Astro.js Agency Switzerland: Ultra-Fast Websites with Lighthouse 100/100

loaded is Switzerland's specialised Astro.js agency. We build websites that load in under 0.5 seconds, rank at the top on Google and ChatGPT, and save CHF 13,700 over 5 years compared to WordPress. From CHF 3,490.

The Problem

Why most Swiss business websites are too slow, too expensive, and invisible

Here is the hard truth about Swiss SME websites in 2026: the average site loads in 3.8 seconds, scores 45/100 on Lighthouse, and is completely invisible to AI assistants. For WordPress sites, it gets worse. Every installed plugin adds JavaScript bloat. Theme frameworks load 200–400 KB of unused code. Security patches are a constant headache — 90% of all hacked websites worldwide run on WordPress. And the ongoing costs? Hosting from CHF 30/month, premium plugins CHF 200–500/year, maintenance and updates CHF 100–300/month. Over 5 years, that adds up to CHF 15,000–25,000 — just for infrastructure, not counting redesigns. Webflow and Squarespace only partially solve the problem. Load times are better than WordPress but far from optimal. Add vendor lock-in, rising subscription prices, and limited control over SEO details. But the biggest problem is something else entirely: AI visibility. ChatGPT, Perplexity, Claude, and Google AI Overviews preferentially recommend websites with fast load times, clean HTML, and structured data. Template-based websites with bloated code are systematically disadvantaged. This means every day with a slow, poorly structured website costs you potential customers — on Google and with the new generation of AI search. The solution is not a better WordPress theme or a more expensive Webflow plan. The solution is a fundamental technology shift.

The Solution

What Astro.js means for your business

Zero JavaScript — maximum speed

Astro.js delivers pure HTML and CSS by default — without a single byte of JavaScript. Interactive elements are only loaded where needed (Islands Architecture). Result: load times under 0.5 seconds, even on slow mobile connections.

Sub-second load times (Lighthouse 95–100)

Our Astro.js websites consistently achieve Lighthouse scores of 95–100. This is not a marketing claim — it is measurable and verifiable. Google rewards fast websites with better rankings, and your visitors with a better experience.

AI-ready: Optimised for ChatGPT, Perplexity & more

Clean, semantic HTML, Schema.org markup, llms.txt, and structured data make your website readable and recommendable by AI assistants. We implement WebMCP standards so your content appears in AI-generated answers.

Hosting for CHF 0–5 per month

Astro.js generates static files that can be hosted on CDN networks like Vercel or Cloudflare for free or a few francs. No server maintenance, no PHP, no database management. Over 5 years, you save CHF 13,700 compared to WordPress.

No plugin dependencies, no security risks

WordPress needs plugins for everything — contact forms, SEO, caching, security. Each plugin is a potential security risk and maintenance burden. Astro.js has everything built in or uses secure build-time integrations. No attack surface, no updates.

Content Collections and Headless CMS

Edit your content through a simple CMS — no technical knowledge required. Astro.js Content Collections automatically validate your data. Compatible with Keystatic, Storyblok, Contentful, or any other headless CMS of your choice.

FAQ

Frequently asked questions

What is Astro.js?
Astro.js is a modern web framework released in 2022 that quickly became the preferred technology for performance-critical websites. The core idea: Astro delivers pure HTML by default — without JavaScript bloat. Interactive elements like forms or animations are only loaded where needed (Islands Architecture). The result is websites that load in under 0.5 seconds and achieve Lighthouse scores of 95–100.
Who is Astro.js suitable for?
Astro.js is ideal for business websites, landing pages, blogs, portfolios, documentation, and marketing sites — anywhere fast load times and SEO are critical. For highly interactive web apps (e.g., dashboards, social media platforms), we recommend Next.js or SvelteKit instead. For 90% of all SME websites, Astro.js is the best choice.
Do I need technical knowledge to manage my Astro.js website?
No. We set up a headless CMS for you (e.g., Keystatic or Storyblok) where you can edit text, images, and prices as easily as in Word. No technical knowledge required. The introduction takes 30 minutes.
What does an Astro.js website cost?
From CHF 3,490 for a professional website with 5–8 pages, responsive design, SEO setup, and contact form. Business websites with CMS and more pages from CHF 4,990. Premium projects with multilingual support from CHF 7,990. All prices are fixed — no surprises. Details at /en/pricing/.
Why not just use WordPress?
WordPress was the right choice in 2010. In 2026, it is a security risk with ongoing maintenance costs. 90% of all hacked websites run on WordPress. Load times of 3–5 seconds are standard. Monthly costs for hosting, plugins, and updates add up to CHF 200–400. Astro.js eliminates all these problems: no database, no PHP, no plugins, no updates. More at /en/technology/astro-js/.
Why not Next.js?
Next.js is an excellent framework — for web applications. For a business website, it is overkill: it delivers significantly more JavaScript than necessary, requires a server (higher hosting costs), and is more complex to maintain. Astro.js was specifically built for content-driven websites and beats Next.js on load time, hosting costs, and simplicity.
Can I edit my content myself?
Yes, from the Business package onwards, a headless CMS is included. You can edit text, images, blog posts, and prices through a simple interface — without touching any code. Changes go live within minutes.
How quickly will my website be live?
Simple websites (5–8 pages) are ready in 2–3 weeks. Business websites with CMS in 3–4 weeks. Complex projects with multilingual support or special features in 6–8 weeks. You receive a clear timeline with milestones.
Does Astro.js work with my existing CMS?
Astro.js connects to virtually any headless CMS: Keystatic, Storyblok, Contentful, Sanity, Strapi, Directus, or WordPress as a headless CMS. We recommend Keystatic for Swiss SMEs — simple, fast, and at no additional cost.
Is Astro.js future-proof?
Astro.js is developed by an active open-source team, has over 48,000 GitHub stars, and is used by companies like Google, Microsoft, and Netlify. The framework is continuously improved and has one of the most active communities in web development. We see no risk for the next 5–10 years.
