LiveCodes is an open-source, client-side code playground supporting 90+ languages and frameworks, designed for developers, educators, and library authors to prototype, learn, and showcase code instantly in the browser.

🚀 Overview

LiveCodes is a feature-rich code playground that runs entirely in the browser without servers, databases, or setup requirements. It allows users to write, run, and share code in over 90 languages and frameworks, from web technologies like React, Vue, Svelte, and TypeScript to backend languages like Python, Go, Ruby, and PHP.

This project solves the problem of high setup barriers and server dependencies in traditional coding environments, enabling quick prototyping, experimentation, and education with zero configuration. It's built for developers prototyping ideas, educators teaching coding concepts, and library authors embedding interactive demos in documentation and blogs.

The creators built it to provide a free, privacy-focused, embeddable tool that outperforms existing playgrounds in language support and client-side capabilities, filling the gap for a versatile, no-frills developer utility.
