Microsoft has launched GitHub Spark, a new tool integrated within its Copilot platform that enables users to build and deploy full-stack applications using natural language prompts. Announced by Microsoft CEO Satya Nadella, GitHub Spark is designed to allow developers and non-coders alike to create apps simply by describing their ideas without needing to write code. The tool offers built-in hosting, AI integrations, and one-click deployment, and is currently available in public preview. Early users have demonstrated its capabilities by creating applications such as converting JSON files to CSV with file upload and download functionality. GitHub Spark supports development on React apps with features like user authentication and persistent storage, aiming to streamline app creation and iteration.
