Demo2

Demo2 is a lightweight, open‑source demonstration framework designed to help developers create interactive product demos and tutorials quickly. It was first released in 2023 by the community of the Demo Project Initiative, a group that originally developed the earlier Demo1 tool for teaching programming concepts. The goal of Demo2 is to provide a more modern architecture that supports both web and mobile contexts while remaining easy to integrate with existing code bases.

The core design of Demo2 revolves around modular plug‑ins that allow developers to embed interactive widgets such as live code editors, step‑by‑step walkthroughs, and real‑time preview components. Each plug‑in follows a standardized API, so third‑party developers can create new extensions without needing to modify the core library. Demo2 also incorporates a configuration system based on JSON, enabling rapid toggling of features and layouts. The framework is available under the MIT license, encouraging widespread adoption in educational institutions, developer conferences, and corporate training programs.

Demo2 supports a variety of front‑end frameworks including React, Vue, and vanilla JavaScript, and it can be bundled with tools such as Webpack, Rollup, and Vite. It also includes a small server component written in Node.js that can host demos, provide authentication, and collect usage analytics. While Demo2 is independent of any specific backend technology, it can easily integrate with static site generators and content management systems like Jekyll, Hugo, and WordPress.

Current versions of Demo2 focus on accessibility compliance, supporting WCAG 2.1 standards, and providing support for multiple languages. The project maintains a public roadmap and issues tracker on GitHub, inviting community contributions for new plug‑ins, bug fixes, and documentation enhancements.
