Your website isn't a tech project. It's a business lever.
So every choice we make — framework, CMS, hosting — answers one question: does it help your business?
A fast site is a site that pays off.
Each extra second of loading costs 7% of conversions (source: Portent). An Astro site loads in under a second. The maths is simple.
Speed = conversion
A visitor who waits leaves. A site that responds instantly keeps them — and converts them.
Speed = visibility
Google ranks fast sites higher. A site built to load fast is, by construction, easier to find.
Five things no one else does.
Prices visible before contact
The whole pricing grid is public. The configurator gives a precise amount. You know what it costs before you ever pick up the phone.
The 95 Guarantee
Every site we deliver holds a 95+ performance score on mobile. Not a promise with an escape hatch — our standard, measured at delivery.
You own everything
Open-source stack, code in your own Git repo, €0/mo of infrastructure. No SaaS subscription, no lock-in. Any Astro developer can pick it up.
An SEO team that codes
SM4B has done search optimisation since 2012. We don't "think" about findability after the fact — it's baked into how we build, from the markup up.
The site proves the service
astro4b.com is itself an Astro site with Decap CMS. The configurator you just used is the proof. What you see is exactly what we ship.
Astro vs. a classic CMS.
WordPress was perfect in 2010. Today it's a permanent compromise between plugins, security and speed. We respect it — we just chose specialisation.
A classic CMS (e.g. WordPress)
Astro
And Next.js? Powerful for complex apps (SaaS, dashboards). Oversized and slower for a showcase site or a blog.
Three tools. €0 per month.
The framework
Ships almost no JavaScript. Static or hybrid rendering. The fastest framework for content sites.
The editing interface
Visual, in the browser, no database. Your content lives in your Git repo — not on someone else's server.
The hosting
Global CDN, automatic HTTPS, deploy in 30 seconds. Free up to 500 builds a month.
Monthly infrastructure cost: €0. No server to maintain. No CMS subscription. No licence. You own all of your code.
