The verdict in three sentences
WordPress remains the best cost-to-timeline ratio for a catalogue site under 150 pages with a team that must publish on its own. Headless (Next.js + CMS) is justified once performance, security and multi-channel become strategic, at a higher entry ticket and a need for developers. The 2026 tipping point sits around 200 pages and a target LCP under 1.5 s.
Cost compared in 2026
2026 orders of magnitude for a Berlin manufacturer (product catalogue site, EN/DE, quote forms, downloadable spec sheets).
| Item | WordPress | Headless (Next.js + CMS) |
|---|---|---|
| Design + integration | EUR 8,000 - 18,000 | EUR 15,000 - 35,000 |
| Hosting | EUR 20 - 60/mo | EUR 30 - 120/mo |
| Plugin / CMS licences | EUR 200 - 800/yr | EUR 0 - 2,500/yr |
| Monthly maintenance | EUR 300 - 800/mo | EUR 400 - 1,000/mo |
| Go-live time | 5 - 10 weeks | 8 - 16 weeks |
| Editorial autonomy | High | High (via CMS) |
WordPress wins on the initial ticket and timeline; headless catches up on long-term performance and security.
Performance and maintenance: where the difference lies
| Criterion | WordPress | Headless |
|---|---|---|
| Typical LCP (well optimised) | 1.8 - 3.0 s | 0.8 - 1.5 s |
| Mobile Lighthouse score | 60 - 85 | 90 - 99 |
| Attack surface | High (plugins) | Reduced |
| Security updates | Frequent, critical | Rare, controlled |
| Hiring profiles | Easy, abundant | Rarer, pricier |
| Scalability (traffic, pages) | Good up to ~200 pages | Excellent |
Headless often halves the LCP, which directly affects SEO and the conversion rate of quote requests.

Mini case study
Karim, marketing director at an aluminium joinery manufacturer in Berlin (120 product references), is undecided. WordPress quote: EUR 12,000 + EUR 500/mo. Headless quote: EUR 24,000 + EUR 700/mo. Over 3 years: WordPress = 12,000 + 18,000 = EUR 30,000; headless = 24,000 + 25,200 = EUR 49,200. But his current 3.2 s LCP drags his rankings; he estimates moving to 1.2 s would lift quote requests by 18 %, roughly 40 extra leads/year. At 4 % conversion and a EUR 6,000 average order, the annual gain exceeds EUR 9,000: headless pays back within 2 years.
FAQ
Is WordPress outdated in 2026? No. Well architected and lean, it remains relevant for most brochure and catalogue sites under 200 pages. The problem is not WordPress, it is plugin-bloated installs.
Is headless harder to maintain in-house? Content is managed just as simply through the CMS (Sanity, Strapi, Contentful). However, any technical change requires a developer, unlike WordPress where an integrator often suffices.
What is the real SEO impact? Performance (Core Web Vitals) is a ranking factor. Moving from a 3 s LCP to 1.2 s improves crawl, mobile ranking and conversion. Headless starts with a structural advantage.
At what volume does headless become obvious? Beyond 200 pages, with several languages and multi-channel needs (site + app + kiosks), headless becomes the rational choice. Below that, WordPress is often enough.
Can we migrate later? Yes, but a WordPress-to-headless migration costs 60-100 % of a new build. Better to decide up front based on your 5-year trajectory.
