About 7 months ago, I decided to start working on a 5e roleplaying chat with my local AI, using some open source apps others had made at the time. I quickly found that nothing really had all the features I wanted: solo and multiplayer campaigns, an AI that doesn't get lost, sidetracked, or stuck in loops, a workshop to create your own world content, and the ability to run it all on your own machine with a 16GB GPU, or with pretty much any cloud AI provider. And if you don't want to use AI at all and are just looking for a way to host your campaigns remotely, I've also covered that with a human-DM mode. After months of hard work with claude code, codex, some local qwen, and a ton of contributions from a great community, we now have a client app available on Android and PC! Advanced users can still set up and manage their own servers, but less technical users don't have to worry about any of that. The client app can connect to your favorite AI provider or use your own gaming PC, and automatically create a secure tunnel with an invite code for your friends. Your campaign data stays on your own device. I've really tried to think of everything and test all sorts of scenarios along the way. One of my main goals from the beginning was to make it possible to run the full 5e ruleset with an AI Dungeon Master on just a 16GB GPU, without needing expensive hardware or paying for cloud services. We're extremely close to our first "stable" release, with v1.0.0 not far behind! Currently, I've got my own setup running GPT-OSS 20B on my BC250 as the narrator, with another server handling image generation. But plenty of users are just connecting their existing Codex or Claude Code subscriptions instead. The project is open source, and it's been really cool seeing other people contribute and start using something that originally began as a little side project for myself. I know the trailer looks very AI, thats because it is. GitHub: https://github.com/Lebbitheplow/open-dungeon-master Website: https://opendungeonmaster.com   submitted by   /u/lebbi [link]   [comments]
