Instead of reading the fine print on eight different seller pages, you snap a photo of your item. SellWhere identifies it, scans completed sales to estimate a realistic price range, and compares the major reselling platforms side by side — eBay, Vinted, Etsy, OfferUp, Mercari, Poshmark, Facebook Marketplace, and Depop. You see the real fees, the net profit you'd keep, and the honest pros and cons of each, so you can pick the platform that fits your item instead of defaulting to the one you always use.

SellWhere is built and maintained by a small independent team of resellers and software makers who got tired of doing this arithmetic by hand. Nobody here works for a marketplace, and no marketplace has any say in which platform the tool recommends — the ranking is arithmetic, based on net proceeds after fees and shipping.

The written guides are produced in-house by the same team. Our method, review cadence, and corrections policy are published in full on the editorial standards page.

Every commission rate, flat fee, and payment-processing charge comes from the marketplace's own published seller documentation, not from secondhand blog posts. Rates are reviewed monthly and whenever a platform announces a change, and each guide shows the month it was last reviewed. Where a platform's rate depends on category or a promotion, the tool and the article say so rather than quoting a single headline percentage.

SellWhere is free and supported by advertising. Ads are kept out of the comparison form and away from every button, so they can never be mistaken for part of the tool or clicked by accident. Advertising does not affect rankings, recommendations, or which platforms we cover. We don't sell user data, and there is no paid tier that changes the results.

Found a fee that's out of date, or have an idea that would make the comparisons more useful? Send it through the contact form — we read every message, and a verified correction updates both the calculator and the guides.
