BigSpy Alternatives
Most people looking for a BigSpy alternative are actually looking for a platform BigSpy doesn't cover: its own site lists 11 ad channels, and LinkedIn isn't among them. Before switching tools, it's worth checking what's actually missing, and whether the replacement covers it, rather than assuming any ad-spy tool is interchangeable with any other.
What to check before switching away from BigSpy
Three things separate a genuine alternative from a lateral move. First, platform coverage: BigSpy's 11 channels are Facebook, Instagram, AdMob, YouTube, TikTok, X, Pinterest, Yahoo, Unity and Pangle plus AppLovin, so confirm the replacement actually covers the platform you need, since "ad-spy tool" doesn't imply the same channel list.
Second, the kind of context on each ad: BigSpy's filters are built around interest and ecommerce category targeting, not company firmographics like funding stage or size, so a B2B-specific alternative needs to add that layer rather than just matching BigSpy's own filter set. Third, archive depth: confirm whether the alternative keeps ads after a campaign ends, or only shows what's currently running, the same question worth asking of any ad-spy tool.

Who AdPeekly fits, and who it doesn't
AdPeekly fits a B2B marketer whose research question is specifically about LinkedIn: what a competitor is running, since when, and what that implies about their funding stage or company size. It doesn't fit anyone still needing BigSpy's other ten channels, Facebook and TikTok research in particular stay outside AdPeekly's scope entirely, by design.

Questions about BigSpy alternatives
AdPeekly, but only because BigSpy isn't an option here at all: its own platform list names 11 channels, Facebook, Instagram, AdMob, YouTube, TikTok, X, Pinterest, Yahoo, Unity, Pangle and AppLovin, and LinkedIn isn't one of them, confirmed on bigspy.com 28 September 2026. If the research is specifically about LinkedIn B2B advertisers, AdPeekly is built for exactly that: a dedicated archive rather than a broader tool that happens to be missing the platform you need.
BigSpy itself markets a free tier alongside its paid plans, so if the goal is staying on BigSpy's 11-channel platform for less money, check its own pricing page for current terms. If the goal is specifically free LinkedIn ad research, AdPeekly's MCP tier covers 3 searches a day against the full published dataset with no card required, though it's LinkedIn-only rather than BigSpy's ten-platform-plus-LinkedIn-shaped hole.
Yes: AdPeekly does, and it's built around nothing else. 266,919 published LinkedIn ads from 649 curated B2B companies, each one enriched with industry, funding stage, company size and buyer ICP, kept after the campaign ends and searchable across the whole dataset at once. That's the trade for not covering BigSpy's other ten channels: depth on the one platform BigSpy skips entirely.
