Graby is a search platform for the secondhand designer market, helping buyers and sellers find underpriced, authenticated clothing across established online marketplaces.

Graby covers brands including Maison Margiela, Rick Owens, and Acne Studios, with more brands planned. Example listings include a Rick Owens drawstring hoodie and an Acne Studios puffy gilet. The platform also offers AI-powered analysis, market demand insights, and profit calculations designed to support more informed purchasing and resale decisions. These tools may help users save time researching items, avoid risky buys, source clothing for personal wardrobes, or identify resale opportunities. Graby is aimed at designer fashion enthusiasts as well as secondhand sellers, including people new to sourcing. The company provides plans, a community, and information about its methodology, alongside access to its search service.
