Vaadin 24.4: Introducing the code-first AI-powered UI editor and React seamlessly integrated into the Vaadin platform

Vaadin 14 Extended Maintenance

Secure the future of your application

Vaadin 14 is reaching the end of life

After 5 years after its initial release, Vaadin 14 will reach its end of life on August 14, 2024. Your Vaadin 14 application will no longer receive:

  • Critical security fixes and patches
  • Browser and JVM compatibility fixes
  • Feature updates
  • Bug fixes

At best, this could just lead to some downtime for your users and extra work for your development team.

At worst, this could result in compromised applications or confidential data being stolen by malicious actors.

Extended Maintenance (EM) allows you to maintain the safety and functionality of your Vaadin 14-based applications for up to 10 more years.

Extended Maintenance for V14

Continuous updates give you peace of mind and ensure your V14 application's continued success. Worry less about browser compatibility, bugs, and, most importantly, the security of your user data.

V14 Extended Maintenance is available for purchase for Prime and Ultimate subscribers only.

Types of Maintenance Tasks

The Vaadin support team performs two types of maintenance tasks to keep Vaadin 14 secure and up-to-date:
