Checkey is a free browser extension developed by esquiafo that allows users to easily search and display prices of regional keys on various online stores. With its integration with Steam, users can also search for activatable keys on the Steam platform.

One of the key features of Checkey is its ability to show the current price of the selected key. This makes it convenient for users to compare prices across different stores and make informed purchasing decisions.

In addition, Checkey offers an integrated Trustpilot feature, which allows users to view comments and reviews from other users about the store. This can be helpful in assessing the trustworthiness and reputation of the seller before making a purchase.

It's important to note that while Checkey provides prices from different stores, it does not guarantee the authenticity of the products. The absence of a game on the list does not necessarily mean it is unavailable. Users are advised to verify the authenticity and/or reputation of the seller before making a purchase.

Overall, Checkey is a useful tool for gamers and bargain hunters who want to find the best regional key prices on Steam and make informed purchasing decisions.
