Developer Network™ 
The Joomla! Project is pleased to announce the availability of the first Joomla 6.0 Alpha for testing.
What is this release for?
There are two main goals for Alpha releases:
- Providing developers with the basis to test their extensions and reporting any issues well before the final release
- Allowing users to discover the new features introduced to Joomla 6.0.
For a complete list of known backward compatibility issues for version 6.0, please see Potential backward compatibility issues in Joomla 6.0 on the documentation site.
What is this release NOT for?
This alpha version of Joomla 6.0 is not suitable for production sites. It is for testing only.
Where to get it?
To always use the latest build of Joomla 6, we invite you to use the nightly build packages (updated every night).
To make it easier for newcomers, you can launch a free Joomla 5 website for testing at launch.joomla.org.

What are the plans for Joomla 6.0?
Currently, we’re at the start of the journey of Joomla! 6.0. There are several projects which, with your help, could become part of Joomla! 6.0, if they are release-ready before the first beta is released on August 19th 2025.
- Healthchecker
- SEO
- Migration tool
We are at the beginning of the development of Joomla! 6.0, we have more than two months to add new features. If you have any idea for new functionality, feel free to discuss it on GitHub.
Be aware that these features are not release-ready yet, and it depends a lot on testers and feedback if they make the cut.
To learn more about our development strategy, please read this article.
How can you help Joomla 6.0 development?
To help ensure the 6.0 release and our major features are “production-ready”, we need your help testing releases and reporting any bugs you may find at issues.joomla.org.
Most of all, we encourage extension developers to roll up their sleeves, seek out bugs and test their extensions with Joomla 5.3 and communicate their experience.
Where can I find documentation about Joomla 6?
We encourage developers to help write the documentation about Joomla 6 on docs.joomla.org and manual.joomla.org to help and guide users and other extension developers.
A JDocs page will help developers to see the existing documentation and the documentation still needed.
We invite you to check it regularly, update it and provide the missing content.
