7 Free Facebook Ad Analyzers (2026): Which One Answers Your Question?
Pick the free analyzer by the question you're asking. "Why isn't my live ad selling?" needs a tool that reads your results. "Is this draft any good?" needs a creative scorer. "Is my whole account too samey?" needs a diversity audit. All seven below are free, and five of them don't even need an account.
For a live ad that isn't selling
- SellTheClick ad analyzer
- Meta's opportunity score (setup, not creative)
For a draft before launch
- AdAmigo Roast My Ad
- Adverdly
- Alison.ai Preflight Plus (video)
For your whole account
- Triple Whale Creative Diversity Audit
- Knowlify Ad Creative Audit
For a batch of new versions
- SellTheClick similarity checker
Free Facebook ad analyzers have quietly become one of the most useful things in paid social. Several ad tools now give away a real piece of their product to show you how they think. The catch is that they all answer different questions, and the names don't tell you which. "Ad analyzer", "ad audit", "roast", "preflight" and "creative score" can mean anything from a checklist to a proper read of your numbers.
We make one of the tools on this list, so we stuck to what each vendor publishes about its own tool, checked on October 23, 2026. We describe what each one takes in, what it gives back, and where it falls short.
The comparison at a glance
| Tool | What you give it | What you get back | Account? |
|---|---|---|---|
| SellTheClick analyzer | Ads Manager numbers or a screenshot, plus the ad | Where the ad breaks: before the click, after it, or at the price | No |
| SellTheClick similarity checker | 2 to 20 images | Which versions are near-duplicates | No |
| Triple Whale audit | Your website URL | Diversity score across 6 dimensions, up to 80 live ads | No |
| AdAmigo Roast My Ad | An ad image and its text | Performance score, strengths, weaknesses, fixes | No |
| Adverdly | One creative | Scores on 8 dimensions as a PDF (2 free analyses) | No |
| Alison.ai Preflight Plus | A video | Score against Google's ABCD and Meta and LinkedIn best practices | No card, no ad account |
| Knowlify Ad Creative Audit | 3+ ads (copy and/or up to 8 images) | Diversity score across 6 dimensions, fixes for the weakest 3 | No |
| Meta opportunity score | Nothing, it's in Ads Manager | 0–100 score and recommendations for your setup | Your Meta account |
That's seven tools if you count SellTheClick's two checks as one product, plus Meta's built-in score as a bonus.
1. SellTheClick's free ad analyzer and similarity checker
Full disclosure: this is ours. It's here because it does the one job the others on this list don't. It starts from your results.
The analyzer takes the numbers from Ads Manager (spend, impressions, clicks, purchases) or a screenshot, plus the ad itself. It tells you whether the ad is losing people before the click, after the click, or at the price, and reads the hook, angle, offer and call to action. Your CTR, CPM and CPA are compared with Triple Whale's published medians, with CPA matched to your industry. Every number is labelled as measured, benchmark or computed.
The similarity checker takes 2 to 20 static images and flags the ones that are likely to be treated as the same ad, using a picture match (CLIP) and an AI read of what each ad says.
Where it falls short. Meta only. The similarity check doesn't do video. It doesn't give a single creative a "score out of 10", which some people find useful as a quick gut check.
Try the analyzer or the similarity checker. No account needed.
2. Triple Whale's Creative Diversity Audit
You enter your website URL. Triple Whale finds your active Meta ads in the public Ad Library, analyses up to 80 of them, and tags each across six dimensions: themes, formats, copy angles, creators, hook styles and personas. Each dimension is scored out of 10 for how many distinct variations show up, and the overall score is the average. You get recommendations by score tier and a view of every ad it analysed.
The neat part is that it needs nothing from you except a URL, so you can run it on competitors too.
Where it falls short. It only sees live ads and scores variety, not performance. A very varied account can still be full of ads that don't sell. Triple Whale says the report is completely free, with no card and no trial.
3. AdAmigo's Roast My Ad
Upload an ad creative and Roast My Ad analyses the image and text, assigns a performance score, highlights strengths, flags weaknesses and suggests improvements. AdAmigo says it's free with no login and no cap on uploads, and that it doesn't connect to your ad account. It's optimised for Meta ads, with insights for Google Display and TikTok.
Where it falls short. It judges one creative on its own merits. It can't tell you that your five drafts are the same idea, and it doesn't see your results. It's a pre-launch read.
4. Adverdly
Adverdly gives you 2 free analyses with no account and no credit card. Each one produces a scored PDF across eight dimensions: hook and attention, visual hierarchy, messaging and copy, persuasion and psychology, call to action, platform and format fit, offer-creative alignment, and brand and trust signals. Each gets a score from 1 to 10 with reasoning and suggestions. Paid plans start at $9 a month.
Where it falls short. Two free analyses go quickly. Like Roast My Ad, it scores a creative on its own rather than against your results.
5. Alison.ai Preflight Plus
Preflight Plus is Alison.ai's free entry point, and it's built for video. It scores a video against Google's ABCD framework and Meta's and LinkedIn's creative best practices. Alison says there's no credit card, no connected ad account, and results take about 30 seconds.
Where it falls short. Best-practice checklists catch the basics, like a late brand reveal or a missing hook in the first seconds. They can't tell you whether your audience will care. Alison's paid plans don't list prices.
6. Knowlify's Ad Creative Audit
Knowlify's audit is the closest free alternative to Triple Whale's, but you feed it the ads yourself. Paste the copy from at least three ads, upload up to eight images, or both. It returns a creative diversity score out of 10 and scores for six dimensions (format mix, hook diversity, messaging angles, visual themes, production mix and audience personas), with fixes for the three weakest. No account needed, and Knowlify says submitted ads aren't stored.
Where it falls short. Eight images is a small sample, and you have to collect the ads yourself. On the plus side, that means it works on ads you haven't launched yet.
Knowlify also has a separate free tool called Roast My Ad, not to be confused with AdAmigo's.
7. Meta's opportunity score (in Ads Manager)
Meta's own score lives inside Ads Manager. Meta's developer documentation describes it as a range from 0 to 100 that "reflects how optimized your ad account is", with a higher score indicating a greater likelihood of better performance over time. It comes with recommendations you can apply. In one of Meta's case studies, Omaze followed an opportunity score recommendation to add more partnership ads, and reported a 54% lift in first-time buyers in a conversion lift study.
Where it falls short. It measures how closely your setup follows Meta's recommendations. It doesn't diagnose a specific creative, and a high score doesn't guarantee results.
Which free analyzer should you use?
"My ad is live and it isn't selling"
Start with a tool that reads your results: SellTheClick's analyzer. If it says the problem is before the click, run the creative through Roast My Ad or Adverdly for ideas on the hook. If it's after the click, look at the page, not the ad. Our guide is it your ad or your landing page? walks through it.
"I'm about to launch a new batch"
Check the batch for near-duplicates with the similarity checker, then score individual drafts with Roast My Ad, Adverdly or, for video, Preflight Plus.
"Something feels off about the whole account"
Run Triple Whale's audit on your URL and on a competitor's. If you want to test ads before they're live, use Knowlify's audit with the drafts.
"My account setup might be the problem"
Look at Meta's opportunity score and its recommendations. Then apply them one at a time, so you can see which ones actually helped.
What about free agency audits?
Plenty of agencies and creative studios offer a free audit of one ad, usually returned within a day or two by a person rather than software. They can be genuinely useful, because a human can spot things a model misses. Treat them as what they are: a sales conversation that starts with free advice. If you want an answer in a minute without a call, the tools above are faster.
FAQ
Is there a free Facebook ad analyzer with no signup?
Yes. SellTheClick's analyzer and similarity checker, Triple Whale's Creative Diversity Audit, AdAmigo's Roast My Ad, Adverdly (2 free analyses) and Knowlify's Ad Creative Audit all work without an account. Alison.ai's Preflight Plus needs no card or ad account.
How can I check why my Facebook ad isn't converting?
Compare its click-through rate, cost per thousand impressions and conversion rate with benchmarks. A low CTR points to the hook, a normal CTR with few sales points to the landing page or offer. SellTheClick's free analyzer does this from your Ads Manager numbers.
What is a creative diversity score?
A score of how varied your ads are across dimensions like themes, formats, hooks and personas. Triple Whale and Knowlify both score six dimensions out of 10 and average them.
Is Meta's opportunity score worth following?
It's worth reading. Meta describes it as a 0–100 measure of how optimized your account is, with recommendations attached. Apply recommendations one at a time so you can see what changed results.
Do free ad analyzers need access to my ad account?
None of the third-party tools on this list need it. They work from a URL, uploaded images, pasted copy or pasted numbers. Meta's opportunity score is inside your own Ads Manager.
Can a free tool predict if my ad will work?
No tool can promise that. Pre-launch scorers catch common problems and near-duplicates. Only real spend shows what sells.
