Checks if you own a game on Steam on various websites
Checks if you already have a game in Steam, Epic, GOG library, itch.io
Works on many websites. https://alexa.weezeewig.com/SteamOwned/SupportedWebsites.html
This extension only looks at your list of games and wishlists. This information is kept on your computer and not sent anywhere.
Go to one of the supported websites.
Click on the "library" icon on the top right of the browser.
Tell me if you want any other sites added.
Warning: double check on steam first.
It will be incorrect if the game name is different than the same game on steam. ie. "Train simulator" on Steam is "Train simulator 2016" on humblebundle. "ABZÛ" on Steam is ABZU on humblebundle. etc...
It won't work if people put things in <code> blocks because we can't insert any links/images into those blocks.
