ArcanaForge is a free suite of Game Master tools that runs entirely in your browser. No accounts, no ads, no installs required — your data saves locally on your device, and most of it works offline. Built by a DM for an actual weekly table, then polished into something worth sharing.

(The Run tool button above opens a launcher — the full site lives at arcanaforge.com so your saved data always stays in one place.)

THE CODEX — ONE LIBRARY, EVERY TOOL

At the center is The Codex: a searchable, fully editable library of 11,000+ entries — items and gear, magic items, spells, monsters, classes, feats, names, books, shop stock, dungeon rooms, environments, and more. Every generator and sheet on the site pulls from it. Add your homebrew once, and it flows into every tool automatically. Export and import as JSON whenever you like — your data is yours.

GENERATORS

• NPC Generator — names, species, traits, quirks, and appearance drawn from the Codex

• Loot Generator — treasure hoards scaled the way you want

• Shop Generator — a full shop with proprietor, atmosphere, and priced inventory in one click

• Dungeon Generator — rooms, features, and flavor ready to run

• Environment Generator — wilderness and location dressing

• Custom Generators — build your own random tables on the same engine

AT THE TABLE

• Character Sheets & Builder — complete sheets with Codex-powered autofill for spells, gear, and items. Coin tracking does the math for you.

• Initiative Tracker — with a separate player-facing view for a second screen

• Campaign Link — the GM creates a campaign and shares a join code. From there, Group Notes, Group Inventory, and character sheets sync live between everyone at the table.

• Group Inventory — shared containers and party coin with an automatic activity log: who added or removed what, and when. No more "who took the bag of holding?"

• GM tools built in — a GM-only notes section, hidden rolls, and the ability to view every linked character sheet.

THE FINE PRINT (THE GOOD KIND)

• Free. No premium tier, no locked features.

• No accounts. Campaign sync uses anonymous sessions — players just enter a code and a name.

• Private by default. Solo use stores everything in your browser; nothing is uploaded unless you link a campaign.

• Offline-friendly. Install it as an app (PWA) and the tools keep working without a connection.

• Two-edition friendly. 2014 and 2024 content live side by side, clearly tagged.

• All Codex descriptions are original paraphrased summaries — no published rules text is reproduced. ArcanaForge is a reference and organization layer for content you already own.

FEEDBACK WANTED

This started as a personal tool and grew — which means it's shaped by one table's habits. If something is confusing, broken, or missing, I genuinely want to hear it. Leave a comment below and I'll respond.
