Create immersive 3D environments using HTML and an entity-component approach for platforms like Quest, Rift, WMR, SteamVR, as well as mobile and desktop devices. A-Frame allows developers to start from a basic HTML file without any installation requirements, making it accessible for newcomers. For those looking to experiment with A-Frame, remixing the starter example available on Glitch, an online code editor that offers instant hosting and deployment at no cost, is an excellent option. As a web framework tailored for crafting virtual reality (VR) experiences, A-Frame leverages HTML, ensuring a straightforward entry point for developers. However, A-Frame goes beyond being a mere 3D scene graph or markup language; its foundation is a robust entity-component framework that delivers a declarative, extensible, and composable architecture for three.js applications. Initially developed within Mozilla, A-Frame is now upheld by its co-creators at Supermedium, designed to facilitate the development of VR content in a user-friendly yet powerful manner. Over time, A-Frame has evolved into one of the most significant open-source VR communities, fostering collaboration and innovation among its users. This community-driven nature further enhances A-Frame's capabilities, as developers continuously contribute to its growth and feature set.
