On March 26, 2026, the EO2S — Ecommerce Open Source Summit will bring together the open-source e-commerce ecosystem in Issy-les-Moulineaux / Paris, with Friends of Presta behind the event. It is positioned as a full day of exchanges around conferences, workshops, round tables, and networking. :contentReference[oaicite:0]{index=0}
What makes this edition especially interesting is the context.
This is not just another community meetup. It comes at a moment when the European open-source commerce landscape is evolving fast, with stronger attention on topics like sovereignty, AI in e-commerce, security, and the growing convergence around PrestaShop and Sylius. :contentReference[oaicite:1]{index=1}
For developers, agencies, module publishers, merchants, and solution partners, events like EO2S matter because they concentrate the conversations that shape what comes next: architecture choices, ecosystem direction, partnerships, and the future of open-source commerce in Europe. :contentReference[oaicite:2]{index=2}
If you are close to the PrestaShop ecosystem, this is clearly one of the events to watch.
