Pricing Proof

Yes. Proof is a free, open-source plugin licensed under GPLv2 or later. The full core feature, sales notifications built from real orders, is available at no cost. The paid Proof Pro add-on adds product-review popups.

Yes. Proof is a WooCommerce extension and declares WooCommerce as a required plugin, so it will not activate without it. It needs WooCommerce 8.0 or later, WordPress 6.5 or later, and PHP 8.1. Notifications are built from your WooCommerce orders.

Only the buyer's billing first name and city. Surnames, emails, full addresses and order numbers never leave the server. When an order has no first name, Proof substitutes a word you choose (the default is "Someone").

No. Every popup comes from a real WooCommerce order with the status completed or processing. Proof never invents counters or demo data. When there are no qualifying orders, no script or widget is loaded at all.

Up to the 40 most recent orders with the status completed or processing from roughly the last 30 days. From each order only the first product name plus the buyer's first name and city are taken. The query runs at most once every five minutes and the result is stored in a transient.

No. The script is a small, dependency-free piece of vanilla JS loaded with defer in the footer. Order data is cached in a transient, so the store does not re-query on every page view. The popup is fixed to a corner, so it never moves other content or adds to Cumulative Layout Shift.
