CrystalConf 2023

Berlin & online

CrystalConf 2023 took place in Berlin on 23rd and 24th October 2023, in hybrid mode.

With a global community and contributions from people worldwide, Crystal has achieved a strong space in the programming world. To celebrate Crystal’s journey, users, developers, and contributors of our beloved language gathered to share their experiences.
