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.
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.
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.
