Ad Library Chrome extensions, compared

The Meta Ad Library is free, official and comprehensive, and it is also missing almost every feature you would want. You cannot sort. You cannot export. You cannot save anything. The numbers that would tell you whether an ad is working are hidden behind a panel on each individual ad.

A whole category of Ad Library Chrome extensions exists to patch those gaps. The names are confusingly similar — a browser search returns a dozen products all called some arrangement of "ad library", "downloader" and "finder" — but they split cleanly into three jobs. Work out which job you have and the choice becomes obvious.

Job one: downloading creative

The largest group. Install one, click once, and a download button appears on every ad so you can save the video or image file directly. Some also copy the ad text and take a screenshot of the landing page.

Extensions that do this: AdLibNote, Ad Library Cloud, Ad Library Downloader, AdGrab, and a long tail of similar tools. Several have tens of thousands of users, which tells you how common the need is.

Use one if you brief designers, keep a reference folder of competitor creative, or need a copy of an ad before it disappears from the library.

What they will not tell you is whether any of it worked. A download button is indifferent to whether the ad ran for two days or two years.

Job two: saving and organising

A step up from downloading. These save ads into boards in a web app, tag them, let a team share and comment, and keep the creative permanently so it survives Meta removing the original.

Extensions that do this: Foreplay, MagicBrief, Denote, Swipekit. The extension is typically the free front end for a paid platform, with the subscription starting around fifty dollars a month.

Use one if a creative team needs a shared swipe file with a real workflow rather than a folder of downloaded files.

What they will not tell you is, again, performance. A well-organised library of ads is still a library of ads you have no data on.

Job three: reach and estimated ad spend

The smallest group, and the newest, because the data only became available when EU transparency rules landed. These read the reach figure Meta publishes for every ad delivered to the European Union and convert it into an estimated budget, shown on each ad card.

Extensions that do this: CompetitionAds (ours), AdLibSpy, AdSpend Analyzer, Ad Library Accelerator, AdManage AdScan. Coverage and presentation differ; the underlying public data does not.

Use one if you want to know which of a competitor's ads carry the real money — the question the other two categories cannot answer at all.

What they will not tell you is anything about ads that never ran in Europe. No published reach means no estimate, for every tool in this group equally.

The three jobs at a glance

Platform coverage and features change often in this category; check the current Chrome Web Store listing before you install.

Platform coverage is where the categories really differ

If you only work on Meta, coverage is a non-issue — every extension here handles Facebook and Instagram, because that is what the Ad Library contains. The picture changes if your research spans more platforms.

The saving tools are the ones that went multi-platform. Because they are the front end for a wider service, they generally also pull from the TikTok Creative Center, the LinkedIn ad library and YouTube, so a single board can hold creatives from all of them. That breadth is the main thing the subscription buys.

Downloaders and spend tools stay on Meta. For the spend group that is not a choice: no equivalent public reach data exists for TikTok or LinkedIn, and Google publishes its own transparency centre with a different structure entirely. Any Ad Library Chrome extension promising spend figures across every network is describing an estimate built on something other than published data.

How to choose, quickly

Check which job it does before anything else

Listing copy for an Ad Library Chrome extension is written to sound comprehensive, so read for the verb. "Download", "save" and "spend" are three different products. An extension that leads with creative organisation is not going to give you budget data, whatever the feature list implies.

Check whether the extension is the product

Some extensions work immediately. Others install, then ask you to create an account and start a trial before showing anything. Both models are legitimate, but the second means you are evaluating a platform, not a browser tool, and should price it accordingly.

Check the permissions

An Ad Library extension needs access to facebook.com. That is the whole requirement. Any request for access to all websites, browsing history or your own ad accounts deserves a hard look at what the tool is doing with it — free products still have business models.

Check the ratings honestly

This category has a lot of listings with very few reviews, and install counts that do not correlate with quality. Read the recent one-star reviews specifically: in a category that depends on scraping a page Meta keeps changing, the common complaint is that the extension quietly stopped working.

Why so many of them break

Worth understanding before you commit to any of these. Every extension here works by reading Meta's own page structure, and Meta changes that structure regularly without warning. When it does, extensions across the category stop rendering until each developer ships a fix. This is why so many listings carry a note about restarting your browser after an update, and why update recency is a better quality signal than install count when you are choosing between two similar tools.
