简介
NEW: CS2 3D Viewer directly on Steam Community
SteamHelper is a clean inventory, market and trade helper for Steam users.
The Firefox extension adds useful tools directly to Steam Community pages, helping you understand inventory values, compare item prices, review trade offers and inspect CS2 skins in 3D without leaving Steam.
SteamHelper is built for Steam and CS2 users who want more price context when buying, selling or trading items.
▸ Inventory Helper
View estimated Steam inventory values, item price overlays and additional item details directly on inventory and profile pages.
▸ Market Helper
Compare Steam Market prices with external market prices, view additional pricing context and get a clearer overview of listings before making a purchase or sale.
▸ CS2 Skin Helper
View additional CS2 skin information such as float, wear, phase and trade lock status where available.
▸ CS2 3D Viewer
Inspect supported CS2 skins directly on Steam Community pages using the integrated interactive 3D Viewer.
You can view the weapon and skin in 3D without opening a separate website, making it easier to inspect an item before buying, selling or trading.
▸ Trade Helper
SteamHelper improves Steam trade offer pages with item values, side totals and value differences.
While creating or reviewing a trade, you can see the estimated value of both sides before confirming the offer.
▸ Favorites and Price Alerts
Save items to your favorites, watch prices and create one-time price alerts.
SteamHelper can display a browser notification when an alert is triggered.

The extension is designed to operate on relevant Steam Community pages and does not monitor unrelated websites.
SteamHelper does not automatically accept normal trade offers where you give items.
