Diorama
MIT-licensed engine that draws 2.5D game assets from TypeScript code and exports sprite sheets.
Announced on October 23, 2026 by @dioramadev. The GitHub repo was created on October 22. It is an open-source engine for props, scenery, rigged characters, gear, effects, item icons, and HUD, written as TypeScript. Assets are drawn in one shared camera and light and exported as sprite sheets with an atlas JSON. It is built to be driven by coding agents such as Claude Code, and it ships agent skills and guides. It does not use image models. Output is deterministic. It includes a local web viewer. It requires Node.js 20 or newer and Playwright Chromium. The project is very new.
