Web design Heidelberg · WordPress agency & web agency
Websites that rank, load fast and convert.
Web design in Heidelberg from a web agency that has been based here since 2016: we build websites that load fast and turn visitors into enquiries. Whether classic with WordPress or modern with Astro, Next.js and headless Shopify, we think about conversion from the very first sketch, not just shortly before launch.

Built modern, delivered fast.
As a web agency, we build using tools that don’t get in our way. Where content can be delivered statically, we deliver it statically; we only use server-side rendering where necessary. An editorial CMS (WordPress or headless) is added if your team regularly updates content.
Astro
Our standard for content-driven sites. Astro delivers statically, achieves Core Web Vitals of 95+ and uses islands to load JavaScript only where a page needs interactivity.
Next.js & React
For projects with dynamic features, authentication or complex data flows. We work with the App Router and React Server Components (RSC) and pay attention to clean caching.
Shopify Headless
Conversion-optimised storefronts on Hydrogen or via the Storefront API. With no theme slowing things down, the shop stays fast. Find out more from our e-commerce agency.
Sanity, Contentful, Storyblok
A headless CMS that editors can navigate with ease. The content is structured, changes can be previewed beforehand, and previous versions are retained.
Tailwind v4 & design tokens
A token-based design system keeps the CSS tidy. The documentation is generated automatically, and the system can be applied to other pages.
Cloudflare, Vercel, Raidboxes
Where we host depends on load and budget. Edge caching and DDoS protection are included, and we use green hosting wherever possible.
From audit to launch. In 8 to 12 weeks.
We never start from scratch. Every project begins with an audit of your current website, your conversion data and your competitors.
We understand before we build
We start with a technical audit, heatmaps, funnel analysis and a look at the competition. You then receive a concrete list of hypotheses: what we will build and why.
Structure over appearance
Lo-fi wireframes based on the hypotheses. In parallel, we work on content briefs and the imagery concept. Sign-off happens in Figma.
Design system instead of individual pages
The pixel design is created directly in the token system. Rather than a single PSD, you receive a style guide system that can later be translated cleanly into code.
Clean implementation
We build the front end, CMS integration and tracking. Once a week, we go through the progress with you on the staging environment, so you can see every step.
Performance, tracking, go-live
Before going live, we check the Lighthouse scores, test the site in all common browsers, validate the tracking and complete the SEO migration. We support the launch and monitor the site for the first 14 days.
Iteration instead of a big bang
Every month we test improvements; once a quarter we review progress together. We either stay on board or hand over smoothly to your team.
What a web design agency really needs to deliver.
Good web design is more than an attractive layout. It combines visual design, web development and content into a website that suits your brand and works for your target audience. These are the building blocks we bring together.
It starts with strategy, not looks. During the concept phase, we clarify who you want to reach and what job the site should do for your target audience. Only then is the design concept created: imagery, web and graphic design, typography and an aesthetic that fits your corporate design and corporate identity or helps build a new brand. For us, professional web design means thinking about branding and design together. Both shape the impression visitors form of your company, and that impression should be an appealing one.
Then comes the craft. For us, web development means clean, efficient code rather than a pile of plugins, a clear information architecture with well-thought-out navigation and user guidance, and a front end that runs fast and reliably on every device. We use animation and motion sparingly and purposefully, where they help orientation, not for show. Which technology we use depends on the project: WordPress, a headless setup with Astro or Next.js and, if you wish, traditional CMSs such as TYPO3 if your company already works with them.
To help you choose a system, we’ve provided more detailed answers to the key questions: What is WordPress? explains the most widely used CMS, whilst WordPress alternatives put to the test compares the options. If your site runs on the Divi Builder, we’ll manage it for you as a Divi agency. The self-assessment Do I need a new website? helps you decide whether building a new site is even worth it.
For us, accessibility is a must, not an optional extra. Sufficient contrast, meaningful structures for screen readers and usable forms make a site accessible to more people and are increasingly relevant from a legal perspective in both B2B and B2C. That's why our web designers and developers work side by side, so that a good UX concept and the technical implementation don't drift apart.
As an agency specialising in websites and complete online presences, we work as a multidisciplinary team: experienced web designers, developers and SEO specialists collaborate to develop bespoke solutions that are both creatively and technically tailored to your industry. We plan strategically and do not incorporate features simply because they are the latest trend. Professional design and responsive design are just as much a standard part of our work as clean, well-crafted code.

Your web agency & WordPress agency in Heidelberg.
Our studio and team are based in Heidelberg, and we support companies from across the Rhine-Neckar Metropolitan Region.
As an agency for web design in Heidelberg based in Heidelberg, we work for companies from Heidelberg and the region that want to be found: from shops in the old town and trade businesses in Mannheim, Ludwigshafen and Wiesloch to B2B companies in the Rhine-Neckar district. If you want to have a new website built, you won't get an off-the-shelf website builder from us: from concept to build, we create bespoke web design that suits your brand and customers – modern, but without effects for their own sake.
If someone searches for „web design Heidelberg“, „web designer Heidelberg“, „web design agency Heidelberg“ or „WordPress Heidelberg“, your company should appear at the top of the results. That’s why, when it comes to your online presence, we pay just as much attention to the technical aspects as we do to the visual design: fast loading times, clean, responsive web design for smartphones, tablets and desktops, and a content management system that your team can maintain without any training – whether as a specialist WordPress agency in Heidelberg or using a headless setup. This turns your website into a tool that generates enquiries rather than just looking good.
Whether classic web design, bespoke web development or working with experienced web designers in Heidelberg: as a web design agency, we deliver projects with the know-how gained from more than 150 successfully completed projects and serve clients across Germany beyond the region. You'll notice our experience since 2016 and our expertise in design, technology and online marketing as early as the free initial consultation.

Frequently asked questions about web design.
Do you build with WordPress or with Astro?
Both - it depends on your project. WordPress is an excellent content management system if your team maintains a lot of content itself and wants a familiar editorial back end. For highly performance-critical marketing sites, we use Astro with a headless CMS instead, which offers the same editing experience with 5-10x faster loading times. We build clean WordPress without plugin sprawl just as well as modern headless setups - and we'll tell you honestly which makes more sense for your plans.
Are your websites optimised for all devices?
Yes. We build every website consistently with responsive web design: it looks equally good on smartphone, tablet and desktop and loads quickly everywhere. As most visitors now arrive on mobile, we design the layout mobile-first and then extend it for larger screens.
Is the website GDPR-compliant and secure?
We build with data protection in mind: GDPR-compliant tracking, a clean consent banner, minimal use of personal data and hosting in the EU. With WordPress, we keep the core, themes and plugins up to date as part of our support so that your site stays secure. If you wish, we can take care of maintenance and updates on a retainer.
What happens to our current SEO rankings during a relaunch?
We always migrate with full URL mapping and 301 redirects. In our last 14 relaunches, we have seen an average gain of 5–8 per cent in organic traffic in the first 90 days, not a loss. SEO migration is an integral part of every project, not an add-on.
Can we maintain the site ourselves after launch?
Yes. We build with a headless CMS (Sanity, Storyblok, Contentful) that your editors will understand within 30 minutes. You receive a Loom walkthrough, a PDF manual and a WhatsApp channel for questions. You are not tied to us - any other provider can continue working with it later.
Who writes the content?
You or your team. We provide briefs, structures and SEO guidelines. If you want to outsource content, we can put you in touch with two copywriters we have worked with for a long time - or support you directly with our SEO content team.
What if I only need a landing page?
That works. We have a streamlined process for landing pages, from audit to go-live in four weeks. If you need landing pages on a regular basis, a retainer is worth considering.
Does a new website automatically lead to better search rankings?
Not automatically, but it lays the foundation. A new website ranks better when technology, structure and content work together. That's why we build with search engine optimisation in mind: fast loading times, a clean page structure, meaningful headings and structured data. Whether a particular term ranks at the top ultimately also depends on content and links, not on design alone. You can see how we combine design and visibility on the page about our SEO agency in Heidelberg.
Do you work with ready-made templates or bespoke web design?
We create bespoke web design, not off-the-shelf templates. Every website is tailored to your brand, your target audience and the scope of your project. We use ready-made templates at most as a quick reference during the concept phase, never as the final product. We’ll clarify what makes sense for your project in advance, with no obligation, during a free initial consultation.
Which companies in Heidelberg benefit from professional web design?
For anyone whose website is out of date, doesn’t work properly on a smartphone or generates hardly any enquiries. Whether you’re a tradesperson, a law firm, a medical practice or a B2B business: professional web design is worthwhile as soon as you want your business to be found online and to turn visitors into customers. In a free initial consultation, we’ll give you our honest opinion on whether the investment will pay off for you.
Do you also work with TYPO3 or other existing systems?
Yes. If your company already works with TYPO3 or another established CMS, you don't necessarily have to switch. We assess honestly whether moving to WordPress or a headless setup brings a real advantage or whether it makes more sense to develop the existing system further. For us, bespoke web development means choosing the technology based on your plans, not on the latest trend.
How does a website project work at your web design agency in Heidelberg?
We start with a free initial consultation to clarify your goals and ideas. This forms the basis for a bespoke concept tailored to your individual requirements: information architecture, design concept, technology and timetable. Throughout the project, you’ll be able to view every step in a staging environment and provide your feedback during scheduled review sessions. From conception to launch, a typical website project with us takes 8 to 12 weeks.
Do you also work with companies in Mannheim, Ludwigshafen and the surrounding region?
Yes. Our studio is based in Heidelberg and web design for Heidelberg is our core business – but as web design experts, we also support businesses across the region: from Mannheim and Ludwigshafen right through to the entire Rhine-Neckar district. For businesses in the Rhine-Neckar Metropolitan Region, face-to-face meetings on site can be arranged at short notice; many projects can also be carried out entirely remotely if requested. What matters is not the distance, but that the website ultimately generates measurable enquiries.
Does my company need a completely new design, or is optimisation enough?
That depends on the state of your website. If the technology is solid and only the look has aged, a new design on the existing foundation is often enough. If, on the other hand, the underlying setup is holding you back - slow loading times, an outdated CMS, no responsive design - a relaunch is usually more cost-effective than years of patching. In the free audit call, we'll tell you honestly which route makes sense for your website.
30-minute audit call.
Free and honest.
We’ll take a look at your current website and your conversion data together and let you know whether a relaunch is worthwhile – even if the answer is ‘not yet’.
