From Internal Tool to Own SaaS: We Launch the Beta Phase of Viewcel

There is that one moment when you stop being frustrated with inadequate software and decide: We're doing this ourselves now.

While we have been implementing client projects over the past six months, a silent revolution has been taking place in the background. We critically examined key components of our tech stack. Particularly in the areas of monitoring and quality assurance, we had enough of expensive licenses for tools that ultimately were just compromises. We paid premium prices, but the performance often didn't match our specific requirements.

So we rethought this part of our infrastructure. Instead of begrudgingly paying invoices, we decided: We will build the solution ourselves. Better. Faster. And smarter.

Today, we are incredibly proud to present the first result of this journey: Viewcel.

Why We Built Viewcel

In our web and app projects, stability is not an option but a necessity. For years, we used common tools to track visual changes. But often the result was disappointing: You got a screenshot full of red markings and had to guess yourself – is this a critical bug or just a pixel shift?

We wanted a system that works "pixel-perfect" but is smart enough to understand the context.

The result is Viewcel: A monitoring tool built by developers for developers. API-first, scalable, and with AI that makes a difference.

The Heart: AI-Powered Analysis

Viewcel doesn't just send you a "before-and-after image". Our integrated AI engine scans every pixel, analyzes the layout, and categorizes changes intelligently:

• Content vs. Layout vs. Style: The AI immediately recognizes: Was only a text changed? Has a button shifted (layout)? Or has the color changed (style)?
• No More Noise: Thanks to intelligent filters, we ignore irrelevant dynamic content and alert you only when it's really important.
• Explanation Instead of Puzzle: You get understandable insights into what exactly happened on your page.

Enterprise-Grade Features: Ready for Scaling

We designed Viewcel to not only monitor small sites but also massive infrastructures:

• Sitemap Intelligence & Bulk Import: You don't have to add each URL individually. Simply copy your sitemap URL, and Viewcel imports and monitors hundreds of pages in seconds. This way, you keep an eye on the health of your entire domain.
• API-First Design: Viewcel can be fully automated. Integrate monitoring directly into your CI/CD pipeline or build your own dashboards on it.
• Enterprise Ready: Security has been a priority from day one. We use 256-bit encryption, are GDPR-ready, and align with SOC 2 standards.

Vibe-Coding Meets Engineering

Viewcel is also proof of how we build software today. It is the result of Vibe-Coding (rapid prototyping with AI support), combined with real software engineering expertise.

For our Department "Softwareentwicklung", Viewcel is a true masterpiece. It shows that we are not just service providers but capable of planning and operating complex, highly available SaaS architectures from scratch. The AI helped us pick up speed – but the architecture and scalability are based on a modern tech stack that we specifically chose for performance:

• Hetzner Cloud & Docker: This is where the real "muscle power" lies. We operate a flexible Docker cluster on high-performance Hetzner VMs. The trick: Our screenshot workers (based on Headful Chrome) run in isolated containers. When load peaks occur, we simply replicate these workers dynamically. This allows us to render and analyze thousands of pages in parallel without performance taking a hit.

• Nuxt.js (Frontend & Backend): The intuitive Vue framework forms the backbone of the application. It enables us to have an extremely fast user interface and efficiently handle server-side logic in one go.

• Supabase: We use Supabase as backend infrastructure. This allows us to benefit from the stability of a PostgreSQL database combined with modern real-time features for instant updates in the dashboard.
