GraalVM Community Summit

October 22-23, 2025, Zurich, Switzerland

Since its launch, GraalVM has seen significant growth and adoption — largely thanks to the invaluable feedback and collaboration from the community. To facilitate it further, we host the annual GraalVM Community Summit — an event that brings together our partners and members of the GraalVM community to discuss the project status and collaborate on its further direction. This year, it will take place in Zurich, Switzerland, on October 22-23.


This will be the fifth edition of the Summit, and it has been highly successful in gathering community feedback and promoting cooperation. Over the years, it has grown substantially, with last year's event featuring representatives from companies such as Alibaba, Amazon, Apple, BellSoft, Broadcom, Enso, Google, JetBrains, Microsoft, MicroDoc, Neo4j, Red Hat, SAP, Shopify, TornadoVM, as well as academia and several Oracle teams.


This event also has proved valuable for collaboration beyond the GraalVM ecosystem — participants get a chance to talk with framework teams, library maintainers, vendors, and other members of the Java ecosystem.


The Format and Agenda

The Summit is a two-day event with presentations and working group sessions. It will include talks on the GraalVM roadmap, its role in the Java ecosystem, recent and upcoming changes. Then, we will proceed with an unconference style, where participants propose topics and vote on what they would like to discuss. We also welcome community presentations—feel free to email us your proposal.
Some of the topics we plan to cover include:

  • How can we further drive community adoption of GraalVM?
  • What future directions would be most valuable for GraalVM users?
  • How can we further improve developer experience?
  • Community and governance
  • Your topic → feel free to suggest!
