What the models said for it

Verbatim evidence the judge attached to positive labels.

“Choose Sanity when your company treats content as reusable, structured data rather than primarily as website pages.” GPT-5.6 Sol · Marketing CMS · direct prompt · alternative

“Sanity with a custom frontend. It supports visual editing, but that experience requires frontend integration.” GPT-6 Astra · Marketing CMS · paraphrase prompt · alternative

“Sanity typically costs 60–80% less at comparable functionality, with Growth starting at $15/seat/month” Claude Opus 5 · Marketing CMS · direct prompt · alternative

“Contentful, Sanity, or Storyblok if you have a developer-led, headless architecture” Perplexity Sonar Pro · Marketing CMS · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Contentful, Sanity, Storyblok, Strapi and similar systems can be excellent. But “headless” is not automatically more modern or better.” GPT-5.6 Sol · Marketing CMS · negative prompt · soft negative

“the trap here is that a marketing site is not the use case headless was built for” Claude Opus 5 · Marketing CMS · paraphrase prompt · soft negative

“Do not adopt a headless CMS unless you have dedicated, in-house developers” Gemini 3.1 Pro · Marketing CMS · negative prompt · soft negative

“can be a poor fit if your marketing team needs to publish independently” Perplexity Sonar Pro · Marketing CMS · negative prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Sanity, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
