Sanity Free with 20 seats is the most generous free CMS tier in the market — Contentful and Hygraph cap at 5-10.
Growth at $15/seat/mo is reasonable until you hit the add-on costs: SAML SSO is $1,399/mo and extra datasets are $999/mo each. The real expense is API overages at scale — $1/25K non-CDN requests adds up fast for headless CMS patterns.
Document limits (10K free, 25K Growth) can also force expensive upgrades for content-rich sites.

SAML SSO add-on costs $1,399/mo on Growth — nearly 100x the base seat price
Extra datasets cost $999/dataset/mo — expensive for multi-brand or staging setups
API request overages at $1/25K (non-CDN) can spike with server-side rendering patterns
Document limit of 25K on Growth requires a $299/mo add-on to expand to 50K total
Developer teams wanting a customizable structured content platform
Companies needing real-time collaboration on content
Projects requiring flexible content modeling with GROQ query language
Teams that want generous free-tier seats for editorial staff
startup
Free plan with 20 seats and 10K documents handles most early-stage content needs. Growth when you need private datasets or more than 2 roles.
enterprise
Enterprise for SSO, custom datasets, and negotiated API limits. Budget separately for add-ons — Growth plan add-ons (SSO + support + datasets) can easily exceed $3K/mo.
Contentful starts at $300/mo with far fewer free seats — 10-20x more expensive at the Growth tier. Hygraph Professional is $299/mo, also more expensive than Sanity Growth. Strapi is open-source and self-hosted (free) but requires DevOps investment. Sanity wins on free-tier generosity and real-time collaboration; Contentful wins on enterprise ecosystem maturity.
