DrupalCon Rotterdam 2026 Session Schedule

The future of Drupal UX isn’t more JS; It’s smarter HTML with HTMX.

Prerequisite

Bring a Drupal contribution idea - or use one of ours - and work through a practical AI-assisted workflow that turns it into a review-ready contribution designed to earn maintainer trust and accelerate the review process.

We can never get enough of SDC, the front-dev friendly API to implement and share UI components for Drupal.

LLMs are now table stakes in Drupal. Modules like AI, ECA, and a growing set of agentic tools make it trivial to wire a model into a site. What's not trivial is making that integration trustworthy enough to put in front of a real editor or site builder.

AI agents are becoming the new users of the web, and most CMSes are invisible to them. What if Drupal could speak the language of AI agents natively?

"Your AI can read every line of your code — but it has never watched it run. Until now."

Turn your Drupal issue queue into a smarter, faster workflow with open source coding agents that reduce maintainer workload and improve contribution quality.

Prerequisite

Workspaces is no longer only about staging content. It is becoming part of how Drupal can handle governed change across content, config, and AI-assisted workflows.

Prerequisite

Move your Drupal projects from AI experimentation to enterprise-ready implementation. This workshop provides hands-on experience deploying secure, agentic AI features and automated content workflows using curated, official tools.

Prerequisite

We are increasingly asking AI to fix our WCAG errors, but algorithms operate on probability, not empathy. If you are using AI coding assistants to write your front-end components, you might be shipping hallucinated ARIA labels and broken accessibility without knowing it.

Performance regressions are silent killers — they sneak in one commit at a time, and by the time someone notices, the debt is enormous. Gander, shipped with Drupal core since 10.2, gives us the tools to catch them at the earliest possible stage: the merge request.

In an AI-driven development world, speed is easy to gain but control is easy to lose. This session shows how to stay in charge of your code and your craft.

Prerequisite

AI coding agents are changing how we build software, but can they migrate a real production site to Drupal Canvas? We put it to the test on a live project and share what worked, what didn't, and what the numbers actually say.

Prerequisite

Confidence in shipping a Drupal-based product shouldn't take 6 days of GitHub runner time, only to be greeted by flaky tests in some of our 500+ jobs.

When AI writes the code, clean code becomes the developer’s most important job.

Prerequisite

Basic Drupal development knowledge
Experience reading and reviewing code
Some exposure to AI coding tools is helpful but not required

Target Audience

Your Drupal test suite is slow and it doesn't have to be. The test pyramid has been a cornerstone of software quality for decades, yet Drupal core has no formal guidelines instructing contributors how to write automated tests.

This session details the future roadmap for ECA, aiming to broaden its accessibility and impact within the Drupal community by making it usable for all users, regardless of technical expertise, and expanding its capabilities beyond just developers and site builders.

It finally happened! A CLI in Drupal core.

Prerequisite

None

Target Audience

Most interesting to developers and sysadmins

Outline

Join the Product Managers of the Drupal AI Initiative for the official update on Drupal's transformation into a production-ready Agentic CMS.

Canvas or Display Builder? Which one is the right tool for your job? And what may explode i if you install both?

Prerequisite

What happens when your migration source has 163 paragraph types — some containing entire pages of mixed HTML in a single field — and your destination architecture has 42 typed paragraph bundles? It's a fascinating transformation problem that invites you to rethink how migrations can work.

What if you could replace Solr with something that runs in the browser, costs almost nothing, and delivers better results out of the box? Scolta is an open-source search toolkit that does exactly that: client-side search powered by Pagefind, with an AI layer for query expansion and summaries.

You already know how to build an SDC. Now what if your agent knew how to build one too — then dropped it into a page, verified it rendered correctly in the browser, and asked you to review the diff?

The age of React.js is over. Web Components have arrived. Learn practical tips to building or reusing design systems with Web Component APIs and SDC.

Prerequisite

Developers should be familiar with SDC and JavaScript; expert knowledge is not required.

Target Audience

Content editors at the European Commission manage hundreds of websites in 24 languages. Every publication needs to be accurate, readable, and compliant with policy, and it needs to stay that way as policies change. Doing that manually across thousands of pages does not scale.

Building a complete Drupal site demands expertise across content types, taxonomy, menus, block configuration, and styling. What if a non-technical user could describe what they need in plain language and get back fully structured, styled pages, then refine everything through conversation?

What if the best AI chatbot is not a chatbot at all, but a constrained search engine?

Prerequisite

Basic understanding of:
Drupal content architecture
Search concepts (Solr, Elasticsearch, or similar)
General awareness of LLMs

Target Audience

Drupal 11.4 reduced database queries and cache i/o around 50% compared to Drupal 11.0 as well as various front end performance improvements. This session will explain how we got there and give you tips for applying these techniques to your own site.

Prerequisite

What image styles did for images, Drupal still has not really done for video.

This session shows how a modern Drupal 11 video architecture can close that gap with AV1, responsive sources, provider plugins, and production-ready engineering patterns.

Prerequisite

What if your Drupal site could talk to your project management, ticketing, CRM, email, calendar, voice assistant, and smart home — through one AI-orchestrated workflow? We built exactly that.
