Methodology
How these prices are read
Every vendor figure on this site comes from the vendor’s own page or, where marked, from its app on our account, with the date it was read. Our own tests are labelled as ours. Where a vendor publishes no figure, the page says “not published”.
Where the figures come from
Each vendor public pages are read directly: pricing pages where they exist, home pages where they do not. A figure is recorded only when the vendor states it itself. The date of reading is printed beside every table, so a reader can check whether the number has moved since.
Roughly half of these vendors serve a pricing page as plain HTML. The rest return an access error, a 404, or an empty shell that only fills once scripts run — and in two cases the price is not on a pricing page at all. Where that happened, the page actually read is named below, so the check can be repeated rather than taken on trust.
The page read for each tool
Eleven tools, one page and one reading date each.
| Tool | Page read | How | Date |
|---|---|---|---|
| spytrend.com/pricing | plain HTML, read with a normal request | 13 Nov 2026 | |
| adspy.com | single plan stated on the home page; no separate pricing page | 13 Nov 2026 | |
| bigspy.com | public pricing page serves an empty shell; tiers read on the home page, channels per plan inside the app | 13 Nov 2026 | |
| trendtrack.io/pricing | prices are animated digit reels; the values sit in the card's data attribute. The number is the same from Germany and the US, but the currency symbol swaps: € in Europe, $ in the US | 13 Nov 2026 | |
| minea.com/pricing | plain HTML, read with a normal request | 13 Nov 2026 | |
| pipiads.com/pricing | the pricing page is empty without JavaScript, so its five tiers are read in a browser and checked by hand | 13 Nov 2026 | |
| poweradspy.com/pricing | plain HTML, read with a normal request | 13 Nov 2026 | |
| adplexity.com/pricing | plain HTML; yearly toggle is the default view (yearly prices with monthly struck through); Black Friday banner on 31.10 (up to 50% off yearly, until 30 Nov) — temporary, not in the table | 13 Nov 2026 | |
| anstrex.com | prices on the home product cards and in the #pricing block of /product/native and /product/push; /pricing returns 404 | 13 Nov 2026 | |
| facebook.com/ads/library | Meta's own tool, no paid tier exists | 13 Nov 2026 | |
| app.dropispy.com | public pricing page did not load; plans read inside the app on our Premium account | Oct 14, 2026 |
What this site does not do
No composite score
A single number out of ten hides which axis a tool leads on. Each table compares one measurable thing at a time.
No paid placement
No vendor has paid for a position, a mention or a link on this site, and none has been offered one.
Links earn this desk nothing
Every link to a vendor points at that vendor own page with no referral code, so the ordering cannot be bought and there is no commission on a sale.
No ranking where the evidence is missing
Five of these ten publish no database size at all: PiPiADS, PowerAdSpy, AdPlexity, Anstrex and the Meta Ad Library. Their coverage is not compared on numbers anywhere, and no estimate is substituted.
Our own tests
Some figures are ours, not the vendor’s, and every page says so where it uses them. The main one is a freshness check: on November 4, 2026 we ran two fixed product searches in the tools we hold accounts on, sorted newest first, and wrote down the newest launch date each one printed. It shows how fresh a tool looked that day, not what it misses.
A second, narrower check measured delay — days from an ad’s launch or post date to the day a tool first saw it — on ads each tool already held for two advertisers. That sample comes from the tool itself, so it shows speed on what a tool has, not what it misses, and we never present it as coverage. Smaller checks, such as one search on BigSpy’s free plan against the Meta Ad Library, are described next to the screenshot that records them.
Corrections
If a figure here is wrong, the fix is the same as for any figure on this site: the vendor page is read again and the number is updated with a new date. Prices in this category move — a standing discount becomes the real price, a free plan turns into a trial — so the reading date next to a number matters as much as the number.
Prices were last re-read on 13 November 2026, and are re-read once a quarter.
