Neos Conference 2025
19.06. - 21.06.2025

Welcome to Neos Conference 2025!

Same procedure as every year. Robert rings in the Neos Con and gets us all in the mood for two exciting days in Karlsruhe. 

Bernhard is about to present a relaunch project, featuring SSO with shops of all sizes, personalized, business-related content and functionality and focus on being future-proof. And since it was built with Neos 9, there is quite some first-hand experience to be shared on that part as well. In this case study, he wants to show why Neos is a great choice to build content-based applications with, how easy it was to integrate with an SSO provider and especially his experience with launching the community's first project on Neos 9.

There are various ways to ensure code quality in PHP projects, but there are specific tools in the Neos ecosystem that focus on validating nodetypes, Fusion rendering and best practices in a Neos project. Fiach will guide you through the various tools and explain the benefits and how to get started.

In this presentation, you learn how you can implement your IT projects efficiently with a lightweight, practical approach of requirements engineering. It works by thinking from the end: Who needs which requirements for which purpose? The effort estimation in Use Case Points, architectural design, technology choice, acceptance test, this all is based on the requirements. The recommended approach is illustrated by an example.

The biggest issue for our society and the upcoming centuries is the global warming and climate crisis. The internet has approximately 10% of total electricity consumption. We as developers can make a difference and build web applications that can save our planet.

Stop building AI features that feel like Gmail's generic "Help me write" button—where editors lose control and get bland, cookie-cutter content. Instead, discover how to create AI agents that work as true co-pilots, where editors define the brand voice, set the rules, and maintain complete editorial control. We'll show you how to develop a Brand Guard agent with n8n that automatically checks content against your style guidelines, suggests improvements, and lets editors accept or reject changes with one click. Learn how to turn Neos into an AI-native platform that amplifies editor creativity and productivity.

Martin and Bernhard present a solution to autogenerate machine and human readable OpenAPI documentation directly from top notch & type safe PHP code. This speeds up our development process and also allows full static analysis on both sides of the API.

In this talk, I will share our experiences implementing a large-scale project based on the Neos 9 beta which started out in the fall of 2023. I will give a brief analysis of our decision-making process for choosing Neos 9, show what went well and present the promises that have not yet been fully delivered in practice. The main part of the presentation focuses on Neos 9’s data architecture, with special emphasis on NodeTypes, Nodes and their serialization through DTOs, as well as the associated caching strategies. I will highlight the challenges we faced during implementation, talk about performance issues and limitations and publishing complications, and how Beta 16 finally brought the decisive breakthrough. In the second part I want to talk about taking the new CR to the next dimension by replacing the current relational database with a graph-database, specifically Neo4j, to make even better use of the magic that is graph data structures and explain the resulting benefits for existing functionalities as well as possible future applications, like the idea of a SpaceTimeGraph to maintain all states and changes within the cr simultaneously in one projection. This talk is aimed at developers and architects who want to know if it's feasible to use Neos 9 and gain deeper insights into the powerful graph functionalities of Neos 9 and harness their full potential for their own projects.

Last year during the DrupalCon in Portland Dries shared big news: we are about to build a new Drupal CMS! It will be a no-code solution suitable for marketers that will not require coding in order to be set up. The idea resonated massively with the community - hundreds of people signed up as potential volunteers that very day. At that point we didn't have roadmap, we didn't have a clear idea about the user experience or detailed overview of the functionality to be included in the first release but what we DID have was the support of brilliant people ready to roll up their sleeves and get to work. Today I want to share with you the insight on our journey from the point of Leadership Team member and introduce you briefly to the Drupal CMS - product built by our community for the world of Open Web!

Why did we build Sevensite, and what challenges did we face? In this talk, we share our motivation, the obstacles we encountered, and how we overcame them. Get an exclusive behind-the-scenes look at the technical decisions, scalability solutions and the making of our customizable Neos-SaaS platform!

Let's end the first day full of neos and head into the evening relaxed. See you at the social event! 

Welcome to day 2 of Neos Con! 

Did your site just went viral on social media, had your product pitched on Shark Tank or did your festival site just launch its ticket sale? In these scenarios, no site survives its first contact with production traffic. That’s why it is useful to know in advance how your project will behave at scale under production workloads. In this talk, I will talk about how to implement high-scale load-testing with Open Source tools like Grafana K6. Along the way, we will cover how to mimic user behaviour realistically, how your testing infrastructure should look like to simulate 10-100k simultaneous users and even how you can incorporate regular load tests into your CI/CD pipeline. Real-world case studies included.

Put aside what you know about the core of the old content repository and brace for Neos 9. Over the last year we further refactored publishing, projections and introduced various new concepts. I’ll tell you all about it, what you can extend and what we might be able to archive in the future.

In this talk Sebastian will explain why and how he converted a React based backend module to HTMX and integrated it into the Neos 9 core. Learn about the benefits in regard to extensibility, build stacks, maintainability and how you can get started with your first HTMX based backend module.

A few years ago, Passcreator planned to hire locally in Munich but ended up hiring across Europe, leaving us with too much office space. In 2024, we downsized and equipped every employee with VR headsets. In this talk, I’ll share our experience using VR in daily work—successes and challenges.

Software development is about efficiency and creativity. In this talk Daniel explores how tools like GitHub Copilot and Cursor transform workflows, automate tasks, and let you focus on delivering smarter solutions and exceptional code.

Have you ever considered what would happen when a popular open source package is abandoned?
Now, what about when that package is one of your essential dependencies?

This scenario is not some abstract scenario for a far away future. Projects get abandoned every day and your dependency might be next... But you can help!
Come & listen to some tales of an accidental maintainer and learn about what you can do to help try and prevent these situations from getting out of hand.

HTML is the foundation of the web. It seems easy to write, yet, there are many pitfalls that we as developers can stumble into – leading to invalid and inaccessible websites. In this talk, i will equip you with all the tools necessary to confidently write a robust HTML base for your websites.

A Content Management System, like every software out there, has an impact on the environment. The point is: we usually don't see the fumes and the dirt that it causes behind the polished web frontend or the fancy administration interface. But it's there, and we all should be aware of it. In this talk, we'll discuss why the IT is such a significant contributor to the worldwide carbon emissions. We'll talk about why the insatiable hunger for more and more computational resources even gets worse, and what every one of us can do against it - starting with your favorite CMS.

Members of the Neos core team discuss where the journey with Neos 9 will take us next.
