Warum Custom Development?

Website builders are fast – but limited. Real solutions require custom-tailored code.

Performance

Website builder templates often load 2-5 MB JavaScript for features you never use. Custom Code means:

  • Only what you need
  • 0.8s instead of 4.2s load time
  • Perfect Lighthouse scores
🎨

Unlimited Flexibility

Website builders force you into predefined layouts. With us, there are no limits:

  • Any design vision implementable
  • Custom-tailored features
  • No plugin dependencies
🔄

Real Automation

From Make.com integrations to completely custom programmed workflows:

  • API-Integrationen (CRM, Analytics)
  • Custom Automations & Scripts
  • Telegram, Slack, Webhooks

The difference: Website builder templates cost €20-50/month, force you into rigid layouts and load unnecessary code. Custom Development costs more once – but you own the code, have full control and zero ongoing SaaS costs.
