Apache Groovy events you shouldn't miss!

GR8Conf EU
Copenhagen, Denmark

Groovy, Grails, and related technologies have seen astounding growth in interest and adoption over the past few years, and with good reason.

GR8Conf is a series of conferences founded to spread the word worldwide. The 2018 GR8Conf Europe is celebrating its 10th year, and it's expected to be a blast. As in 2017 the conference had a DevOps day, this year DevOps topics will be mixed with the rest of the topics.

GR8Conf is an independent, affordable series of conferences and covers All Things Groovy

GR8Conf US
Minneapolis, MN, USA

GR8Conf US is the equivalent of GR8Conf EU, but yet different. It has its own organization and its own crew.

The goal is the same. It is founded to spread the word about the fantastic Groovy technologies and community.
