Straight answers about Sanity CMS to most common questions we get
Sanity CMS is an open-source platform used to manage structured content. It features Sanity Studio, a customizable editing environment that supports real-time collaboration and content management across multiple channels.

Sanity is highly adaptable and supports a range of programming languages and frameworks used in web development, including JavaScript, React, Vue.js, and notably Next.js.
Sanity CMS is more flexible and developer-friendly than WordPress. It uses a headless architecture that separates content from presentation, making it faster, more scalable, and easier to integrate with modern frameworks like Next.js and React. WordPress is easier for quick setup, but Sanity is better for teams that need performance, custom workflows, and structured content.
Many global brands use Sanity CMS, including Figma, National Geographic, Sonos, and Nike. These companies rely on Sanity for its flexibility, real-time collaboration, and ability to scale across multiple teams and websites. Sanity is also used by startups and agencies that need a fast, customizable content platform.
The timeline depends on three factors: the complexity of the content model, the level of Sanity Studio customisation your editorial team needs, and whether we’re doing a migration or a new build. As a Sanity CMS agency with dozens of production deployments, we’ve seen both ends of the range.
A straightforward Sanity Content Management System build runs about 6-8 weeks. A migration from WordPress or Contentful, including content transformation and QA, typically takes 10–14 weeks. We scope this in detail before we start, so the estimate reflects what we’ll actually build.
Think headless CMS are not customizable? We disproved this using Sanity
Sanity encourage to customize almost everything. Any Sanity module can be rewritten. This makes it possible to have your own combination of standard and custom components in your application.
