OUR STACK
The architecture behind the performance.
While agencies debate WordPress vs Squarespace, we engineer custom platforms on the same technologies used by Vercel, Shopify, and Netflix. Here is what powers every Cognitex build.
Frontend
Astro
The framework built for speed. Static-first rendering with zero JavaScript by default. Every page loads in under 1 second.
React
Interactive islands only where needed. No unnecessary hydration, no wasted client-side resources.
TypeScript
Strict type safety across the entire codebase. Fewer bugs, better developer experience, more reliable deployments.
Tailwind CSS
Utility-first styling with zero unused CSS in production. Pixel-perfect designs without bloated stylesheets.
Headless Commerce
Medusa
Open-source headless commerce platform. Full control over the shopping experience with no vendor lock-in or monthly fees.
Headless Shopify
When clients need the Shopify ecosystem, we build on Hydrogen for custom storefronts that outperform standard Shopify themes.
Stripe
Enterprise-grade payment processing. Subscriptions, one-time payments, and multi-currency support built in.
AI & Automation
Voiceflow
Conversational AI for online booking and handling inquiries across chat and calls.
OpenAI / Claude
AI-powered customer communication, content generation, and intelligent booking systems that work 24/7 in Bulgarian and English.
Infrastructure
Netlify / Vercel
Edge deployment with global CDN. Your site loads fast from anywhere in Europe, with 99.99% uptime.
Cloudflare Turnstile
Invisible bot protection on every form. No puzzles for real visitors, no spam in your inbox.
Why this matters
Most agencies use monolithic platforms (WordPress, Wix, Squarespace) that bundle everything into slow, rigid systems. Our headless approach separates the presentation layer from the data layer, giving you:
Sub-second page loads (vs 3-5s for WordPress)
90-100 Lighthouse scores as standard
Total design freedom with no theme limitations
Unlimited scalability without performance degradation
Smaller attack surface with no plugin vulnerabilities
Structured for AI answer engines (AEO-ready)
The decisions behind the stack
The technology list says what we use. What matters more is what we decided with it, because that is the difference you feel in a delivered site. Every example below is true of the page you are reading right now.
JavaScript by exception, not by default
Pages are generated statically at build time. React hydrates only where there is real interactivity, and even then it waits: menus and modals load when the browser is idle, sections when they enter the viewport. The result is a site search engines and AI assistants can read without executing any JavaScript.
Third-party scripts wait their turn
Google Tag Manager does not load when the page opens. It waits for the first scroll, click or tap, and loads after a few seconds if none comes. Analytics should not be the first thing that slows a visitor down.
Checks run in the build, not off a manual list
Before anything is published, an automated pass fails the build on a broken internal link, a wrong hreflang, missing alt text, an over-long title, or a page missing from the sitemap. A rule that only holds when someone remembers it is not a rule.
Smooth scrolling switches itself off when it hurts
The smooth-scroll library is disabled on Safari, on touch devices, on slow connections, when reduced motion is requested, and on low-end hardware. An effect that looks good on a fast laptop and stutters on an average phone is a loss, not a feature.
