Sell on every platform, manage it all in one place
Photograph your cards. KartIO recognises them, prices them from the market and writes every listing, then publishes them on Vinted, eBay, Cardmarket and CardTrader, and keeps them in sync: when a card sells on one, it comes down from the others.

Frequently asked questions
What is KartIO?
A Mac and Windows app for people who sell trading cards and sports cards. It is a channel manager: one inventory listed on several platforms at once (Vinted, eBay, Cardmarket, CardTrader and, in the US, TCGplayer), kept in sync, with prices and listing texts made from a photo of each card.
Which platforms can I sell on?
In the UK, Ireland and the rest of Europe: Vinted, eBay, Cardmarket and CardTrader. In the US: eBay, TCGplayer and CardTrader. Some countries also get their big local marketplace (see Where to sell). For Facebook, Whatnot and Voggt KartIO prepares the texts and photos to post.
How does the sync stop me selling a card twice?
Each card keeps one record per platform. When it sells (the sync brings the sale back, or you mark it sold), KartIO flags its other listings and takes them down in one click: deleted or ended where the platform allows, hidden where it can only hide, and listed for you to remove by hand where KartIO cannot reach.
In which language are my listings written?
Each platform gets the language its buyers search in: local ones such as Vinted in your country’s language, international ones (eBay, Cardmarket, CardTrader, TCGplayer) in English. The card’s own language (English, Japanese, German…) is written into the title.
Where do the prices come from?
In Europe from Cardmarket, in the US from TCGplayer, and for sports cards from what sold on eBay. KartIO keeps them in sync with the latest market prices, converts them to your currency and applies your own rules. Your prices never change unless you press Apply.
Which cards are supported?
Pokémon TCG, One Piece Card Game and Riftbound (recent sets), and sports cards: NBA, WNBA, EuroLeague, NFL and soccer, Panini Prizm, Select, Donruss, Adrenalyn XL and more, PSA/BGS/SGC slabs and sealed boxes.
