Matt Dinniman’s official website showcases the books, adaptations, and merchandise connected to the author and the Dungeon Crawler Carl universe. Its central series follows Coast Guard veteran Carl and Princess Donut, his ex-girlfriend’s cat, as they battle to survive a trap-filled, video game–style dungeon after the end of the world. The site also features Dinniman’s other novels, including the sci-fi thriller Operation Bounce House, along with works spanning LitRPG, fantasy, and horror.

Readers can explore the series through audiobooks and Soundbooth Theater’s immersive audio dramas, which add a full cast, original music, extra scenes, and bonus content. Other offerings include a Webtoon adaptation, graphic novels, side stories, and tabletop role-playing and deck-building games. The Dinniverse brings together these different ways to experience the stories and characters.

The website also directs visitors to signed and special-edition books, an official merchandise store, and partner shops selling themed apparel, pins, and chocolate. Fans can find news, event information, a newsletter, and links to Patreon and community channels.
