The D&D companion app built for Game Masters
Forge NPCs in a heartbeat, run encounters without paper, roll anything, and keep your campaign’s secrets, at the table or between sessions, online or off.
Coming first to iOS: a one-time $9.99. Join the waitlist and be first at the table.
In the driver’s seat
The rules, normalized. The call, yours.
MythForge does the bookkeeping so you don’t have to. Ability scores, proficiency, hit points, spell slots, class resources, and save DCs are computed and normalized to 5e. Build an NPC as a level-12 half-elf bard and the numbers come out right, every time.
But the mechanics are a starting point, not a straitjacket. MythForge tracks; you rule. Every result is a suggestion you can override. Bend a stat, waive a cooldown, or improvise a ruling, and the app keeps up instead of fighting you. You’re the Game Master. The tools serve the table.
The Forge
Generate NPCs faster than your players can derail the plot
The party just befriended the blacksmith you invented mid-sentence? One tap forges a complete D&D 5e stat block: name, race, occupation, abilities, an attack, a quirk worth roleplaying. Pin an occupation, reroll until it fits the scene, and save straight to your compendium.
The Bestiary
Every SRD monster in your pocket, and every one of yours
Search full 5.1 & 5.2 SRD stat blocks, fully offline: actions, legendary actions, reactions, saves, and resistances included, not just the ability scores. Facet buttons narrow beasts by type, size, challenge rating, favorites, or source, and NPCs by race or occupation, on their own shelf one search away. Build homebrew creatures in the editor, scan paper stat blocks with the camera, or import any monster, NPC, item, or spell shared as Mythcode straight onto its shelf.
At the Table
Initiative, hit points, and conditions without the paperwork
An encounter tracker that thinks like a Game Master: group initiative for mobs, one-tap damage and healing, conditions, charge tracking, and loot with investigation DCs. Named counters (a ritual clock, an alarm, a reinforcement pool) tick automatically each round and warn you with a banner the moment they matter. Stage reinforcements to arrive on a later round and deploy them with one tap and a shared initiative roll the moment the arrival banner goes up. When the dust settles, the Spoils screen splits the XP by who earned it.
The War Table
Lay the fight out on the map
Drop tokens on a five-foot grid, sketch walls, trees, rocks, and treasure as you build the room, and move pieces without losing the turn order underneath. Aim a spell before you cast it: MythForge lights up every square inside its range so you commit with your eyes open. When the table needs to see it, cast the board to your players’ phones. They open a link in any browser, no app to install, and get the very same map, icon for icon, minus whatever you’ve fogged. Paint fog over the rooms they haven’t found and lift it square by square as they explore: a fogged square isn’t dimmed on their end, it’s never sent there, and neither is the monster standing on it. Point at a square and your marker flares up for everyone; or drop the whole board into chat as an image, in your view or theirs.
The Dice
Roll anything a tabletop can throw at you
Full dice notation (4d6 drop lowest, advantage, disadvantage, modifiers) or tap together a pool in the dice tray, from d4s to d20s, and let MythForge write the notation for you. Quick-roll chips cover the classics, favorites remember the rolls your table makes every session, and natural twenties get the celebration they deserve.
The Journal
Campaign notes that keep your secrets
Write session recaps once: players get the shareable version, you keep the truth. Wrap spoilers in hidden blocks that reveal with a tap and hide again with a long-press. The villain’s name stays yours until the moment it lands.
The Vault
Share your creations with Game Masters everywhere
Publish your monsters, NPCs, items, and spells to the Vault so other Game Masters can find them, then browse theirs by kind, newest or most-upvoted first, with a full preview and an upvote before anything touches your library. Everything travels as Mythcode, and any spells or items a creature depends on ride along with it. Your free account also backs up your whole library (creatures, items, spells, campaigns, party, and notes), so a new device is a restore, not a rebuild.
Questions from the table
Game Master FAQ
What is MythForge?
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.
What is Mythcode?
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. Read the full Mythcode format reference.
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 Vault 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.
What is the Vault?
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. A free Vault account gets you in, and also backs up your whole library (creatures, items, spells, campaigns, party, and notes), so you can restore it on a new device. Everything else in the app works without an account.
