The verdict in three sentences
A headless CMS pays off when several teams publish on the same website and the legacy WordPress piles up plugins, formatting conflicts and email approvals. The 2026 budget for a headless corporate website is 20,000 to 60,000 EUR (about 22,000 to 66,000 USD), with a recurring cost that depends on choosing Sanity (SaaS, 0 to 949 USD a month depending on plan and usage) or Strapi (self-hosted, 30 to 150 EUR a month of infrastructure). Well scoped, the project halves publishing time thanks to a structured editorial workflow and reusable content.
Classic WordPress, headless WordPress, Strapi or Sanity
The digital lead of a mid-sized company where six teams (communications, HR, product marketing, investor relations, subsidiaries, legal) publish on one website knows the symptoms: broken pages after a plugin update, overly broad permissions, no trace of who approved what. Here are the four realistic options in 2026.
| Criterion | Classic WordPress | Headless WordPress | Strapi | Sanity |
|---|---|---|---|---|
| Build cost | 12,000 to 30,000 EUR | 22,000 to 50,000 EUR | 20,000 to 55,000 EUR | 25,000 to 60,000 EUR |
| Recurring cost | 50 to 200 EUR/month + plugin licences | 100 to 300 EUR/month (two hosting stacks) | 30 to 150 EUR/month hosting | 0 to 949 USD/month by plan |
| Approval workflow | Third-party plugin, fragile | Third-party plugin | Native in Enterprise edition, otherwise custom | Native and customisable |
| Simultaneous editing | No (locking) | No | Limited | Yes, real time |
| Performance (Core Web Vitals) | Depends on theme | Excellent | Excellent | Excellent |
| Vendor dependency | Low | Low | Low (open source) | Medium (SaaS) |
| Team onboarding | Familiar | Familiar back office | 1 to 2 days of training | 1 to 2 days of training |
Sanity suits organisations that want a rich editorial studio without running servers. Strapi suits those that require hosting in a specific region or on their own cloud, often for data residency or IT policy reasons.
Where the headless budget goes
| Item | 2026 range | Comment |
|---|---|---|
| Audit of the existing site and content modelling | 3,000 to 8,000 EUR | The most structuring step |
| Design system and mockups | 5,000 to 12,000 EUR | Components reused by all 6 teams |
| Next.js front end | 6,000 to 20,000 EUR | Static and incremental rendering |
| CMS configuration, roles, workflow | 3,000 to 8,000 EUR | Draft, review, approval, publish |
| WordPress content migration | 2,000 to 8,000 EUR | Scripts plus manual clean-up |
| Training and editorial documentation | 1,000 to 4,000 EUR | One session per team |
| Total | 20,000 to 60,000 EUR | 3 to 5 month timeline |
Content modelling is the item you must never squeeze: a poorly designed model reproduces the WordPress mess in a more expensive tool. New York agency rates typically sit 20 to 40% above these Paris figures (2026 order of magnitude).
Pitfalls to avoid
First pitfall: preview. Without live preview, editors publish blind and come back to IT. Require a preview mode in the specification. Second pitfall: Sanity's usage-based billing, which can climb if APIs are called without caching. A well-built front end, with static rendering and revalidation, keeps most sites on free or mid-tier plans. Third pitfall: forgetting forms, search and multilingual support, which the CMS does not provide and must be budgeted separately, at 2,000 to 6,000 EUR depending on scope.
Mini case study
Camille, digital lead of a services company in Paris, coordinates 6 teams publishing 40 pieces of content a month. On WordPress, each publication takes on average 3 hours between writing, formatting, corrections and email approvals, or 120 hours a month. After migrating to Sanity, with predefined components and a built-in workflow, this drops to 1.5 hours, saving 60 hours a month. At a loaded hourly cost of 55 EUR, the gain reaches 3,300 EUR a month. For a 42,000 EUR project and a 99 USD monthly licence, payback comes in about 13 months, before counting fewer technical incidents. A New York team with higher hourly costs reaches payback even faster.

FAQ
Is Strapi really free?
The community edition is open source and free, but hosting, backups and updates cost 30 to 150 EUR a month, plus 1 to 2 days of maintenance per quarter. Some advanced features, such as the native review workflow, belong to the paid edition.
Can we keep WordPress as the back office?
Yes, headless WordPress reassures teams used to the tool. It does keep the plugin dependency and requires two hosting stacks, at 100 to 300 EUR a month.
Is a headless website good for SEO?
Yes if it is server-rendered or static, as with Next.js. Well-built headless sites often score above 90 on mobile Lighthouse.
How long does migrating 800 WordPress pages take?
Allow 3 to 6 weeks depending on existing content quality: about 70% migrates by script and 30% needs manual rework.
Where is the data hosted?
With Strapi, you choose the host and region. With Sanity, check the storage region and the data processing terms available on your plan.
