Hi HN — I built OpenAdLibrary to address a transparency gap in native advertising.
Networks such as Taboola, Outbrain, MGID and RevContent don’t provide comprehensive public ad libraries. OpenAdLibrary currently indexes more than 1,000,000 native ad creatives from 36,000+ advertisers across 50 networks.
Rather than storing only screenshots, it follows each ad’s redirect chain to the advertiser’s final landing page and records how long the creative remains active. The dataset also includes 1.9 million captured landing pages and is refreshed hourly.
The library is free to browse without a credit card. There’s also a public API and a hosted MCP server for developers and AI clients.
I’d particularly appreciate feedback on the search experience, API and any additional transparency data that would be useful.
