Your drops vs case odds

Your observed rates against published weapon-case odds; percentages are approximate. Source: Perfect World odds disclosure (2017). Each tier has its own scale, so compare a bar with its marker, not one tier with another.

Small histories can differ sharply from the published odds. Past pulls do not change the odds of the next case. A tier you have not pulled yet shows an empty bar, with its odds marker at the end.

Each skin gives its collection an equal share of the odds, split across that collection's next-tier skins. Covert skins (5 per trade-up) can turn into a knife or gloves from the same case. Output float is the average input float scaled into each output's range.

Running in three steps.

Sign in once from your phone. After that it keeps the history on its own.

  1. Sign in once

    Press Show QR code and scan it in the Steam mobile app. No password stored, no browser extension.

  2. It reads and remembers

    Inventory and storage units sync from the Game Coordinator into one SQLite file, with hourly value snapshots.

  3. Move, never sell

    Reorganise items between your own containers. It reads and moves. It never lists, trades or sells.

Five views of one ledger.

Questions, answered.

Does it ever sell or trade my items?

No. OpenInventory reads your inventory and moves items between your own containers. It has no listing, pricing-post or trade feature, and it never will.

Where does my Steam login live?

In a session.json file on your own server, written with mode 0600 and deleted when you press Sign out. It is never sent to us, because there is no us to send it to.

Do I have to self-host?

That is the only way it runs. One Docker command starts it on your machine or a box you control. There is no hosted cloud version to sign up for.

What if CS2 is already running?

Steam allows one game session per account. OpenInventory waits politely and connects when you close the game. It never forces the session.

Where do the prices come from?

Seven marketplaces, with Buff163 as the default. Skinport, Steam, CSFloat, CS.MONEY, Youpin898 and LIS-SKINS can be enabled in Settings.
