CrimsonDesert. app is an independent, fan-made companion website for Crimson Desert, the open-world action RPG by Pearl Abyss. It provides free tools and reference material to help players explore the game, plan crafting, and track progress.

Its interactive map features more than 9,300 markers across Pywel, including Abyss Nexuses, quests, resources, and boss locations, with search and category filters. The wiki contains over 1,500 entries on bosses, weapons, armor, quests, skills, mounts, non-player characters, and recipes, supported by stats, farming guides, and cross-links. A crafting calculator lets users choose a recipe and quantity to view required ingredients and their map locations.

The site also offers guides, a weapon tier list, and a quest tracker, with content updates typically delivered daily. Available in eight languages, the responsive web app works on phones, tablets, and computers, and requires no account to browse. Users can sign in with Google to sync progress across devices.
