MythForge (officially Game Masters MythForge) is a D&D companion app for Game Masters. It bundles the tools a GM reaches for mid-session into one fast app that works offline at the table: an NPC generator, a monster compendium, an initiative and encounter tracker, a dice roller, and campaign notes with hidden secrets.

How do I generate an NPC for D&D 5e on the fly?

Open the Compendium’s NPCs shelf and tap the wand. MythForge forges a complete 5e-ready NPC in one tap: name, race, occupation, ability scores, an attack, and a roleplaying quirk. Pin an occupation like innkeeper or guard, reroll until it fits, then save it or drop it straight into an encounter.

Does MythForge work offline at the table?

Yes. The bestiary, NPC generator, encounter tracker, dice roller, and notes are all local-first and work with no connection, game shops and basements included. Only the Vault, publishing, and cloud backups need the internet.

How does the initiative tracker handle mobs of monsters?

Add creatures in groups (say, three goblins named as one mob) and MythForge can roll one d20 per group or roll everyone individually. Turn order stays sorted, hit points adjust with one-tap steppers, and conditions and charges live on each combatant.

Can I filter the compendium by type, size, or challenge rating?

Yes. Beasts filter by type, size, challenge rating, favorites, and source; NPCs filter by race and occupation; spells filter by level, school, and class; items filter by category and rarity. Tap a facet button to open its filter sheet, pick as many options as you need, and the shelf narrows instantly.

How much does MythForge cost?

MythForge is a one-time $9.99 on the App Store: no subscriptions, no in-app purchases. It’s in development now; join the waitlist to be first in line when it launches on iOS.

Mythcode is MythForge’s portable stat-block format: plain YAML any text editor can read. Any monster, NPC, item, or spell can be shared as Mythcode text. Paste it to a friend, post it in your group chat, or publish it to the Vault, and it imports back as a fully playable entry on the right shelf.

How do I import a monster, NPC, item, or spell into MythForge?

Open any Compendium shelf (Beasts, NPCs, Spells, or Items) and tap the Import icon in the header, then paste the Mythcode text and tap Import. MythForge confirms what it added and lands you on the right shelf; paste the wrong kind of block and you get a plain-English error telling you what it expected instead of what it got.

Can I share homebrew monsters with other Game Masters?

Yes. With a free MythForge account you can publish your creatures, NPCs, items, and spells to the Vault and pull other Game Masters’ published work into your own library with one tap.

Does MythForge support games besides D&D 5e?

MythForge is built 5e-first: the SRD bestiary, challenge ratings, and the NPC generator target D&D fifth edition. The dice roller, campaign notes, and encounter tracker are system-friendly enough to serve most tabletop RPGs a GM runs.

Is MythForge on Android?

iOS ships first. Android is on the roadmap. Join the waitlist and you’ll hear the moment it lands.

The Vault is MythForge’s shared library: monsters, NPCs, items, and spells published by other Game Masters, free to browse and pull into your own game. Browsing it is free and needs no account at all. A free MythForge account is what lets you pull that work into your library, upvote it, publish your own, and back up everything you have made (creatures, items, spells, campaigns, party, and notes) so you can restore it on a new device.

MythForge brings a complete D&D 5e game master’s toolkit to iOS — offline, and for a one-time price

ONTARIO, Canada — July 26, 2026

MythForge, a game master’s toolkit for Dungeons & Dragons 5th Edition, is coming to iPhone and iPad. It runs entirely on the device, costs a one-time $9.99 with no subscription and no in-app purchases, and is built around a simple premise: the tools a GM reaches for mid-session should work whether or not the venue has Wi-Fi.

Most tabletop apps assume a connection and a recurring bill. Game shops, basements, and kitchen tables routinely offer neither. Every core feature in MythForge — the bestiary, the generator, the tracker, the dice, the notes — works with the network off.

What it does

Generates a complete 5e NPC stat block in one tap — name, ancestry, occupation, ability scores, and derived numbers — for the blacksmith you invented mid-sentence.
Tracks initiative and hit points for a whole encounter, including mobs, without paper.
Draws battle maps with fog of war, and lets players follow along in a browser by entering a code. No app install and no account on their side.
Ships the SRD bestiary offline, searchable and filterable by challenge rating.
Keeps campaign notes with tap-to-reveal secrets, so a GM can open notes at the table without spoiling what is behind them.
Rolls anything, with the arithmetic shown rather than hidden.
Includes a ready-to-run one-shot, so the app is playable the evening it is installed.

A shared library that does not hold your work hostage

MythForge’s Vault is a shared library of monsters, NPCs, items, and spells published by other game masters. Browsing it is free and requires no account at all; an account is what lets a GM pull that work into their own library, upvote it, publish their own, and back up everything they have made.

Everything in the Vault travels as Mythcode — plain YAML any text editor can read. A creature that casts a homebrew spell or swings a homebrew sword brings them along, so what one GM pulls is what the author actually ran at their table. Nothing a GM makes is trapped in the app: it can be pasted into a group chat as readily as published.

Pricing

A one-time $9.99 on the App Store. No subscription, no in-app purchases, and no paid tier of features held back. A free account — needed only for publishing, pulling, and cloud backup — costs nothing.

I kept buying tools that stopped working the moment the game shop’s Wi-Fi went down, or that wanted a monthly fee to keep showing me monsters I already owned. I wanted the opposite: something that lives on the device, that I pay for once, and that hands my own work back to me in a format I can read.
Jeff Caldwell, MythForge
