Overview
Devoxx Belgium 2027 is a five-day developer conference held at Kinepolis Antwerp in Antwerp, Belgium, from 4 to 8 October 2027. It brings together developers, architects, builders, and innovators to explore the future of software engineering. The event is organized under the theme "FROM DEVELOPER TO BUILDER", reflecting a shift in which developers increasingly create software with the help of AI agents, autonomous workflows, and advanced coding assistants.
The program covers Java, AI, cloud, architecture, and the broader craft of building software. Topics mentioned include multi-agent architectures (A2A), the Model Context Protocol (MCP), local LLM clusters, GPU inference, next-generation Java AI libraries, and Spec-Driven Development. Java 29 is expected around the time of the event, and the organizers highlight concurrency, performance, cloud-native development, and AI integration as key areas of Java's evolution.
Who should attend
The conference is aimed at developers, architects, engineering leaders, and anyone interested in how intelligent systems change the way software is designed, built, reviewed, and maintained. The organizers describe it as a place to exchange ideas with a large community of developers, speakers, sponsors, and technology leaders.
Tracks
The 2027 program is organized into eight tracks:
- Agentic Engineering & Tooling: multi-agent systems, tool use, evals, and shipping AI beyond the demo.
- Java Language & Platform: Project Loom, Leyden, Valhalla, Panama, and the evolving JVM.
- Cloud Native, Data & Infrastructure: Kubernetes, platform engineering, vector databases, model serving, and GPU orchestration.
- Architecture & Modernization: designing for agentic workflows, event-driven systems, and legacy transformation.
- Security, Trust & Compliance: guardrails, prompt injection defense, model governance, and supply-chain security.
- Development Practices: methodologies and better practices for getting work done well.
- People, Practices & Career: leading teams, engineering culture, and career resilience.
- Mind the Geek: topics such as robotics, biological computing, cybernetics, new tools, and future technology.
Format
The week is split into two kinds of days. Monday and Tuesday are Deep Dive days with three-hour sessions, hands-on labs, and lunch talks, where attendees leave with working code. Wednesday to Friday are Conference days featuring keynotes, 50-minute talks, hands-on labs, and 40-minute lunch talks across many rooms. A Combi pass covers both the Deep Dive and Conference days.
Evenings include Birds-of-a-Feather (BOF) sessions, user group meetups, and informal community time. Indicative timings show registration opening on the first morning, the exhibition floor opening on the second day, an opening keynote on Wednesday, a closing keynote on Friday, and a Devoxx Movie on Friday evening. The organizers note that the detailed schedule will follow once the program is final.
Recordings
Talks are recorded and published on the Devoxx YouTube channel, so attendees and others can watch sessions they missed.
Registration and key dates
Registration opens on 16 August 2027. The Call for Papers opens on 1 June 2027 and closes on 16 July 2027 at 23:59 CEST for those who want to speak.
