User Interface (UI) frameworks are libraries of code, design elements, and components that help web developers create user interfaces with consistent structure and behavior.

They provide responsive grid systems, pre-built visual and interactive components, layout utilities, styling conventions, and integration tools that streamline development, ensure cross-device compatibility, and reduce the need to write UI code from scratch.

The following list shows the user interface frameworks ranked from 26th to 50th out of 64 tracked.
