Description

The Gravity Booster Antispam addon displays a verification form before showing the Gravity Form to the visitor, filtering submissions by keyword with support for Chinese, Spanish, Arabic, and Hindi, by e-mail domain with allowlist and denylist, and by user role in WordPress. Designed for those already using Gravity Booster, the extension adds password protection, hides forms from unauthenticated visitors, and configurable age-range verification.

How to Download Gravity Booster Antispam

The Gravity Booster Antispam is available for download on this page. After downloading the .zip, click Plugins > Add New > Upload Plugin in the WordPress dashboard, choose the file and activate. Note that the plugin requires Gravity Booster to be installed and active to work.

With configurable rules per individual form, Gravity Booster Antispam allows you to segment protection according to each context’s risk: a public contact form may use only the keyword filter, while a sign-up form with sensitive data combines domain verification, role restriction, and password-based identity confirmation. Teams managing multiple Gravity Forms under Gravity Booster gain detailed access control without relying on external captcha services.
