Create immersive 3D environments using HTML and an entity-component system for platforms such as Quest, Rift, WMR, SteamVR, mobile, and desktop. A-Frame allows developers to build from a basic HTML file without any installation prerequisites, making it highly accessible. A fantastic way to explore A-Frame is by remixing the starter project available on Glitch, a free online code editor that offers instant hosting and deployment. Serving as a web framework dedicated to crafting virtual reality experiences, A-Frame leverages HTML for ease of entry. However, it is more than merely a 3D scene graph or markup language; its foundation lies in a robust entity-component framework that offers a declarative, extensible, and composable architecture built on three.js. Initially developed within Mozilla, A-Frame is now overseen by its co-creators at Supermedium, created with the intent to simplify the VR content development process while maintaining its power. As an independent open-source initiative, A-Frame has flourished into one of the most significant communities in the virtual reality space, fostering collaboration and innovation among developers. This vibrant community continuously contributes to the growth and enhancement of A-Frame, ensuring it remains relevant and user-friendly in the rapidly evolving VR landscape.
