's attribute guide is explicit about page builders. It recommends arrays of objects over rich text full of custom objects, and warns against structures that can contain themselves. It also says Enterprise does not raise the 10,000 limit, while the pricing table lists Enterprise as custom.

Entries are counted too: 25,000 stories on Storyblok Growth and 100,000 on Growth Plus, against 25,000 Sanity documents on Growth, drafts included, or 50,000 with the $299 add-on. For 30,000 entries and five editors, that is $349 a month on Storyblok against $374 on Sanity, though a story and a document are not the same unit.

Storyblok's visual editor is where its editors work by default. Clicking a block in the preview opens it for editing, blocks can be added, moved and duplicated in place, and admins can save presets, which are blocks pre-filled with content. The form view is one click away. For a marketing team that builds pages every week, this is the product.

It asks things of the front end. Every draft block carries an _editable marker your components render as data attributes. The preview must be served over HTTPS, localhost included, and your content security policy must let Storyblok frame it. The bridge reloads the page on save unless you wire up live input events.

Sanity's editors start in forms, and the Presentation tool adds the page. Click-to-edit overlays come from stega encoding, which hides source details inside strings as invisible characters. Sanity's docs warn that those characters can break string comparisons, URL construction and date parsing, so front-end code has to clean values before using them in logic.

Page building in Presentation works on arrays of objects. Drag and drop needs a recent visual editing package, which in turn needs React 19.2 or later, and Sanity says it does not work on touch devices. On the Next.js App Router, Sanity's own performance guide notes that each edit in draft mode re-renders the whole route.

Neither editor is automatically the easier one for non-developers. In an r/Nuxt thread from March 2024, a developer who had built a friend's site on Storyblok said the idea of components was too hard for a non-developer to follow. A freelancer in r/webdev in October 2024 believed Sanity had no drag and drop, which Sanity has since documented.

Of these two, Storyblok alone prints an uptime figure on a self-serve plan: 97% on Growth and Growth Plus. Read the terms before relying on it. The clause carrying a refund credit, in terms updated 7 April 2025, names 99.9% for Premium and 99.99% for Elite, measured as an annual average.

The self-service section then replaces that clause with "best possible availability" as the pricing page describes it. As a figure, 97% of a 30-day month allows 21.6 hours of downtime, and 97% of a year allows nearly 11 days. Sanity publishes no uptime figure below Enterprise, so neither self-serve plan comes with one you can claim against.

Backups follow the same pattern. Storyblok's self-service terms say it creates no backups of customer data, and Sanity lists backups only on Enterprise. On either self-serve plan, the export you schedule is the only backup you have.

Acceptable use deserves a paragraph of its own. In October 2025, a poster in r/nextjs described a cannabis education site that had confirmed with Storyblok that its content was allowed. Months into the build, they wrote, it was moved to Enterprise-only terms: a plan of about 350 euros a month became a quote of 1,980 euros on a three-year commitment.

That is one customer's account, and I could not verify it beyond the thread. Storyblok's published acceptable-use clause names no industries, and Sanity's Growth terms let it suspend access for any reason in its reasonable discretion. If your content is anything a legal team might reclassify, get written approval into the contract on either platform.
