Capability 02 / Web development
Web developmentthat still runsin 5 years.
Web development
Web development is the technical implementation of a site, shop or application — frontend code, CMS, database, infrastructure. At soy. webdesign in Stuttgart we build with Next.js, React and TypeScript on modern standards (App Router, Server Components, Edge runtime) combined with headless CMS like Payload, Sanity or Strapi. Result: sites that meet Core Web Vitals long-term, are quotable by search and AI engines, and remain maintainable five years out — no lock-in, no page-builder debt.

Our stack — narrow on purpose
Few tools, deeply mastered. Less exciting than the trend zoo, but it means: fewer bugs, faster releases, lower onboarding cost when somebody new joins on either side.
- Frontend: Next.js 16 (App Router, Server Components, Turbopack), React 19, TypeScript strict.
- Styling: Tailwind v4 with design tokens, no CSS-in-JS runtime.
- CMS: Payload 3 (Node-native in Next), Sanity, Strapi, or WordPress + Gutenberg.
- Backend: Node.js, tRPC or REST, Postgres or MySQL, Redis for cache.
- E-commerce: Gambio (PHP, custom modules), Shopware 6, headless with Stripe/Paddle.
- Infra: Docker on Netcup or Hetzner, Vercel, or your own hosting.

What we build
Three project types make up 90% of our work. They share one trait: very little JS in the browser, fast CMS, and they can be evolved without us.
- Sites + brand portals with custom design systems, multilingual, editor-friendly.
- Shops on Gambio (Pokejoy = our own with five-figure customer base), Shopware, or headless.
- Web applications with auth, custom data models, third-party integrations.

Web development doesn't end at launch. Maintenance retainers from €290/month: framework + dependency security updates, backup monitoring, smaller changes, quarterly performance + SEO reviews. Larger changes billed by sprint. Month-to-month cancellation.
FAQ
Antworten, bevor du fragst.
What technologies do you use?
Frontend: Next.js, React, TypeScript, Tailwind. Backend: Node.js, PHP (Laravel/Gambio), Postgres, MySQL, Redis. CMS: Payload, Sanity, Strapi, WordPress (Gutenberg). Hosting: Docker on Netcup/Hetzner, Vercel, on-prem.
What does a web application cost?
Small (internal dashboard with auth + CRUD): from €18,000. Mid-size platforms with roles, payments, integrations: €35,000–80,000. Complex SaaS: €80,000+ priced per sprint.
Why Next.js instead of WordPress or a page builder?
Page builders look fast at build time but cost compoundly in performance, SEO and maintainability. Next.js gives full control, best Core Web Vitals, easy scaling, a frontend that can still be understood and extended in five years.
Do you do headless commerce?
Yes. Next.js plus Shopify Plus, Commercetools or Saleor with custom listing, PDP and checkout. Or classic with Gambio / Shopware depending on size.
How do you handle GDPR?
EU/DE hosting. Cookie consent with script blocker (third-party scripts only after explicit consent). Plausible or self-hosted Matomo over Google Analytics where possible. DPAs with all sub-processors.
How long does development take?
Standard site with headless CMS: 6–10 weeks. Shop: 10–16 weeks. Web app with custom backend: 12–24 weeks. Sprint-shippable build every two weeks.
Do you do frontend-only?
Yes. If you have an existing backend, API or headless CMS, we can plug a Next.js frontend on top. Common in migration and headless-commerce projects.
What does handover include?
Code in your own Git repo, README, deployment.md, ARCHITECTURE.md. One hour of live training per role (editor, dev, admin) included.
