Gravity Forms is a WordPress plugin used originally for contact forms, but in a more general sense, it allows site owners to create forms to collect information. Gravity Forms can be used for contact forms, WordPress post creation, calculators, employment applications and more.
Written in PHP, Gravity Forms uses many WordPress built-in functions and features to power its form builder. It also uses the same MySQL database system as WordPress, but stores all forms and entries in its own tables.
Gravity Forms is open source and GPL licensed. All of the code included is unencrypted, and easy to modify. We’ve added in tons of hooks and filters to be able to customize Gravity Forms to your hearts content.
