RPG-JS

RPG-JS is an open-source TypeScript framework that enables developers to build both single-player RPGs and massively multiplayer online RPGs (MMORPGs) using the same codebase, targeting the browser. It is designed for web developers and game creators who want to rapidly prototype or launch multiplayer role-playing games without managing separate client and server logic. Its key innovation lies in seamlessly bridging single-player and multiplayer modes, making it an interesting tool for indie developers seeking to scale their projects from solo experiences to persistent online worlds.
