LiveCodes

What is LiveCodes?

LiveCodes is an open-source, client-side code playground that enables developers to write, test, and share code across 90+ programming languages and frameworks. It provides native support for popular web technologies including React, Vue, Svelte, and Solid, alongside backend languages like Python, Go, Ruby, and PHP, as well as TypeScript. Designed for developers who need a lightweight, self-contained development environment, LiveCodes runs entirely in the browser without requiring server-side compilation or processing. This client-side architecture makes it suitable for quick prototyping, learning, code sharing, and collaboration. The platform can be easily self-hosted on any static file server or CDN, giving users full control over their deployment environment. The tool is built for developers of varying skill levels—from beginners learning new languages to experienced programmers needing a quick sandbox environment. Its feature-rich interface supports common playground workflows while maintaining simplicity in setup and use. As an open-source project available on GitHub, LiveCodes benefits from community contributions and transparency in its development. The combination of broad language support, client-side execution, and self-hosting capabilities distinguishes it from cloud-dependent alternatives, making it particularly valuable for users prioritizing privacy, reliability, and customization options.
