D&D DM Tools
Free in-browser utilities for running Dungeons & Dragons 5e at the table. Every tool is single-page, runs entirely client-side, and needs no account. These tools are part of the Doungim D&D resource library — Doungim is a TTRPG gaming console for D&D and other tabletop role-playing games.

Add characters and monsters, roll initiative, advance turns, track HP and conditions. No login, runs entirely in your browser.

Doungim's main product is a physical gaming console that handles dice, miniatures, and live DM-run sessions. These web tools exist so a DM with just a phone and a tab open can run a full session — track turns, balance encounters, manage spell slots — without an account, an app store install, or a subscription.
Each tool stores state in your browser only. Close the tab and nothing leaves your device.
