WordPress plugin Gravity Forms is a powerful tool that allows users to create advanced forms on their WordPress sites, collecting, managing, and sharing data to improve their business. It was created by Carl Hancock, Alex Cancado, and Kevin Flahaut in 2008 as a solution to the need for more complex contact forms. The plugin features an intuitive drag-and-drop interface with conditional logic, custom HTML insertion, and secure payment processing capabilities. It powers over 5 million WordPress websites globally and offers various integrations with other apps like Zapier for automation workflows.
