Frequently Asked Questions

Answers about Web- & App-Entwicklung and our services

Click on a question to see the answer.

App development costs: Simple app €15,000-30,000, medium complexity €30,000-60,000, complex enterprise app €60,000-150,000+. Cross-platform (React Native, Flutter) is 30-40% cheaper than native development for iOS and Android separately.

Next.js is built on React and offers: Server-Side Rendering (better for SEO), automatic code splitting, API routes, image optimization. For websites and web apps, we recommend Next.js. For SPAs without SEO needs, pure React is often sufficient.

A headless CMS (e.g., Payload, Contentful, Strapi) separates content management from frontend. Benefits: flexible frontend (React, Vue), better performance, omnichannel use (web, app, IoT). Ideal for complex projects with multiple output channels.

Development times: MVP/prototype 2-3 months, standard web app 3-6 months, complex software 6-12+ months. We work in 2-week sprints with regular demos. Accurate estimates possible after requirements analysis.

Vercel: optimal for Next.js, simple deployment, automatic scaling, edge functions. AWS: more control, cost-effective at scale, more complex to manage. For Next.js projects, we recommend Vercel; for complex infrastructure, AWS/GCP.

CI/CD (Continuous Integration/Continuous Deployment) automates: code tests on every commit, automatic builds, deployment to staging/production. Benefits: fewer errors, faster releases, consistent quality. Tools: GitHub Actions, GitLab CI, CircleCI.
