A promotional banner for “Fronteers Dark Mode”. In the background is a photo of the outdoor terrace of Cinema De Witt in Dordrecht, with people sitting, chatting, and enjoying food and drinks in a cozy, well-lit evening setting.

Join us on Friday, October 3rd, 2025, at Cinema De Witt in Dordrecht for an intimate evening of frontend talks and community vibes – from 4PM to after midnight.”
