Best Spy Tools for Affiliate Marketing in 2026: 8 Tools Compared

AdSpy is the specialist choice for affiliates who spend mainly on Facebook and Instagram. Its large database and detailed filters let buyers search by text, page, affiliate network, landing page and engagement, then view the landing page behind an ad. That depth helps media buyers spot which offers and angles have run for a long time, which is often a sign of a working campaign.

The catch is price and scope. There is one plan at 149 dollars per month, with no cheaper tier and no free trial, and coverage is limited to Meta platforms. A solo affiliate on a tight budget may find that hard to justify, and a native or TikTok buyer will need another tool. For Meta focused affiliates, though, AdSpy depth is hard to match, and it rewards buyers who actually study filters rather than browsing trending ads.

AdPlexity sells separate intelligence tools for desktop, mobile, native, push, ecommerce and other traffic types, which suits professional affiliates who work in one channel deeply. Filters for device, carrier, country and traffic source help buyers find campaigns that match their setup, and landing page views show the full funnel behind an ad. That detail matters for native and push, where the landing page often matters more than the ad itself.

The drawback is cost structure. Each traffic tool is priced separately, so a buyer who wants several channels will pay for several subscriptions. There is also no free plan, so a demo or short paid test is the way to check fit. AdPlexity is best for affiliates who already know their traffic type and want professional depth in that channel.

BigSpy covers Facebook, Instagram, TikTok, YouTube, Pinterest and other platforms in one place, which makes it a useful starting point for affiliates who test several channels. The basic plan starts around 9 dollars per month, and a free plan lets new buyers try searches before paying. For creative inspiration across platforms, that breadth at a low price is appealing.

The honest catch is that the basic plan has tight daily search and data limits, and most serious users move to the Pro plan at around 99 dollars per month. Data freshness can also vary by platform, so check dates before acting on an old ad. BigSpy fits beginners and budget buyers who want a broad view, while professional buyers may pair it with a specialist tool for their main channel.

Anstrex is a strong choice for native, push and pop affiliates, with tools that track advertisers, show landing pages and help buyers follow campaigns over time. Its landing page features are useful for studying funnel structure, headlines and offer flow, which are often more instructive than the ad alone. A short trial lets buyers test whether its coverage matches their networks and geos.

The limitation is learning curve and pricing clarity, since Anstrex sells several products at different rates. New buyers should start with one product, learn its filters, and check coverage for their specific geos before adding more. Used lawfully, with original creative and landing pages, Anstrex helps affiliates learn from public campaigns without copying them.

PowerAdSpy covers several major channels in one subscription, including Facebook, Instagram, YouTube, Google Display and native ads. That mix suits agencies and affiliates who run campaigns across social and search, and who want one tool for creative research. Engagement filters and landing page previews help buyers separate ads that ran briefly from ads that sustained spend.

The catch is uneven depth. Coverage and freshness are stronger on some platforms than others, so check your main channel before buying. Higher plans also open up more searches and data, which means the starting price is not always the full cost for heavy users. PowerAdSpy is a good middle ground for multi-channel buyers who want breadth without buying several specialist tools.

SpyPush focuses on push notification campaigns, a channel where general ad tools often have thin coverage. Its database, landing page previews and filters for network and geo help push affiliates find working angles and offers in their target countries. For a push specialist, that focus is more useful than a broad tool with only a few push ads.

The drawback is narrow scope and pricing clarity. Push is the whole product, so social or native buyers will need another tool, and pricing should be confirmed on the vendor site before budgeting. SpyPush fits affiliates who already run push traffic and want a dedicated research tool for that channel, rather than a generalist starting point.

Meta Ads Library is the free, official place to see ads currently running on Facebook and Instagram. It is useful for quick checks on a competitor page, a brand claim or an offer, and it requires no subscription. For a new affiliate, it is the right first step before paying for a spy tool, since it shows what is live right now.

The limitation is depth. The Library does not offer the historical data, engagement filters or landing page analysis that paid tools provide, and searches are more basic. It also only covers Meta platforms. Use it for free, current research and compliance checks, then add a paid tool when you need history, filters and funnel views across more channels.

Semrush is not a pure ad spy tool, but its Advertising Research features make it useful for affiliates who run search and display campaigns. Buyers can see competitor ad copy, keywords, landing pages and estimated traffic, alongside SEO and PPC data in the same platform. That combination helps affiliates who want to understand both paid and organic competition for an offer.

The catch is social coverage. Semrush does not replace AdSpy or BigSpy for deep Facebook, TikTok or push research, and its best value comes when the team already uses it for SEO. For search focused affiliates, though, Semrush adds a useful layer, since it links ad research to keyword intent and landing page performance in one report.
