Germany's flagship conference for software developers, bringing together over 2,500 practitioners for four days of workshops, sessions and community networking across AI, cloud, .NET, web development and DevOps in Mannheim.
DWX, short for Developer Week, is a multi-day developer conference held annually in Mannheim, Germany. Organised by Ebner Media Group, a German technical media group that also publishes the dotnetpro magazine, it covers the full stack of enterprise software development with particular strength in Microsoft/.NET, cloud infrastructure, web development, AI and software architecture. The event runs across four days: one day of hands-on workshops followed by three days of plenary sessions, and includes structured networking formats and an evening social event known as the DWX Casino Night.
The 2026 edition takes place at the Congress Center Rosengarten (m:con) in Mannheim from 29 June to 2 July 2026. According to the organiser, the programme includes over 170 sessions and 12 workshops delivered by more than 150 speakers. Workshops on 29 June run in half-day or full-day formats, with technical deep-dives on topics ranging from generative AI to microservices. Conference sessions from 30 June to 2 July run at approximately 60 minutes each. The organiser reports attendance of over 2,500 participants.
DWX occupies a distinct position as a practitioner-oriented, German-language-primary developer event in the DACH region. It sits closer to the developer-tool and software-craft end of the spectrum than to startup pitching or product launches. In the European calendar, it is broadly comparable in audience and format to events such as WeAreDevelopers World Congress (Berlin) or Jfokus (Stockholm), though DWX retains a more pronounced .NET and German enterprise software orientation. The event has been running for over 12 years according to the organiser.
The audience is composed primarily of practising software developers, software architects and technical leads working in German-speaking markets and broader European enterprise software environments. The session track structure, which covers .NET, web, cloud, DevOps, AI and architecture as distinct topics, reflects a developer audience with a range of seniority levels and technical specialisations. Partner organisations at the 2026 edition include IT consulting firms such as innoQ, msg group and ITech Progress, as well as enterprise technology vendors, indicating a corporate and mid-market buyer base alongside individual practitioners.
The four-day programme is structured as follows:
The venue, m:con Congress Center Rosengarten, is a purpose-built conference facility in central Mannheim. The organiser has negotiated reduced hotel rates at the Dorint Kongresshotel Mannheim adjacent to the venue, and a Deutsche Bahn rail discount is available for travel to the event.

It is aimed at software developers and architects in the German-speaking market and DACH enterprise environment, with content primarily in German. The organiser is a technical publisher rather than a consultancy or vendor, which shapes the editorial orientation of the programme.
According to the organiser, DWX has been running for over 12 years. The 2026 edition is presented as a continuation of an established annual event.
