Dulst is a platform for creating, hosting, and playing custom digital card games. It aims to make game development accessible to card game fans, enabling people to turn ideas for new cards and abilities into playable experiences without programming skills. Visual editors help creators build boards, card effects, rules, and game modes, while browser-based HTML5 play, multiplayer networking, and free matchmaking are provided by the platform.

Dulst also includes community tools such as forums, chat, a wiki, achievements, player levels, markets, card sets, and daily quests. Visitors can browse games made with Dulst, including community-created titles and a sample template, or start a new game for free. The Free plan offers unlimited cards and players, automatic single-player AI, card buying and crafting, custom rules, and community features.

Paid Pro and Enterprise plans add capabilities such as dedicated servers, cheat protection, testing tools, access controls, analytics, scalability, and support services. Dulst serves both individual creators and teams seeking tools to build and grow online card-game communities
