localgpt.world is where worlds made with LocalGPT can be visited by anyone. Natural language, a screenplay, Markdown notes and music tracks become places you can walk through — built with the coding agent you already use, shared here.
Each of these was made with one of the LocalGPT apps. Click one to step in; the card tells you which app built it.
Most world-generation platforms keep their worlds inside their own servers and walled gardens. LocalGPT takes the opposite stance: a world is a package on your disk, built by whichever coding agent you use, and it opens anywhere the format does.
Whether it was born from a prompt, a Markdown document, a song or a screenplay, every world here is written in one format: the Open World Format, an open standard LocalGPT doesn't own. The apps save a world as a .world package — a folder holding the world, the log of every edit that built it, and its assets by content hash — so the one viewer on localgpt.world plays them all, and any other reader of the format opens them too.
Your notes, your music library and your worlds are files on your disk, in a format anyone can read. LocalGPT itself sends nothing anywhere; your agent's traffic is its own.
High-performance native ECS rendering pipeline with ultra-fast startup and smooth frame rates.
A document, a song or a package opens as a world in the same window, and your own agent builds in it from a terminal beside it. No model inside, no key.
Open World Format packages: a JSON Schema, conformance worlds, and readers for JavaScript, Python, Rust, Swift and Kotlin. Meshes stay glTF.
# 1. Install LocalGPT Gen, the world builder your own agent drives over MCP
cargo install localgpt-gen
# 2. Or previs a screenplay with nothing installed: drop it on https://localgpt.md
# 3. Or run the desktop app from source: a document, a song or a package as a world
