Web development: fast, modern websites & web apps
Web development at Rocket-Monkeys from Munich means fast, accessible websites and web apps built from scratch – on a modern stack of Astro, TypeScript and Tailwind, cleanly structured so that both humans and AI systems understand them. You don't just get a good-looking site, but a technical foundation that stays visible in Google and in AI answer engines like ChatGPT and Perplexity.
Most websites are slow, hard to maintain and poorly set up for search – not because the design is bad, but because the technology underneath is wrong. Bloated page builders, a hundred plugins and megabytes of JavaScript nobody needs: that costs load time, rankings and, in the end, customers. We build it differently.
We develop websites and web apps from the ground up instead of clicking together templates. Our default stack is Astro for lean, fast sites, TypeScript for robust code, Tailwind for a consistent, maintainable design system, and Node for everything that has to run in the background. The result: sites that load in milliseconds, work on every device, and that you – or we – can still evolve comfortably two years from now.
The decisive difference is under the hood: semantic, cleanly structured HTML and machine-readable data (JSON-LD). That's exactly the bridge to being found in AI search. A site that's clearly readable for crawlers and language models has a far easier time getting cited in the answers of ChatGPT, Perplexity and Google AI Overviews. We build your site that way from the start – not as a retrofit, but as the foundation.
We typically work with companies and mid-sized businesses that want to replace an outdated, slow site or need a performant web app that part of their business runs on. As a small, focused agency from Munich, we stay close, go technically deep and work bilingually (DE/EN) – across the entire DACH region.
What you get
Noticeably fast, measurably good
We optimize consistently for Core Web Vitals and real-world load times. Fast sites convert better, rank better and simply feel better to use – and you see the numbers in black and white, not just as a promise.
Built for the search of tomorrow
Clean, semantic markup and structured data make your site crawlable and citable – for Google as well as for AI answer engines. That keeps you visible where more and more people now search.
Clean code that won't become a liability
TypeScript, clear components and a documented stack mean no plugin jungle and no vendor lock-in. You can keep building yourself or continue with any agency – the site stays maintainable.
Accessible to everyone
We build oriented to the WCAG standards: keyboard operability, contrast, correct structure. That reaches more people, reduces legal risk and, as a bonus, improves machine readability too.

- Headless CMS integration – so you can edit content yourself without touching code
- Hosting, deployment & maintenance – cleanly set up, automated, ready to hand over
How it works
Understand & plan
We clarify goals, content and technical requirements and find where a site or web app truly makes an impact. From that we shape a clear concept of structure, stack and scope – no flying blind.
Design & structure
We design the layout and design system and define the semantic structure early – meaning how humans and machines read the site. We treat findability as a starting point, not an afterthought.
Build & test
We develop with Astro, TypeScript and Tailwind and check performance, accessibility and rendering on real devices. You see work-in-progress live and give feedback as we go.
Launch & support
We go live cleanly, set up hosting, analytics and monitoring, and hand over a site you can maintain yourself. On request, we stay on board for further development and upkeep.
Frequently asked questions
What does a new website cost at Rocket-Monkeys?
A lean, modern website at Rocket-Monkeys starts in the low four figures, while larger web apps are scoped by effort. The price depends on the number of pages, the features and the content involved. In a free intro call we clarify your goal, the effort and a realistic budget – before you commit to anything.
Why do you build with Astro instead of WordPress or a site builder?
Astro produces extremely lean, fast sites out of the box because it only ships the JavaScript that's actually needed. Compared to classic WordPress or site builders, that means better load times, cleaner structure and no plugin security holes. When a project needs a CMS, we connect a modern headless CMS – so you edit content comfortably without sacrificing performance.
Can we edit content ourselves?
Yes. On request we connect a headless CMS where you edit text, images and pages yourself – entirely without code. Alternatively, we maintain content for you as part of ongoing support. What makes sense depends on how often your content changes.
What does web development have to do with AEO and AI visibility?
A great deal: how a site is built technically largely determines whether AI systems can understand and cite it at all. Clean, semantic HTML and structured data make your content readable for crawlers and language models like ChatGPT or Perplexity. That's exactly why we always build web development and findability (AEO/SEO) together – the technology is the foundation visibility is built on.
Do you also handle relaunches of an existing site?
Yes, relaunching an outdated or slow site is one of our focus areas. We analyze what exists, preserve current rankings through clean redirects and move your content onto a modern, fast stack. That way you gain speed and visibility without losing the SEO value you already have.
