LiveCodes provides a feature-rich, open-source, client-side code playground supporting over 90 languages and frameworks. It targets developers seeking an immediate, zero-configuration environment for coding, testing, and sharing, eliminating the need for server setup, build steps, or subscriptions. Its core benefit is a "just works" philosophy, enabling instant usability and easy embedding into web pages while prioritizing user privacy.

How It Works

The project operates entirely client-side within the browser, negating the requirement for server infrastructure, databases, or complex build processes. This approach ensures rapid deployment and enhanced privacy. LiveCodes supports importing external resources and modules directly from sources like npm, deno.land/x, jsr, and GitHub, facilitating integration with existing ecosystems. Its design prioritizes a developer-friendly, build-free environment.

Quick Start & Requirements

• Standalone: Access directly via livecodes.io.
• Embedded: Integrate using a provided HTML snippet into web pages.
• Self-hosted: Download releases and deploy on a static file server; a guide is available for GitHub Pages deployment.
• Prerequisites: No specific software prerequisites are listed for core functionality. A GitHub account is necessary only for features leveraging GitHub integration.
• Documentation: Comprehensive docs are available at https://livecodes.io/docs/.
