What is Gravity Forms?

Gravity Forms is a powerful and feature-rich form builder plugin for WordPress, designed to create complex forms with ease. It offers a drag-and-drop interface, allowing users to build custom forms without the need for coding skills. The plugin supports a wide range of form types, including contact forms, surveys, registration forms, order forms, and more.

Key features of Gravity Forms include advanced field options such as text, dropdowns, checkboxes, file uploads, and calculations. It also supports conditional logic, enabling the display or hiding of form fields based on user input, which enhances form customization and user experience.

Gravity Forms integrates with popular third-party services, including email marketing platforms (e.g., Mailchimp, Constant Contact), payment gateways (e.g., PayPal, Stripe), and CRM systems (e.g., Salesforce), allowing for seamless automation and data management. The plugin also offers multi-page forms and file upload capabilities, making it suitable for more complex workflows.

Why Use Prosopo Procaptcha With Gravity Forms?

Prosopo is a specialist bot and agent trust platform. Every verdict traces to a rule the operator authored, on a proprietary detector with an open-source client stack. UK-incorporated, EU-processed, GDPR-native. It stops the abuse patterns WordPress form spam alone doesn't cover:

• Scraping
• Denial of inventory
• Credential stuffing
• Account takeover
• Click through rate/ad fraud
• Ticket scalping
• Black friday automation (and more general sale automation)
• Phishing attacks
• Loyalty programme automation

Prosopo also keeps visitor data out of Google's data controller chain for reCAPTCHA telemetry — the 2026 reCAPTCHA terms change reclassified Google as controller rather than processor.
