Campaign Forge

Campaign Forge — Complete TTRPG Game Master Suite

17 integrated tools. Zero subscriptions. Fully offline. Your data never leaves your machine.

Campaign Forge is a desktop command center built for Game Masters who run tabletop RPG sessions. Every phase of your campaign — from world-building and session prep to live combat and atmospheric music — lives in one application, with tools that actually talk to each other.

No cloud accounts. No monthly fees. No internet required. Install it, and it works.

Session Prep — Build Your World

Character Rolodex — Your central database for every creature in your campaign. Store party members, NPCs, and monsters with full stat blocks, damage resistances, condition immunities, ability scores, and custom notes. Import thousands of monsters from JSON in seconds. Every character flows automatically into Encounter Builder, Battle Master, and Session Planner.

NPC Forge — Generate rich, unique NPCs with personality traits, backstories, physical descriptions, voice patterns, and plot hooks. Scale from quick tavern strangers to fully realized recurring characters. Export directly to Rolodex or Campaign Codex with one click.

Encounter Builder — Design CR-balanced combat encounters by pulling creatures from your Rolodex. See real-time difficulty ratings as you add monsters. Launch directly into Battle Master when you're ready — all combatants transfer with their stats, HP, conditions, and damage modifiers intact.

Campaign Codex — Rich note-taking with wiki-style entity linking. Write session notes, location descriptions, quest logs, and lore entries. Reference any NPC, character, spell, or music scene with clickable badges. Includes templates, folder organization, smart folders, tags, version history, and markdown export.

Location Builder — Build a hierarchy of regions, cities, dungeons, and rooms. Link NPCs to locations, add descriptions and points of interest, and export locations to Campaign Codex as formatted notes.

Session Planner — Kanban-style session prep board. Drag encounter cards, Codex notes, and NPC references onto your session timeline. Launch encounters directly into Battle Master from the board.

Cartographer — Interactive map viewer with markers, routes, fog of war, and a travel calculator. A battle mode to display combat maps with character tokens. A pop-out player-facing display syncs in real-time. Be able to size, grid, and print table-sized battlemaps with page splicing.

Random Tables — Build custom rollable tables with weighted entries. Encounter tables, loot tables, name generators, weather tables — anything you need. Import and export as JSON or CSV with full roll history tracking.

Live Session — Run the Game

Battle Master — Full combat tracker with initiative, HP, conditions, damage modifiers, and death saves. Manage up to 12 player characters and 20 enemies simultaneously. Mirror mode gives your players a synchronized display on a second screen showing initiative order and health status — without revealing your DM notes.

Music Orchestrator — Scene-based atmospheric audio with multi-lane playback. Build scenes that mix multiple tracks at custom volumes, crossfade between them instantly, and sequence tension from exploration to boss fight. Bind scenes to keys for instant activation. Panic button for immediate silence.

Shop Generator — Context-aware merchant inventory generation. Configure shop type, settlement size, wealth level, culture, and magic saturation to produce thematically appropriate inventories with dynamic pricing, merchant personality, and haggling modifiers.

Loot Generator — CR-based treasure generation using D&D 5e DMG tables. Generate hoards with gold, gems, art objects, and magic items weighted by challenge rating. Draws from 411 built-in items plus any custom packs you create.

Spell Compendium — 319 SRD spells with full details. Filter by class, level, school, concentration, and ritual. Add custom spells or import spell lists from JSON. Bookmark favorites for quick access during play.

Quick Reference — Instant D&D 5e rules lookup. Conditions, actions, skills, and general rules on searchable cards. Includes a 2024 PHB changes comparison tab and custom cards for your house rules.

Item Manager — Create custom items, organize them into packs, and they automatically appear in Loot Generator and Shop Generator.

Classes & Races — D&D class and race reference compendium. Browse class features, subclasses, racial traits, and ability score modifiers. Add homebrew content.

17 Tools. One Connected System.

Campaign Forge isn't 17 separate apps — the tools are integrated. Data flows automatically:

• Creation Flow: NPC Forge → Character Rolodex → Encounter Builder → Battle Master
• Lore Flow: NPC Forge / Location Builder → Campaign Codex → Session Planner
• Commerce Flow: Item Manager → Loot Generator / Shop Generator
• Atmosphere: Music Orchestrator scenes linked from Codex notes and Session Planner

When you create an NPC, it's available in the Rolodex. When you build an encounter, those creatures transfer to Battle Master with all their stats. When you generate loot, it pulls from your custom item packs. Everything connects.
