Case Study · JET-CMS

High-Performance CMS for fast campaigns.

We want to make marketing teams independent. So we built JET-CMS: a fast, secure CMS with a component editor, AI translations, and clean architecture on Next.js & Vercel.

The story

From request to our own solution

  1. 01

    The request

    It all started with a seemingly simple question: “Can you renew our website?” We normally don't build simple websites – our strength lies in complex web applications.

  2. 02

    Our recommendation

    A custom relaunch would be considerably more expensive than standard solutions. So, taking our responsibility as consultants seriously, we recommended WordPress or Webflow.

  3. 03

    The reality

    The client already had WordPress but couldn't maintain the site: too complicated, too much fear of breaking something. As a result, the website had grown outdated. We took another close look at the tools – and felt the pain ourselves.

  4. 04

    The decision

    At that point, we had to admit the client was right. So we decided to build our own solution – a CMS that meets exactly the needs of this scenario.

If maintaining a marketing website is frightening, something is fundamentally wrong.

Requirements

What we set out to build

01

Radically simple

Creating and changing content has to work without instructions.

02

100% customizable

Every brand design must map pixel-perfectly.

03

SEO & performance out of the box

Core Web Vitals and clean engineering, correct by default.

The result

What it became

JET-CMS is our result – a CMS that meets exactly the needs of this scenario. The key building blocks:

  • Component editor: A lean editor that makes changes possible in minutes, without endangering the corporate identity.
  • Next.js & Vercel with EU hosting: Optimized render paths and a clear architecture.
  • AI-supported multilingualism: Translations are created with AI support, while approval stays with the team.
  • SEO basics & performance: Built in rather than a “nice to have”.
Impact

Impact for the client

Maintenance without fear Content is maintained without fear and without IT loops.
Live in hours New pages go live in hours – not in weeks.
Fast & stable The website stays fast and stable; Core Web Vitals are reliably in the green.
100% corporate look The design stays 100% on brand, without makeshift solutions.

We are very satisfied with the result: JET-CMS meets all the criteria we set ourselves. The first clients are already using it in production.
