Why I Built This
Reveal Ad Spend is a free side project of Pantheon, an ad research tool. Meta already publishes the EU reach of every ad delivered in Europe, but checking it means opening ads one at a time and copying numbers by hand. The extension puts that number on the page, so anyone researching Meta ads can compare competitors in minutes, for free.
