People who browse this category may use A-Frame as it is an open-source web framework for building 3D, AR, and VR experiences with HTML.
A-Frame is best known as the open source framework for creating VR and 3D experiences in the browser. It is used to create WebXR projects and scenes.
In most cases a-Frame is not the retail shopping website, so the promo codes are not relevant for it. This is just the open source framework that provides developers with the docs and other materials.
Developers can create browser-based 3D and VR prototypes using free tools without spending a lot of money on proprietary software at the beginning. Later they might need to pay for hosting, assets, devices, or additional coding.
Most of the users can get a-Frame for free since it is the open source framework. However, people should check the license and other third-party components.
It would be reasonable to say that a-Frame can be used by all web developers, educators, artists, researchers and other people interested in VR or 3D web experiences. It would be very convenient for people with HTML and JS skills.
A-Frame can be used in commercial projects with the conditions of the license and other used components. People need to check the requirements carefully.
It does not require the VR headset. Most of the scenes can be viewed in the browser, but for VR or AR experience there might be required some devices.
