Streaming Record Numbers at ZDF: JAKALA Powers the Technology Behind It. For the Future.

This was reported by outlets including meedia.de. Just three weeks after these record-breaking figures, in March 2025, the new streaming platform launched as the successor to ZDFmediathek—reimagined and implemented technologically by JAKALA.

Systematic Performance Focus – For the User Experience

As ZDF’s long-standing digital partner, JAKALA played a key role in transforming the Mediathek into a streaming platform. From backend architecture and data logic to a wide range of frontend touchpoints on smartphones, web, and smart TVs—the new platform was designed with a clear focus on performance, scalability, and user experience. At the heart of the new architecture are Next.js 15 and a custom-built GraphQL backend.

Next.js 15 introduces a modern rendering architecture that flexibly combines server-side and client-side rendering. This not only enables faster load times but also improves SEO performance and shortens development cycles.

The tailored GraphQL backend ensures efficient and targeted data queries. Instead of loading large amounts of unnecessary data, frontends receive exactly the information they need—a crucial advantage when handling millions of simultaneous accesses.

With the combination of platform architecture and highly optimized delivery through powerful frontends, JAKALA proves: those who prioritize performance are not only ready for peak loads but also enable a seamless experience for all users—and the next streaming success story.

JAKALA has been primarily responsible for ZDF’s digital delivery channels for nearly three years. In addition to experience design and frontends, JAKALA also manages the infrastructure behind the streaming portal in close collaboration with ZDF’s Digital Products and Automation division, and as general contractor in a consortium with Axinom, Condat, and HBT.
