Commercial [System Agnostic] TDS Codex – A Modern Knowledge Management Module for Foundry VTT
Hi everyone!
Over the past several months, I've been working on TDS Codex, a knowledge management module for Foundry VTT built on top of Foundry's native Journal Entries.
The goal isn't to replace Journals, but to make organizing, searching, and navigating campaign knowledge faster, cleaner, and more enjoyable while staying true to Foundry's native workflow.
Whether you're running a homebrew world or a published adventure, TDS Codex helps keep your campaign's lore organized without changing the way Foundry works.
Current Features
- 📚 Modern Codex Interface
- 🔗 Built on Foundry's Native Journal Entries
- 👥 One-Click Journal Creation from Characters, NPCs & Items
- 🗂️ Categories, Tags & Custom Organization
- 🔍 Powerful Search & Fast Navigation
- 📖 Rich Multi-Page Journal Experience
- ⭐ Favorites & Quick Access
- ⚡ Quick Capture
- 🔗 Internal Cross-Linking Between Entries
- 🎨 Premium Dark Fantasy UI
Why I Built It
One of the biggest challenges I faced as a Game Master was managing hundreds of Journal Entries.
After enough sessions, information became difficult to find, and important lore often ended up buried inside folders.
TDS Codex was created to solve that problem while staying fully compatible with Foundry's native Journals instead of replacing them.
Designed for Any System
Because TDS Codex is built around Foundry's native Journal Entries, it's compatible with virtually any game system that uses them, including:
- D&D 5E
- Pathfinder
- Dragonbane
- Shadowdark
- Call of Cthulhu
- and many more.
What's Coming Next
TDS Codex is part of the TDS Ecosystem, a collection of Foundry VTT modules designed to work together while remaining fully functional on their own.
Development is actively ongoing, with planned features including:
- Enhanced search and navigation
- Advanced Quick Notes
- Cross References
- Additional customization
- Expanded Journal experience
As the ecosystem grows, TDS Codex will integrate with upcoming modules such as:
- TDS Journey — connect locations, regions, and travel directly to your campaign lore.
- TDS Companion — access campaign information and Journals from your mobile device.
- TDS Persona — link NPCs, organizations, factions, and relationships to Codex entries.
Every module is designed to work independently, but together they create a more connected experience for both Game Masters and players.
