An ad-library extension that ranks ads by how long they have been running.
AdSpyfy is a Chrome side-panel extension for the public Meta Ad Library and the Google Ads Transparency Center. It reads the results page you already have open, records how many days each ad has been live, and sorts longest-first — because an advertiser who keeps paying for the same creative for 300 days is telling you something a three-day test is not.
Days-running sort
Every captured ad carries its run length. Sort longest-first, or flip to recently-seen to watch fresh launches. Lifecycle labels (Testing, Running, Scaling, Proven, Killed) come from duration and active status.
Search your harvest locally
The Ad Library will not let you search inside the results you already loaded. AdSpyfy filters your captured set as you type: include terms, -word exclusions, semicolon phrases, advertiser, lifecycle, source.
Swipe file with notes
Save winners to boards with tags and notes. Your research stays in your own browser — nothing is uploaded to us, because there is no server to upload to.
Bulk creative export
Download captured creative as a single ZIP, or export the harvest to CSV and JSON for the tools you already use.
Why this one, when ad finders already exist
Most "ad finder" extensions do one thing: they show you ads that exist on the page. AdSpyfy is built around a different question — which of these ads is worth studying? — and answers it with the only honest public signal available: duration and active status.
| Typical ad finder | AdSpyfy | |
|---|---|---|
| Primary signal | Ads detected on page | Days each ad has been running, plus active status |
| Sorting | Page order | Longest running, shortest running, recently seen, impression rank |
| Search | None inside captured results | Full local query syntax over text, advertiser, lifecycle, source |
| Sources | Usually Meta only | Meta Ad Library + Google Ads Transparency Center in one harvest |
| Storage | Often a vendor cloud | Your own browser, no uploads |
| Price | Freemium or subscription | Free tier with real capture; lifetime unlock for swipe file and AI extras |
It works with both libraries you already have open:
- Meta Ad Library (
facebook.com/ads/library) — capture, run lengths, lifecycle labels, reach and spend ranges where Meta publishes them. - Google Ads Transparency Center (
adstransparency.google.com) — the same harvest flow, tagged Source = Google.
No Meta login is used, nothing is crawled in the background, and there is no performance data that Meta and Google do not publish — run length and public fields only. The docs list every limit in plain language.
Install in two minutes
AdSpyfy installs as an unpacked Chrome extension — no store review waiting period, no account:
- Grab the ZIP from the install section and unzip it somewhere permanent.
- Open
chrome://extensions, enable Developer mode, click Load unpacked, select the folder. - Open the Ad Library, press Alt+Shift+A, and scroll or start auto-scroll.
The docs cover every filter, the search syntax, lifecycle labels, exports and MCP connection to Claude or Cursor. Building a filtered Ad Library link instead? Use the URL builder.
