Best Headless CMS Platforms for Developers in 2026: Contentful vs Sanity vs Strapi

At a Glance

CMS	Hosting Model	Free Tier?	Entry Paid Price	Primary APIs
Contentful	Fully managed SaaS only	Yes (Free, forever)	$300/month (Lite)	REST (Content Delivery/Management API) and GraphQL
Sanity	Managed (Content Lake) with open-source Studio you can self-host as a UI	Yes (Free, forever)	$15/seat/month (Growth)	GROQ (native query language) plus a GraphQL API
Strapi	Self-hosted (MIT-licensed, free) or Strapi Cloud (managed)	Yes — Community Edition is free and open-source; Cloud has no permanent free tier	$35/month (Cloud Starter) or $45/month (self-hosted Growth)	REST by default, with an official GraphQL plugin

These three aren’t really competing on the same axis. Contentful and Sanity are managed, API-first content platforms you rent; Strapi is open-source software you can run yourself for free, with a managed Cloud option if you don’t want to. If “self-hosted” or “no vendor lock-in” matters to your team, that alone should narrow the field before price does.

What These Platforms Are

A headless CMS separates content storage and editing from presentation, serving content to any frontend — a Next.js site, a mobile app, a kiosk — through an API rather than server-rendered templates. Contentful and Sanity are both commercial SaaS platforms: you don’t run any servers, you just model content and query it. Strapi is different in kind, not just in price: it’s an open-source Node.js application distributed under the MIT license, which you can self-host on your own infrastructure at zero license cost, or run on Strapi’s own managed Cloud if you’d rather not operate it yourself.

Pricing Breakdown

Platform	Tier	Price	Key Limits
Contentful	Free	$0 forever	10 users, 2 locales, 100K API calls/month, 50GB CDN bandwidth/month, 1 Starter Space (25 content types, 2 environments, 10,000 records)
	Lite	$300/month	20 users, 3 locales, 1M API calls/month, 100GB bandwidth/month; a second “Lite Space” costs an additional $850/month
	Enterprise	Custom quote	Unlimited API calls, custom users/spaces, 24/7 support, up to 99.99% uptime SLA
Sanity	Free	$0 forever	Up to 20 seats, 2 public datasets, 10k documents, 1M CDN API requests/month, 100GB bandwidth
	Growth	$15/seat/month	Up to 50 seats, private datasets, 25k documents; add-ons include Dedicated Support ($799/month) and extra datasets ($999/dataset/month)
	Enterprise	Custom quote	Custom seats/datasets, SAML SSO, custom roles, uptime SLA, invoice billing
Strapi	Community Edition (self-hosted)	$0, MIT license	Unlimited users; RBAC included; no audit logs, review workflows, or SSO
	Cloud Starter	$35/month	100k API requests/month, 50GB storage, 50GB bandwidth, project sleeps when idle, no backups
	Cloud Business	$450/month	10M API requests/month, 1,000GB storage/bandwidth, daily backups, 99.9% uptime SLA, priority support

Strapi also sells a self-hosted Growth plan at $45/month (including 3 users) for teams that want enterprise features like Live Preview and content-release tooling without moving to Strapi Cloud, with add-ons for SSO ($150/month plus $50/user/month) and AI credits. All three vendors charge overage fees once you exceed a tier’s included usage: Contentful at $5 per extra 1M API calls, Sanity at $1 per extra 250k CDN requests, and Strapi at $1.50 per extra 25k API requests.

Pros and Cons

Contentful

• Pros: Mature structured-content model with 2 free environments and a generous 100K-call free tier; both REST and GraphQL content APIs are first-class, well-documented options.
• Pros: Enterprise tier adds Personalization, Studio, and AI Actions add-ons for teams that want a broader content platform, not just an API.
• Cons: The jump from Free to Lite is steep — $300/month — with a second content “Space” costing a further $850/month, which is a real cliff for growing teams.
• Cons: No self-hosting option at any price; you’re locked into Contentful’s infrastructure and SLAs.

Sanity

• Pros: GROQ, Sanity’s native query language, gives developers a genuinely different (and widely praised) way to shape complex, relational content queries that REST-only CMSs struggle with; a GraphQL API is also available.
• Pros: Per-seat pricing ($15/seat on Growth) is more predictable for small teams than Contentful’s flat per-plan jump, and the free tier’s 20 seats is generous.
• Cons: The Sanity Studio editing UI is open-source and can be self-hosted, but the underlying Content Lake (where data actually lives) is managed-only — there’s no fully self-hosted path.
• Cons: Private datasets, review tooling, and SSO are gated behind Growth and Enterprise respectively, and extra datasets are expensive at $999/month each on Growth.

Strapi

• Pros: The only one of the three that’s genuinely free to self-host at any scale under an MIT license — no seat caps, no usage meters, full control of your data and infrastructure.
• Pros: Ships REST by default with an official GraphQL plugin, so teams aren’t locked into one query paradigm.
• Cons: Community Edition has no audit logs, review workflows, or SSO out of the box — those require either the paid Growth/Enterprise self-hosted tiers or Strapi Cloud.
• Cons: Self-hosting means you own uptime, scaling, and security patching yourself; Strapi Cloud’s entry Starter tier has no backups and the project “sleeps when idle,” which isn’t production-ready for most sites.

Who Each Platform Is a Good Fit For — and Who Should Look Elsewhere

Contentful suits teams that want a battle-tested, fully managed platform and can either stay comfortably within the Free tier’s limits or justify enterprise-level spend — the Lite tier’s $300/month floor makes it an awkward middle option for small teams scaling past free-tier usage. Sanity is a strong fit for developers who want a more expressive query layer than REST alone and whose team size maps cleanly onto per-seat pricing. Strapi is the right call for teams that want to self-host, avoid recurring API-call fees entirely, or need full control over their data residency and infrastructure — and the wrong call for teams that don’t want to own server operations and aren’t ready to pay for Strapi Cloud’s production-grade (Business-tier) reliability.

Bottom Line

Pick Strapi if self-hosting or open-source licensing is a requirement, not a preference. Pick Sanity if your content model is complex and relational and your team will benefit from GROQ’s query power. Pick Contentful if you want the most established managed platform and your usage (or budget) clears the Free-to-Lite jump comfortably. All three remain actively developed, officially documented, and genuinely API-first — the real decision is hosting model and pricing shape, not capability.

Frequently Asked Questions

Can I self-host Contentful or Sanity? No. Contentful is fully managed SaaS with no self-hosted option. Sanity’s Studio editing interface is open-source and can be self-hosted, but its Content Lake data store is managed-only.

Is Strapi really free? Yes — Strapi Community Edition is MIT-licensed and free to self-host with unlimited users, though you pay for your own hosting infrastructure and lose enterprise features like audit logs and SSO unless you upgrade to a paid self-hosted tier or Strapi Cloud.

Does Sanity support GraphQL, or only its own query language? Both. GROQ is Sanity’s native and most commonly used query language, but a GraphQL API is also officially available.

Which platform is cheapest for a small project? On a strict free-tier basis, all three offer a permanent free plan, but Strapi’s free Community Edition has no usage meter at all (only your own hosting costs), while Contentful and Sanity’s free tiers cap API calls, records, and bandwidth.

Do any of these charge for exceeding usage limits? Yes. Contentful charges $5 per additional 1M API calls; Sanity charges $1 per additional 250k CDN API requests on Growth; Strapi Cloud charges $1.50 per additional 25k API requests.
