HearthCards is an online gallery for browsing and creating custom cards. Its gallery lets visitors explore submitted designs using filters for card type, class, cost, attack, health, rarity, date range, and ordering. Users can also search by card name, making it easier to find particular creations. The site provides a card-entry form where contributors can supply a name, choose a class, enter card attributes, select a rarity, add a set emblem, and include a picture or image URL. These tools support the presentation and discovery of imaginative card designs, including examples associated with themes such as Escape from Violet Hold.

HearthCards also offers community and participation features, including sign-in, news, rules, friendly chat, bug reports and suggestions, and contest ideas. Together, the gallery, creation tools, and community sections make the site a hub for sharing and exploring custom card concepts. The site’s card fields and filters indicate a focus on collectible-style game cards, while its available text does not specify additional products or services.
