Four-day developer conference in Mannheim bringing together over 2,500 software engineers for 170+ sessions and workshops on .NET, web development, cloud, DevOps and AI. Germany's main practitioner-focused annual conference for software developers, conducting sessions in German and English.
DWX (Developer Week) is the annual developer conference organised by Ebner Media Group through its Developer World brand. Running since at least the mid-2010s in Mannheim, it is one of Germany's largest practitioner-focused software development conferences, covering .NET, web technologies, cloud infrastructure, DevOps and AI. The 2026 edition spans four days with one workshop day (Monday, 29 June) followed by three days of concurrent conference sessions, networking events and community meetups.
DWX occupies a specific position: it runs primarily in German (with some English sessions), which serves the large German-speaking developer market not fully reached by English-only conferences. The conference emphasises technical depth, with sessions averaging 60 minutes and covering implementation-level content rather than vendor pitches. The four-day format, combined with workshops and evening events, makes it a full professional development retreat.
The 2026 programme delivers 170+ sessions across tracks covering .NET development, web development, cloud and DevOps, software architecture and patterns, AI and generative AI, and data and analytics. Workshop day on Monday 29 June offers half-day and full-day workshops for in-depth hands-on learning. Conference sessions run from Tuesday 30 June through Thursday 2 July with concurrent tracks across the conference centre.
Workshop day (Monday, 29 June) runs half-day and full-day workshops with lunch and breaks included. Session days (Tuesday to Thursday) feature 170+ talks in parallel tracks, approximately 60 minutes each. The programme also includes networking breaks, speaker meet-and-greets, evening community meetups, and the DWX Casino Night. Expo talks from sponsors supplement the main programme.
Dr. Larysa Visengeriyeva delivers a keynote on responsible AI operationalisation, covering how EU AI Act requirements translate into practical technical workflows. The full speaker list (150+ confirmed speakers) is published at developer-world.com/dwx. Conference Chair: Fernando Schneider, Editor-in-Chief of Developer World.
Platinum: ITech Progress GmbH. Silver: fecher GmbH, innoQ Deutschland GmbH, msg group. Bronze: combit GmbH, Exxeta AG, MESCIUS, oose eG, sepp.med gmbh, Text Control GmbH, Xebia. Ebner Media Group publishes several German developer magazines (Entwickler Magazin, Java Magazin) which serve as media partners.
.NET is one of the major tracks but not the only one. DWX covers web development, cloud, DevOps, AI and architecture in parallel. Developers working outside the .NET ecosystem attend for web, cloud and AI content.
The majority of sessions are in German, consistent with the conference's role in the German-speaking developer market. Some sessions are in English. The programme indicates the session language for each talk.
DWX is focused on the DACH market and operates in German, unlike pan-European conferences such as Devoxx (English, Belgium) or NDC (English, Norway). In size and format it is comparable, with 2,500+ attendees and 150+ speakers, but it serves a distinct linguistic and geographic audience.
The Rosengarten Congress Center in central Mannheim is a professional event venue with multiple halls and breakout rooms, suited to multi-track conferences of this scale. Mannheim is served by direct rail connections from Frankfurt, Stuttgart and Munich. The ICE train from Frankfurt takes approximately 35 minutes.
Ebner Media Group is a German B2B media and events company publishing trade magazines across technology, design and industrial sectors. Developer World is its developer-focused brand, responsible for DWX and related events. Fernando Schneider serves as Editor-in-Chief and Conference Chair for DWX. The group publishes Entwickler Magazin and Java Magazin, which provide editorial coverage of the conference. The Developer World LinkedIn page tracks news between editions.
DWX is Germany's main annual practitioner conference for software developers, filling the German-language gap left by English-only European conferences with deep .NET, web and AI content for the DACH market.
