Comparison
AdPeekly vs. BigSpy
BigSpy is an 11-channel ad-spy tool built for Facebook, Instagram, TikTok, YouTube, Pinterest and consumer ecommerce research. LinkedIn is not one of its channels. AdPeekly is the opposite shape: a single-platform archive built for LinkedIn B2B advertising, with the funding stage, company size and duration data a consumer ad-spy tool was never built to track.

Who each tool is actually for
BigSpy is built for performance marketers and dropshippers hunting winning creative across consumer platforms, with dedicated research tools for TikTok Shop and ecommerce ad categories layered on top of its 11-channel library. If the research question is "what's working on TikTok right now for a DTC brand," BigSpy is the right shape of tool for it.
AdPeekly answers a different question by design. Nowhere in BigSpy's own channel list is LinkedIn, so a B2B marketer benchmarking LinkedIn campaigns is not choosing between the two tools, they're choosing AdPeekly by default. What AdPeekly adds beyond just being on the right platform is the context a B2B evaluator filters by: funding stage, company size, buyer ICP, and how long a competitor kept paying for the creative that worked, none of which a consumer-facing interest-targeting tool is built to track.

Questions about AdPeekly and BigSpy
No. BigSpy's own platform list, published on its site, names 11 ad channels: Facebook, Instagram, AdMob, YouTube, TikTok, X, Pinterest, Yahoo, Unity, Pangle and AppLovin. LinkedIn is not among them, and nothing in BigSpy's navigation, features or research tools references it. That's not a small gap for a B2B marketer specifically researching LinkedIn campaigns, it's the whole category the tool doesn't touch. AdPeekly covers exactly the platform BigSpy skips: LinkedIn only, with every ad enriched with the advertiser's industry, funding stage, company size and buyer ICP, which is the context a B2B research question actually needs.
BigSpy markets itself as a free ad-spy tool and offers a free tier alongside paid plans, check its own pricing page for current tier details and limits, since those change independently of this page. AdPeekly's free tier works differently: it's MCP access rather than a web dashboard, a set number of searches a day against the full LinkedIn dataset with no card required, meant for querying through an AI assistant like Claude or ChatGPT rather than browsing a UI. Both tools have a real free way in, they're just free for different research habits.
Since BigSpy doesn't cover LinkedIn at all, "alternative" here really means "a different tool for a different platform" rather than a like-for-like swap. AdPeekly is built specifically for that platform: 266,919 published LinkedIn ads from 649 curated B2B companies, each one carrying observed campaign duration, funding stage, company size and buyer ICP, searchable across the whole set at once instead of one advertiser at a time. If TikTok, Facebook or ecommerce creative research is still part of the job, BigSpy's 11 channels remain the tool for that half of the work, the two aren't mutually exclusive.
The difference is scope, not just feature count. BigSpy is a wide, consumer-facing ad-spy tool: 11 channels, ecommerce and TikTok Shop research tools, and filters built around interest and category targeting rather than company firmographics. AdPeekly is narrow on purpose: LinkedIn only, but with the context a B2B evaluator actually filters by, industry, funding stage, company size and how long a competitor's ad kept running after it launched. Choosing between them is really choosing what question you're asking: "what's working across consumer ad platforms" points to BigSpy, "what is this LinkedIn competitor's ad actually saying, and to whom" points to AdPeekly.
