Features & Capabilities

Stop buying games you already own. Humble Steam Check scans every Humble Bundle page and marks games that are already in your Steam library with a green Owned badge. Wishlisted games get a blue badge too.

How it works:

Get a free Steam API key from steampowered.com
Enter your API key and 64-bit Steam ID in the extension popup
Hit Save & Sync to pull your library
Browse Humble Bundle — owned and wishlisted games are marked automatically

Features:

Green badges on games you own, blue on wishlisted
Fuzzy name matching catches renamed editions and minor title differences
Works on bundle pages, store pages, and choice pages
Your data stays local — nothing is sent anywhere except Steam's own API
Syncs your library on demand with one click

Privacy: No data collection. No analytics. No tracking. Your Steam API key and game list never leave your browser.

Is Humble Steam Check Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Humble Steam Check requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Humble Steam Check may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
