Humble Steam Check por Decobus

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:

1. Get a free Steam API key from steampowered.com
2. Enter your API key and 64-bit Steam ID in the extension popup
3. Hit Save & Sync to pull your library
4. 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.
