Which of these ads has actually survived?

The Meta Ad Library shows you every ad an advertiser is running and almost nothing about which ones are working. MurmAds reads the page you already have open and reports how long each ad has run, how many creatives the account is testing, and the spend Meta publishes — as the ranges Meta actually states.

Free tier · Chrome · reads only the Ad Library page · updated 24 August 2026

A range stays a range. Meta discloses EU spend and reach in bands. Every tool in this category quietly converts them into a single confident figure. MurmAds prints the band, because the midpoint of a wide band is an invention wearing the typeface of a measurement.

What it reads

  • How long each ad has been running, from the dates on the page. The closest public signal there is that a creative works, because advertisers stop paying for ones that do not.
  • How many creative variants an advertiser is testing at once — the shape of a testing budget, visible without a single estimate.
  • Spend and reach, exactly as Meta discloses them.
  • A scaling signal, with its method printed beside it rather than behind it.

What it refuses to tell you

Every MurmTools extension refuses at least one number that other tools invent. This one refuses to turn a disclosure into a figure.

  • No single spend number. Where Meta publishes a band, the band is what you get. No midpoint, no “approximately”, no confident euro amount derived from a range hundreds of thousands wide.
  • No performance you cannot see. Nobody outside the account knows the ROAS, the CPA or the conversion rate. Duration and variant count are evidence; they are not results, and are not dressed as them.
  • No archive of deleted ads. An ad that is gone from the page is gone from the panel. Tools that show you deleted ads crawl and store them on a server; this reads what is in front of you, and says so.

Why it has no ad database

Because a database is a different product with a different price and a different set of promises. An archive means a crawler, a server, and a copy of other people’s advertising held indefinitely. MurmAds reads the page in your browser at the moment you click it, which is why it needs no account, keeps nothing about you, and can be free to try. It is a smaller claim, honestly kept.

Saving what you find

Ads you want to keep go onto boards, with tags and filters, and Pro lays them out on a canvas so a competitor’s whole creative rotation can be read at once. The free tier keeps fifteen ads and one board — enough to work with, not a demo that stops mid-thought.

Free to use, Pro at EUR 9.99/month or EUR 79/year. Three permissions — activeTab, scripting, storage — plus the Ad Library pages it runs on and extensionpay.com for the licence check.

Questions

How do I see how long a Facebook ad has been running?

Open the advertiser’s Ad Library page and click the icon. MurmAds reads the start dates Meta publishes and reports each ad’s duration, longest first.

Can it show me a competitor’s ad spend?

Only what Meta discloses, and only as the range Meta states. It will not convert a band into a single number.

Does it show deleted ads?

No. That needs a crawler and a server; MurmAds reads the page you have open. Tools with an archive can do this and charge for it.

Is it free?

The reading is free, with fifteen saved ads and one board. Pro adds unlimited saves, the canvas, bulk download and advanced filters.
