First in-person edition of the GenAI developer conference, held at the Radisson Blu Mannheim on June 10-11, 2026, with an optional workshop pre-day on June 9. 24 sessions across two tracks, organised by Rheinwerk Verlag and Heise Medien.
The betterCode() GenAI Summit is a developer-focused conference on the practical use of generative AI in software development. The 2026 edition at the Radisson Blu Mannheim was its first in-person edition, after previous online-only runs. The programme covered 24 sessions across two parallel tracks over two days, June 10 and 11, preceded by an optional workshop day on June 9. The event is organised by Rheinwerk Verlag and Heise Medien, the German technology publishing group behind iX and c't.
The conference ran 24 sessions across two tracks over June 10 and 11, with a hands-on workshop day on June 9 ahead of the main programme. Content stayed at the practitioner level: coding agents, AI-assisted testing, legacy code migration, spec-driven development, and the security of agentic systems. The Rheinwerk Verlag and Heise Medien backing means the audience skewed toward the German-speaking developer community.
betterCode() is a conference series run by Rheinwerk Verlag and Heise Medien targeting German-language software developers. Other events in the series cover topics including API design, software architecture, and mobile development. The GenAI Summit applies the same developer-practitioner format to generative AI.
Given the organisers, Heise Medien, publisher of iX, and the Mannheim venue, the conference was primarily German-language. The language of proceedings is not separately confirmed by the organiser.
Previous editions of the betterCode() GenAI Summit ran as online events. The 2026 Mannheim edition was the first in-person format, adding a workshop pre-day and on-site networking.
The Radisson Blu Hotel Mannheim sits at Q7 27, 68161 Mannheim, in the city's central grid quarters, with dedicated conference facilities. Mannheim is in the Rhine-Neckar metropolitan region, connected by ICE high-speed rail to Frankfurt (about 40 minutes) and Stuttgart (about 35 minutes).
Heise Medien is one of Germany's leading technology publishing groups, operating heise.de and print titles including iX and c't. Rheinwerk Verlag is a German technical book publisher. Together they ran the betterCode() GenAI Summit as part of a wider slate of developer-focused events for the German-speaking market.
The first in-person betterCode() GenAI Summit gave the German developer community a focused, practitioner-level programme on generative AI in everyday software work, with speakers from Deutsche Telekom, IONOS, Hermes, and Vorwerk grounding the agenda in production reality rather than vendor demos.
Registration ran at genai-summit.bettercode.eu. The early bird ticket was priced at EUR 999 plus VAT. The event has now taken place; this fiche documents the 2026 edition for reference.
Mannheim Hauptbahnhof is an ICE hub on the Frankfurt-Stuttgart corridor. The Radisson Blu Hotel at Q7 27 is a short walk or taxi ride from the station.
The workshop day on June 9 was a separate, optional component ahead of the two-day conference. Bundle details are not separately disclosed by the organiser.
As the first in-person edition, a simultaneous virtual format is not confirmed by the organiser.
