A modular, AI-optional TTRPG ecosystem — built for hackers, storytellers, and curious devs.
Fate's Edge is an open, extensible tabletop RPG platform — rules engine, AI GM, multi-client transport layer, voice stack, and VTT surfaces — all designed around one principle.
Every layer should be replaceable, hackable, and fun to build on.
If you love clean architecture, real-time systems, game design, or AI-assisted storytelling, this project is a playground. We're looking for contributors who want to help shape the future of open TTRPG tech.
🌐 What makes Fate's Edge special
One elegant resolution mechanic
Easy to extend, easy to automate.
Deterministic rules engine

Interoperable transport layer
Web, desktop, terminal, Discord, Roll20, Foundry, Python.
Tag-based GM protocol
Safe, test-covered, and easy to extend.
Modular AI GM
Driver-agnostic, state-machine-driven, and fully optional.
Voice pipeline
TTS, ambience, and cloning — all toggleable.
Layered architecture
Every subsystem can be swapped without breaking the rest.
If you enjoy building systems that feel alive, Fate's Edge is your kind of project.
🛠️ Ways you can contribute
