Magento.

The e-commerce platform that truly belongs to you.

The freedom to build, without compromising on performance.

Magento Open Source is the foundation on which hundreds of thousands of online stores have been built around the world. Free, open source, and modular — it is the e-commerce platform that truly belongs to you, from its code to its roadmap. No licence to renew, no locked features, no dependency on a publisher to evolve: just a powerful platform, built by and for people who have decided to take e-commerce seriously.

It shares the same technical foundations as Adobe Commerce, without the advanced enterprise features — the native B2B suite, Content Staging, Customer Segments, or the RMA module. For projects that do not require these capabilities, it is a solid, proven base with no licence cost. No recurring fees are imposed, the source code is fully accessible, and the global community has been actively contributing to its evolution for decades.

Magento is a professional platform, capable of handling catalogues with thousands of references, multisite and multilingual architectures, ERP and PIM integrations, and significant traffic spikes. Whatever you ask of it, it can deliver — provided it is built properly.

Magento Open Source + Hyvä.

The Magento community.

Every year, we actively participate in OpenGento weekends — the French non-profit association dedicated to the Adobe Commerce and Magento Open Source community.

Founded in 2014, OpenGento brings together developers, agencies and Magento enthusiasts every year for a hackathon weekend: talks, collaborative projects, conferences, and an atmosphere that feels as much like a developer camp as an annual unmissable gathering. Our teams have participated every year since 2023. In 2024, the edition was hosted by us, in Alsace, in Sélestat — a particularly proud moment for the team. A unique format, in a privatised villa, designed to let the best ideas emerge in a setting built for sharing.

It is also in this spirit that Meet Magento France was born — the reference event for the Adobe Commerce community in France, supported by Adobe as a Platinum sponsor. At the inaugural edition in March 2025, Cannelle and Olivier co-organised the event alongside our peers, and ATI4 was a Gold sponsor. Joris, co-founder and CTO, took to the stage alongside Baptiste Bataille to talk about the Alain Afflelou project and share the behind-the-scenes of an emblematic B2B project. The second edition will be held on 25 June 2026 in Paris — and we’ll be there again!
