About NeoMud
An online multiplayer MUD (multi-user dungeon) inspired by the text games of the 1990s. Players pick from 15 classes and 6 races, fight in tick-based combat, and explore a shared world, with room art and sprites shown above the text log. The developer's GitHub README says the project is built entirely with Claude Code and calls it "100% vibe-coded with AI". It is free to play in the browser at neomud.app, and the MIT-licensed server can also be self-hosted.
How it was built
Partially verifiedThe README says the project is "built entirely with Claude Code", using custom agents and skills in the repository's .claude/ directory. The README also says room background art and music are AI-generated and sound effects come from ElevenLabs; the art tools are not named.
Built iteratively with Claude Code, using custom agents, skills and memory kept in the repository. The README also describes an AI playtester that plays the game and files bugs.

“This project is built entirely with Claude Code, using custom agents and skills in the `.claude/` directory”Verification notes: AI use, launch date, features and the play URL come from the developer's GitHub README. The old URL github.com/terrymaster/neomud now points to roomsmith-games/NeoMud. neomud.app serves a page titled "NeoMud — World Marketplace", but we did not see the game client load.
