Method
Sources, disclosure, and comparison rules
Adflex publishes this page. To reduce bias, the comparison gives both products explicit strengths and limits, links to official sources, and avoids unsupported performance claims.
Official sources checked: Meta Ad Library, Adflex Mega Search, Adflex pricing, and Adflex Enterprise API.
We do not treat advertised database totals as directly equivalent because vendors can differ in sources, retention, counting, and duplicate removal. Purchase-critical details should be confirmed on the current official pages.
