I made a FREE offline worldbuilding tool for DMs who are tired of subscription apps - it's a single HTML file you just open in your browser
I've been DMing for a while and kept running into the same problem. Either the tool was too basic or I was paying a monthly fee for features I used maybe 20% of. And I never fully trusted cloud tools with years of campaign notes.
So I built something for myself and figured I'd share it.
World Forge is a single .html file. Download it, open it in your browser, done. No account, no subscription, nothing. Everything saves locally and you can export a full backup anytime.
What's in it:
- Characters, factions, locations, religions, creatures, artifacts, conflicts, quests
- A relationship web so you can actually see how your NPCs and factions connect
- Timeline and custom calendar system for tracking your campaign history
- Map section with pins linked to your world entries
- 17 generators for when you need an NPC, town, or plot hook on the fly
- Multiple worlds so you can keep campaigns separate
- Export your full world as Markdown to paste into Notion, Obsidian, or wherever you keep your notes
Built it mainly for long term campaigns where you need to actually remember who knows what and who hates who.
It's on itch. io if anyone wants it. Happy to answer questions.
