MulMarket

Hey everyone 👋

I’m the solo developer behind MulMarket. I’ve been working on it for about a year while actively trading CS2 skins myself.

I built it mainly because I couldn’t find tools that gave accurate fee calculations, proper long-term portfolio tracking, or reliable arbitrage detection across multiple marketplaces.

Most existing solutions either felt too basic or required linking accounts in ways that didn’t feel transparent.

MulMarket runs locally, doesn’t require Steam login, and focuses on giving traders serious analytics rather than just price lookups.

It’s still early stage, so I’m really interested in feedback — especially from people who manage larger inventories or trade across multiple markets.

Would love to hear what features you think are missing in this space.
