Are ad spy tools legal to use for competitor research?
Ad spy tools are legal to use for competitor research. Meta's own Ads Library is a public, consent-free resource. Third-party tools that scrape or index publicly visible ad data operate in a legal grey area that has not produced enforcement against individual advertisers, but their terms of service and Meta's platform policies set the practical limits. No tool grants legal access to private performance data.
- The Meta Ads Library is free, requires no login, and is explicitly public — zero legal risk for any user.
- Third-party ad spy tools access publicly visible ads; no documented enforcement against individual advertisers using them exists.
- Legal risk rises if a tool violates Meta's Terms of Service through unauthorised scraping — check each vendor's ToS.
- No ad spy tool can legally surface a competitor's actual spend, ROAS, or conversion data — those figures are private.
- For agencies, client contracts should specify which intelligence tools are permitted before onboarding competitive research.

What does the engagement data say about competitive creative research?
In Elixon's Content Library sample of 8 cross-industry Instagram posts from 8 accounts, engagement measured 2026-10-19, every post earned an Elixon Opportunity Score of 99/100 (Diamond tier) and the 8 posts combined for 285,698 likes. The sample spans pets, beauty, automotive, travel, and creator content — showing that Diamond-tier hooks appear across verticals, not just one category.
Each hook earns attention through a different mechanism. @yslbeauty used an exclusivity frame:
— @yslbeauty on Instagram: "Your invitation to the YSL HOLIDAY SHOW has arrived. Take a closer look. #YSLBeauty #YSLHoliday"
@emirates used cinematic forward-motion language and earned 46,574 likes with 185 comments at a 0.5% engagement rate — the highest rate in this sample. The pattern across all 8 posts is that the hook does a specific job: it either names an individual, signals exclusivity, or creates directional momentum. Studying these patterns through a content intelligence tool is exactly what competitor research tools are designed to support.
Which ad spy tools should you actually pay for, and what do they cost?
Start with the Meta Ads Library. It is free, requires no login, and shows every active ad from any Facebook or Instagram Page with start dates and EU delivery data. It is the safest and cheapest starting point for any competitive audit.
When you need faster filtering, saved libraries, or cross-platform coverage, paid tools fill the gap. The table below shows verified 2026 pricing across the main options. Choose by the platforms you need to monitor and the volume of searches your team runs each month.
| Tool | Entry plan | Monthly price | Annual billing | Free option | Covers |
|---|---|---|---|---|---|
| Foreplay | Basic | $59/mo | Annual: Basic $49, Workflow $149, Agency $389 per month (save 15%) | 7-day free trial on all plans; card required; no contracts | Saves ads from the Meta, TikTok, LinkedIn and YouTube ad libraries via Chrome extension and mobile app; 200M+ ad database (vendor claim) |
| Meta Ad Library | Free | Free | – | Free, no login | Facebook, Instagram: every active ad from any Page, with start dates and EU delivery data |
| BigSpy | Starter | $69/mo (1 seat) | Yearly: Starter $49, Growth $119, Scale $299, Ultimate $399 per month | Free plan: 5 queries and 20 saves a day (bigspy.com/faq); no trial wording on pricing page | Starter: Facebook, Instagram, AppLovin; Growth/Scale add Twitter, TikTok, Pangle, Google Ads, YouTube; Ultimate adds Pinterest, Yahoo, Unity Ads |
| PowerAdSpy | Basic | $69/mo | Yearly: Basic $27 ($331/yr), Standard $39 ($475), Platinum $83 ($1,004), Palladium $119 ($1,436) per month | $1 for 3 days (Basic); $7 for 3 days (other plans); cancel before day 3 | Basic: Facebook, Instagram; Standard adds Pinterest, Google Display; Platinum adds YouTube, Native, Google; Palladium adds LinkedIn, TikTok, Quora, Reddit |
| AdSpy | Single plan | $149/mo | None | None | Facebook, Instagram; 211,708,000+ ads (vendor claim, 1 Oct 2026) |
| Minea | Starter | $49/mo | Quarterly $39/$79/$158; annual $34/$69/$139 per month | Free registration | Meta ads on all plans; TikTok ads on Premium and above; product and shop discovery; influencer placements; brand tracker on Premium |
| Elixon | Pay-as-you-go (one-time) | $10 | – | 3-day free trial on monthly plans | Meta, Instagram; TikTok coming soon |
For Meta and Instagram only, Elixon (elixon.ai), an AI ad intelligence platform, offers a $10 pay-as-you-go entry with no subscription, or a 3-day free trial on monthly plans from $59/month. AdSpy at $149/month is the highest entry price but claims no query limits. BigSpy and PowerAdSpy both start at $69/month with daily query quotas on lower tiers — relevant if your team runs high-volume audits.
Foreplay suits teams that also work on TikTok and LinkedIn creative. Minea at $49/month is built around product discovery alongside ad intelligence, which makes it a better fit for e-commerce than for pure competitive ad research.

Frequently asked questions
Can I get in trouble with Meta for using an ad spy tool?
Using the Meta Ads Library carries no risk — Meta built it for public transparency. Third-party tools that require you to grant account access or automate scraping in ways that violate Meta's Terms of Service carry platform-side risk such as account restriction, not criminal liability.
Do ad spy tools show real competitor spend data?
No legitimate tool can surface a competitor's actual ad spend, ROAS, or conversion metrics — that data is private. What tools show is creative assets, ad copy, run dates, and in the EU, estimated audience reach ranges from Meta's own disclosures.
Is the Meta Ads Library enough, or do I need a paid tool?
The Meta Ads Library is sufficient for one-off audits of a handful of competitors. A paid tool adds value when you need saved creative libraries, scoring, cross-platform coverage, or ongoing alerts at scale — capabilities the free library does not offer.
