D&D Tools is an independent reference website for Dungeons & Dragons 3.5 edition, created to help players and game masters find and explore game information. Its searchable database brings together material from earlier D&D Tools collections, additional published resources, and content added by the site’s operator. The site is not affiliated with the former team behind dndtools.eu.

Visitors can browse rules and reference material across core books, supplements, adventures, and settings, including Dragonlance, Eberron, Forgotten Realms, and Greyhawk. Its tools cover classes, feats, skills, spells, psionic powers, equipment, magic items, monsters, and non-player characters, alongside topics such as combat, exploration, conditions, deities, traps, and treasure. Search options support detailed filtering, including creature statistics and special abilities. The site also provides character options, prestige classes, and other resources for building and running characters. D&D Tools has a Discord community for communication and makes resources available for users who want to host their own instance. Its collection continues to expand, with updates adding new sections and game data.
