The verdict in three sentences
WordPress stays unbeatable on time-to-market and content editing, but pays its debt in security and performance. Jamstack (decoupled front + headless CMS) costs more to build but delivers a superior LCP and a near-zero attack surface. For a high-traffic or speed-critical B2B site, Jamstack recoups its premium in 24 to 30 months.
Build and operating cost
Entry price does not tell the whole story: recurring costs widen the gap over 3 years.
| Item | WordPress | Jamstack / headless |
|---|---|---|
| Initial build | 8,000 - 15,000 EUR | 12,000 - 22,000 EUR |
| Monthly hosting | 30 EUR/mo | 20 EUR/mo |
| Security maintenance | 80 - 150 EUR/mo | 20 - 40 EUR/mo |
| Plugin updates | Recurring, risky | Not applicable |
| Delivery time | 6 - 10 weeks | 7 - 11 weeks |
2026 orders of magnitude show a Jamstack build 30 to 45% more expensive, but operation 40 to 60% cheaper.
Performance and security compared
This is where Jamstack takes the decisive edge for a B2B site chasing conversion and SEO.
| Criterion | WordPress | Jamstack | Gap |
|---|---|---|---|
| Median LCP | 2.8 s | 1.6 s | -40% |
| Lighthouse perf score | 65 - 80 | 90 - 99 | +20 pts |
| Attack surface | High (plugins) | Minimal (static) | Sharp reduction |
| Traffic spikes | Server strain | Unlimited CDN | Robust |
| Content editing | Instant, WYSIWYG | Via headless CMS | WP more flexible |
An LCP dropping from 2.8 s to 1.6 s lifts B2B conversion by 7 to 12% per 2026 studies.
Mini case study
Sarah, COO of a 40-employee B2B industrial firm in Amsterdam, is weighing a redesign of her site that generates 1,800 leads a year. WordPress: 11,000 EUR build + 1,500 EUR/yr to run. Jamstack: 16,000 EUR + 600 EUR/yr. Over 3 years the gap falls to about 2,300 EUR. But the LCP gain lifts her lead conversion from 1,800 to 2,000 a year; at 250 EUR margin per lead, that is 50,000 EUR of extra annual margin. The Jamstack choice becomes obvious.

FAQ
Is Jamstack always faster?
In nearly every case yes, thanks to static pre-rendering served from a CDN. The LCP gap sits around 40% against a standard, unoptimized WordPress.
Can we keep simple content editing on Jamstack?
Yes, a headless CMS like Sanity or Strapi offers a comfortable editing interface decoupled from the front. Writers see no difference.
Is WordPress less secure?
Not by nature, but its plugin ecosystem multiplies vulnerabilities. Static Jamstack drastically reduces the attack surface.
Which fits a small brochure site?
If content changes often and traffic is modest, WordPress stays very competitive. Jamstack earns its place on performance, SEO, or high-traffic stakes.
Is delivery time longer?
Barely: 7 to 11 weeks for Jamstack versus 6 to 10 for WordPress. The difference is the initial architecture setup.
