How AI is used
Vaadin is a Java web framework for creating production-ready business applications. It supports the development of user interfaces using a unified Java stack, which may reduce the need for developers to switch between different frontend and backend languages.
The framework provides over 50 open-source UI components and conforms to WCAG 2.1 AA accessibility standards. For projects with specific regulatory requirements, these components support screen readers and assistive devices.
Vaadin also includes Vaadin Copilot, an AI-assisted visual editor for UI design, and a Modernization Toolkit for migrating legacy applications. Buyers should confirm which subscription tier is required, as certain components and automated testing tools are available only in paid plans.
