Why teams pick AdLibrarySpy
- It costs nothing: no card, no trial clock, no credits that run out mid-research.
- Store intelligence built in: SimilarWeb-measured traffic, products, apps and pixels next to the ads.
- No lookup quotas, no cap on tracked brands, and unlimited free teammates.
- A free MCP server, so Claude and other AI assistants can search shops and ads for you — none of the paid tools offer that free.
