The verdict in three sentences
Headless (a decoupled front plus a CMS like Sanity or Strapi) brings performance, security and multichannel flexibility, at a cost of EUR 12,000 to 30,000 and 6 to 12 weeks. It becomes profitable beyond a certain content and channel volume; below that, a monolithic CMS stays simpler and cheaper. For a Berlin company, the decision hinges on editorial volume, multichannel needs and performance requirements.
Monolithic vs headless: the comparison
The two architectures serve different needs. Here are the concrete differences in 2026.
| Criterion | Monolithic (e.g. WordPress) | Headless (Sanity/Strapi + Next.js) |
|---|---|---|
| Project cost | EUR 4,000 - 15,000 | EUR 12,000 - 30,000 |
| Timeline | 3 - 8 weeks | 6 - 12 weeks |
| Performance (LCP) | average | excellent |
| Security | high plugin surface | reduced surface |
| Multichannel (web, app, IoT) | limited | native via API |
| Editorial autonomy | high | high (dedicated interface) |
| Maintenance/year | EUR 1,500 - 3,000 | EUR 1,000 - 2,200 |
Headless shines when you distribute the same content across several channels or when performance is strategic. For a simple brochure site, monolithic is often enough.
License costs and break-even point
The CMS recurring cost depends on content volume, number of users and API bandwidth. Here are the 2026 orders of magnitude.
| Headless CMS | Indicative monthly cost | Best for |
|---|---|---|
| Strapi (self-hosted) | EUR 0 - 200 (hosting) | Full control, tight budget |
| Sanity | EUR 0 - 1,500/month | Structured content, teams |
| Contentful | EUR 300 - 1,500+/month | Enterprises, large volumes |
| Directus | EUR 0 - 250 (self-hosted) | Open source, data control |
Indicative break-even: headless pays off from 200 to 300 pages/entries or as soon as you feed 2 or more channels (site plus app, for example). Below that, the extra project cost isn't justified.
Mini case study
Julien, IT director at a software vendor in Berlin, manages 450 product pages feeding both the website and a mobile app. In monolithic, each piece of content was entered twice, tying up 0.5 FTE editorial (about EUR 20,000/year). In headless, content is entered once and distributed via API across both channels, removing the double entry. The EUR 24,000 migration pays for itself in 15 months from editorial savings alone, before even counting the performance and conversion gains.

FAQ
How much does a headless CMS migration cost in 2026?
Between EUR 12,000 and 30,000 depending on content volume and integrations, plus a CMS license of EUR 0 to 1,500/month depending on the solution and volume.
Is headless always faster?
Generally yes, because the front is optimized and decoupled from the back office. The LCP gain is clear against a plugin-heavy monolithic CMS.
Do you need developers to publish content in headless?
No. Editors use a dedicated interface (Sanity Studio, Strapi admin). Only the initial setup requires developers.
When does headless become profitable?
From 200 to 300 content entries or as soon as you distribute across 2 or more channels. Below that, a monolithic CMS stays more economical.
Which headless solution should I choose?
Strapi or Directus to control costs and data, Sanity for structured team content, Contentful for very large enterprise volumes.
