Where campaigns live
Between sessions, campaigns live in notes apps and fading memory. DMM gives them a proper home. One connected record for sessions, encounters, characters, and world events, built natively for 5.5e.
Character sheets track builds. DMM tracks campaigns. Every session gets logged, every encounter recorded, and every NPC, location, and world event connects to the same living record. The DM manages it, players connect to it, and nothing gets lost between sessions.
No more juggling notebooks, spreadsheets, and twelve different browser tabs.
Organize your world across multiple campaigns. Manage players, session context, and campaign-wide data from a single dashboard that keeps everything connected.
A full 5.5e character creation wizard covering race, class, subclass, ability scores, background, and equipment, guided step by step.
Run encounters without missing a beat. Initiative order, hit point tracking, conditions, and participant groups, all updating in real-time across every connected device at your table.
Build your world location by location. Upload battle maps and overworld images, write rich location notes, and push maps to a second screen with basic VTT display support.
Browse the full SRD creature list for 5.5e encounters. Create homebrew monsters and NPCs, link them to locations, and track them as persistent characters across your campaign.
Your players get a dedicated mobile app. Character sheets, spell management, inventory, and live map display from the DM, so they're always in the action on their own device.
The best sessions start with good prep. DMM gives you the tools to build your world in detail, create characters from scratch, and have everything you need within reach before the first dice roll.
When the session starts, DMM keeps pace. Combat runs through a live tracker, maps display on demand, and players follow along on their own devices without interrupting the flow at your table.
The campaign doesn't end when the session does. DMM keeps a running record of everything that happened, so the next session starts with full context and nothing falls through the cracks.
The visual tabletop is up to you. Everything else is DMM.
Sessions end. The campaign keeps going. DMM maintains a running record of encounters, discoveries, NPC relationships, and world events, so nothing gets lost between sessions.
Running in-person with minis? Playing online through Foundry or Roll20? DMM sits alongside whatever setup your table uses. It's not a VTT and it's not trying to be one.
The DM builds the world. Players live in it. Character sheets, inventory, and session history all connect to the same campaign, so everyone is working from the same record.
Built around the 2024 Player's Handbook, not retrofitted from older editions. New rules, new classes, new mechanics, all natively supported from the ground up.
Initiative order, hit point tracking, and conditions, all in one view. Whether you're running theatre of the mind or pushing minis on a grid, the mechanical layer is handled.
Create custom monsters, items, and creatures that live alongside the official SRD library. Your homebrew content is fully integrated into every workflow, not bolted on as an afterthought.
When your DM runs their campaign through DMM, you get a companion app with everything you need at the table. No paper sheets, no shared PDFs, no "hang on, let me find my spell list."
Your full character sheet lives in the app. Stats, proficiencies, saving throws, and features, all in one place and always current.
Track spell slots, prepared spells, and concentration without a pencil. Your resources update as you use them through the session.
Everything your character is carrying, right there. Add and remove items without hunting for the eraser.
Roll from your phone or tablet, or enter results manually if you prefer real dice. Either way, the maths is handled.
Your character lives inside the campaign record, not as a standalone document. The DM can reference your sheet, and your character grows alongside the world.
