Sanity

Sanity is a headless CMS: it manages content without imposing a website. Text, images and references are stored as structured data, then delivered through an API to a website, an app or an AI agent. Our custom offer pairs Astro and Sanity for projects that go beyond what a visual CMS can do. This page explains when that choice makes sense compared with Webflow.

What is Sanity?

Sanity describes itself as a content operating system. It combines three building blocks.

• Sanity Studio: the editing interface, open source and built in React, which developers configure in code.
• Content Lake: the hosted database that stores content in real time.
• API, CDN and MCP server: content delivery to websites, apps and AI assistants.

The content schema is written in code. Every document type, field and validation rule is versioned with the project. Teams edit together in real time, with preview and visual editing on the site.

Sanity pricing

The prices below were taken from the official pricing page on 23 October 2026, in US dollars, per month.

The Growth plan accepts add-ons: increased quota at $299 a month, an extra dataset at $999 a month and dedicated support at $799 a month. Beyond the included quotas, usage is billed on consumption.

Sanity or Webflow for a B2B website?

They answer different needs. Webflow combines design, CMS and hosting in one visual tool. The marketing team edits its pages without a developer. Sanity only manages content. The site has to be built separately, in Astro or Next.js, then hosted.

• Webflow suits most B2B websites: company pages, blog, case studies, industry pages and multilingual content.
• Sanity makes sense when the same content feeds several channels, when the data model is complex or when the site is part of a software product.

Webflow is moving in this direction too with Source, which plugs into Next.js or Astro stacks, as our article on Source by Webflow explains.

Our review of Sanity

Sanity is one of the most mature headless CMSs: content model in code, real-time collaborative editing and openness to AI agents. In return, it requires a development team for the site and its maintenance. We keep it for projects where that flexibility brings real value.

Strengths

• A fully customisable, versioned content model.
• Real-time collaborative editing with preview.
• A generous free plan, up to 20 users.
• An MCP server and a Content Agent for working with AI.

Limits

• A website to build and host separately.
• Reliance on developers to evolve the models.
• Paid add-ons that climb quickly beyond the quotas.
