CSTRADEUP Extension

Chrome extension for cstradeup.net — sync your Steam CS2 inventory and trade-up history to track your portfolio and analyze trade-ups.

Features

• Inventory sync — Automatically picks up your CS2 inventory from Steam and sends it to cstradeup.net so you can simulate tradeups with private skins.
• History crawl — Walks through your full Steam inventory history (trade-ups, storage unit moves, etc.) to provide a complete view of portfolio value over time and display statistics on past trade-ups.

How it works

The extension runs offscreen scripts to steamcommunity.com on your behalf to fetch inventory and history data. Data is relayed to your cstradeup.net account and nowhere else.
