Project Overview
Pagespeed
Performance Score
The idea for fast.site grew out of solving a problem we run into constantly in our everyday work. Many clients with large, outdated shop systems like Shopware 5 lose their web presence as Google keeps adjusting its Pagespeed metrics. To improve these systems' performance without a lengthy migration to a new platform, we built a caching solution.
We had been using this solution on select projects, then developed it into a product: set up in minutes, secure and global, with no source-code changes.
Many businesses run websites on legacy systems like Shopware 5, Magento, or WordPress. These pages load slowly, have poor Core Web Vitals, and lose SEO rankings as a result. A full platform migration is often neither realistic nor economical.
We built a global CDN with intelligent caching strategies, automatic image and resource optimization, and edge computing. A simple nameserver change routes traffic through our network, the existing site stays untouched.
A production-ready SaaS product with a global edge network, self-service dashboard, and real-time monitoring. The first store we deployed it on reached Pagespeed scores of 90+ across every page after integration.
Origin Story
We kept seeing the same setup: a large client running a big, content-heavy shop on legacy Shopware and aging hardware. Rankings slip because Google penalizes the slow load times, but migrating a live store to a modern platform is a multi-layered risk. It is expensive, it threatens daily operations, and it drags on into a slow, mammoth project.
Instead of rebuilding the system, we put a cache in front of it. Static resources, optimized images, and compressed HTML are delivered at the edge. The origin server is only contacted for actual data changes. The result: load times under one second.
The results were so compelling that we productized the solution. fast.site makes the same approach accessible to any website operator, in minutes instead of months and without technical expertise.
Branding
For fast.site we developed a standalone brand that communicates speed, reliability, and technical excellence.
The logo combines the brand name with a dynamic icon symbolizing speed and global connectivity. The color palette of red, green, blue, and gold reflects the diversity of supported platforms.
Primary Blue (#1C5FFB) as the lead color represents trust and technology. Accent colors in red, green, and gold mark different product areas and status indicators in the dashboard.

Technical Architecture
fast.site is built on a globally distributed edge infrastructure with intelligent caching strategies and automatic optimization of all web resources.
Global edge network for minimal latency. Static and dynamic content is cached at the nearest point of presence.
Automatic image conversion to WebP/AVIF, CSS/JS minification, Brotli compression, and critical CSS inlining, all at the edge without origin contact.
Intelligent cache invalidation detects content changes and updates only affected resources. No manual purging required.
Nuxt 4 + Vue 3
Self-service frontend with real-time metrics, domain management, and caching configuration. 6 languages.
Go + REST
Central API for dashboard communication, nameserver validation, and edge configuration.
Go + Caching
Global edge servers for caching, image optimization, compression, and SSL termination.
Global Edge
20+ edge locations worldwide. Automatic routing to nearest PoP, health checks, and failover.
Tech Stack
Features
Intelligent caching at the nearest edge server with automatic invalidation on content changes.
Automatic conversion to WebP/AVIF, lazy loading, and responsive image delivery without manual effort.
The latest web protocols like HTTP/3 plus Brotli compression for the fastest possible data transfer.
Built-in DDoS mitigation absorbs attacks at the edge before they ever reach your origin.
Free SSL/TLS certificates with automatic renewal for every connected domain.
Live dashboard with bandwidth, cache hit rate, load times, and traffic per domain.
Deliverables
Technical details and key decisions behind fast.site.
Existing CDNs like Cloudflare or Fastly offer generic caching. fast.site goes further: automatic image optimization, CMS-aware cache invalidation, and Core Web Vitals optimization are deeply integrated rather than bolted on as add-ons.
The customer switches their nameservers, that's it. From that moment, all traffic flows through our edge network. No plugins, no code changes, no deployment.
The first store we deployed it on went from Pagespeed scores below 40 to over 90 on both desktop and mobile. Time-to-First-Byte dropped from over 2 seconds to under 200ms. Those were the numbers that convinced us to turn it into a product.
The dashboard is a Nuxt 4 application with Radix Vue components and Tailwind CSS. The API behind it is written in Go and communicates with the edge servers through a custom protocol.
