Open Source CMS 26 conference

A vendor-neutral conference for the open source CMS community

October 20–21, 2026 | Utrecht, Netherlands

Join the first annual Open Source CMS Conference - a vendor-neutral event bringing together the global open source CMS community to share ideas, tools, and best practices for building better content management systems.

Tired of impersonal, overwhelming tech conferences? Open Source CMS 26 is different: a unique mix of hands-on masterclasses, expert talks, interactive discussions, and real networking with the people shaping open source CMS today.

We're hosting it at Stadsklooster Utrecht — a former Roman Catholic St. Antonius Church that has been turned a unique and character-filled meeting venue. A great place for learning and networking.

What is the Open Source CMS conference?

It's what's been missing for the open source CMS community — an international gathering bringing together digital leaders to tackle the challenges shaping open source CMS today and in the years ahead.

Expect friendly mix of vendors, agencies, analysts and customers from Europe and North America who get together to learn, network and talk about what really matters when it comes to creating better digital experiences right now and for the foreseeable future.

Who’s joining us?

Here's a look at some of the people and organizations already on board.

At the conference you can learn from practitioners from Albert Heijn, City of Antwerp and several others.

Among the open source projects and platform companies attending are Drupal, Joomla, Pantheon, TYPO3, Umbraco, Webiny and WordPress. As you can see, it’s not just the usual vendors, but also from the larger ecosystem.

Bringing perspectives from the hosting and infrastructure side are Kinsta and mittwald. Both have extensive experience supporting organisations and agencies working with open source CMS platforms at scale.

On the agency and consulting side you can meet b13, Crowd Favorite, MaxServ, Punkt.de and XWP. Talk to them about what happens “when the rubber hits the road” and they’ll share what it actually takes to get a project across the finish line.

Among the analysts joining us are Matt Garrepy from CMS Critic and our host Janus Boye from Boye & Co in Denmark.

Thanks to everyone who has already made the commitment to learning and networking. We’ll keep this list updated as we get nearer October.

Venue

This year’s conference will take place at Stadsklooster Utrecht - a former Roman Catholic St. Antonius Church turned cultural venue where art, culture, and reflection come together, with a strong focus on the local community.

It's located at Kanaalstraat 198 in Utrecht's Lombok neighbourhood, and rents out several distinct spaces for presentations, meetings, and events. A unique, character-filled spot instead of a typical conference venue - a great place to build the day around.

What more can we say? Utrecht is easy to reach by train and is also a short trip from Amsterdam Airport.
