Sanity CMS is a headless content platform: your content lives in a hosted, structured database (Sanity calls it the Content Lake), and your website, app, or any other channel pulls from it through an API. We build marketing sites for a living, mostly on Webflow, and we get asked about Sanity a lot. So here is the honest version, verdict first: Sanity is a genuinely excellent tool for the right project and an expensive detour for the wrong one. This post covers what it does, what it costs as of 2026, and the exact line where we would pick it over Webflow.
Should you use Sanity CMS? The short answer
Use Sanity CMS when your content needs to live in more than one place: a Next.js site plus a mobile app, a docs portal, a product UI, or dozens of localized variants. Skip it when you need a 20 page marketing site, because a visual platform like Webflow ships that faster, cheaper, and without a developer on retainer. Here is the honest matrix:
| What you need | Sanity | Webflow CMS |
|---|---|---|
| Content reused across site, app, and other channels | ✅ | ❌ |
| Query content like a database (GROQ) | ✅ | ❌ |
| Real-time collaborative editing | ✅ | ❌ |
| Design, CMS, and hosting in one tool, no code | ❌ | ✅ |
| Marketing site live in weeks without a dev team | ❌ | ✅ |
| Custom editorial workflows and roles | ✅ | 🟡 |
If the left column of wins describes your roadmap, keep reading. If the right column does, you probably want a Webflow or WordPress build and your budget back.
What makes Sanity different
Sanity, often written as Sanity io after its domain, competes with Contentful, Strapi, and Storyblok in the headless space. If the term is new to you, start with our explainer on what a headless CMS is. Four things separate Sanity from the pack.
Structured content, not pages
In Sanity you do not create pages. You define document types in code: an author, a product, a case study, each with typed fields. Content becomes data that any frontend can assemble however it wants. This is the core trade: more upfront modeling work in exchange for content you can reuse everywhere without copy-pasting.
GROQ, a query language for content
Most CMS APIs hand you fixed endpoints. Sanity gives you GROQ, a query language that lets you fetch exactly the fields you need, filter, join references, and reshape the response in one request. For developers it feels closer to querying a database than calling a CMS. GraphQL is also available if your team prefers it.
Real-time collaboration
Multiple editors can work in the same document simultaneously and watch each other's changes appear live, the way Google Docs behaves. For content teams that have suffered through "who overwrote my draft" in older systems, this alone is a selling point.
Sanity Studio, an editing UI you own
The editing interface, Sanity Studio, is an open source React application. You configure it in code, extend it with custom inputs and previews, and deploy it free on Sanity's hosting or anywhere else. That makes the editor experience fully customizable, and it also means every change to it goes through a developer. That is the recurring theme with Sanity: enormous flexibility, always priced in engineering hours.
Sanity pricing: what you actually pay
Numbers below are from the official Sanity pricing page as of August 2026. The subscription is only part of the cost, so read the overage notes too.
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Up to 20 seats, 10k documents, 2 datasets, 100 GB assets and bandwidth per month |
| Growth | $15 per seat per month | Up to 50 seats, 25k documents, 5 permission roles, comments, scheduled drafts |
| Enterprise | Custom | SSO, custom roles, audit trail and History API, uptime SLA, dedicated support |
The free tier is generous and real: a small team can run a production site on it. Past that, Sanity is usage based. Extra API requests run $1 per 25k, bandwidth overage is $0.30 per GB, and asset storage overage is $0.50 per GB. A high-traffic site that queries the API directly instead of through the CDN, or one that serves heavy images from Sanity, can rack up meaningful overages. Budget for the developer time too: unlike an all-in-one platform, the Sanity fee buys you the content backend only. The frontend, hosting, and every Studio customization are separate line items.
Sanity with Next.js, or just Webflow?
Sanity's natural partner is Next.js. The pairing gives you GROQ-powered data fetching, live preview of drafts inside your real frontend, and full control over rendering and performance. It is the stack we would reach for when a client needs an app-like site: a product with docs, a marketplace, a content operation publishing to web and mobile from one source, or a site whose pages are assembled from structured data rather than designed one by one.
For a typical marketing site, the calculus flips. A brochure site with a blog, some landing pages, and a careers page does not need multi-channel content or a query language. It needs great design, fast pages, and a CMS a marketer can drive alone. Webflow does all of that in one subscription, and changes ship without a deploy pipeline. We have built both stacks, and our Webflow development work consistently gets marketing teams live in a fraction of the time a custom Next.js build takes, at a fraction of the engineering cost.
The honest test: count your channels and count your developers. Two or more content channels and an in-house engineering team, choose Sanity CMS with Next.js. One website and a marketing team, choose Webflow, and put the savings into content. If you are unsure which side of the line your project falls on, our website development team scopes both stacks and will tell you plainly when the cheaper option is the right one.
Frequently asked questions
Is Sanity CMS free?
Yes, Sanity has a permanently free tier that includes up to 20 user seats, 10k documents, 2 datasets, and 100 GB of assets and bandwidth per month. It is enough to run a small production site. Paid plans start at $15 per seat per month on Growth, and usage beyond the included quotas is billed as overage.
Is Sanity a headless CMS?
Yes. Sanity is a headless CMS: it stores structured content in a hosted backend called the Content Lake and delivers it through APIs, without dictating how your frontend looks. You query content with GROQ or GraphQL and render it with any framework, most commonly Next.js. The editing interface, Sanity Studio, is a customizable React app.
What is the difference between Sanity and Webflow CMS?
Sanity is a headless content backend: developers model content in code and build the frontend separately, which suits multi-channel and app-like projects. Webflow CMS is part of an all-in-one visual platform where design, content, and hosting live together, which suits marketing sites. Sanity offers more flexibility; Webflow ships a website with far less engineering.
Do I need a developer to use Sanity?
To set it up, yes. Content schemas, the Studio configuration, and the frontend that renders your content are all defined in code, so launching with Sanity is a development project. Day-to-day editing afterwards is developer-free: writers work in Sanity Studio, which is a clean, real-time editing interface once it has been configured.
