The Starting Point
The idea for fast.site was born from a real problem: Wiresoft.com, a large online store on Shopware 5, was losing SEO visibility due to poor load times. A platform migration was out of the question - too expensive, too risky.
Our solution worked so well that we decided to turn it into a standalone product. fast.site accelerates any existing website in minutes, without touching a single line of source code.
Challenge
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.
Approach
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.
Outcome
A production-ready SaaS product with a global edge network, self-service dashboard, and real-time monitoring. Wiresoft.com achieved Pagespeed scores of 90+ across all pages after integration.
From Client Project to Product
The Wiresoft Case
Wiresoft.com is a major software retailer running on Shopware 5. Despite relevant content and strong domain authority, their rankings were dropping - Google was penalizing the slow load times. A replatforming would have taken months and endangered ongoing operations.
The Caching Solution
Instead of rebuilding the system, we placed a caching layer 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.
From Solution to Product
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, without technical expertise.
Brand Identity
For fast.site we developed a standalone brand that communicates speed, reliability, and technical excellence.
Logo & Icon

Our load times improved drastically with fast.site, without changing a single line of code in our shop.
Infrastructure & Development
fast.site is built on a globally distributed edge infrastructure with intelligent caching strategies and automatic optimization of all web resources.
Architecture Decisions
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.
Dashboard
Nuxt 4 + Vue 3
Self-service frontend with real-time metrics, domain management, and caching configuration. 6 languages.
API
Go + REST
Central API for dashboard communication, nameserver validation, and edge configuration.
Edge Worker

Project Insights
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.
Wiresoft.com 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.
