The Orange Design System is the French telecom's open-source toolkit spanning Web, Android, iOS, and TV platforms, with over 100 ready-to-use components and 1,700+ icons in Orange's own Solaris visual style.
It's strongest for genuinely cross-platform telecom UI, dedicated SDKs for both Android and iOS ship alongside the web components, and sustainability is documented as a named standard alongside accessibility and security, not treated as an afterthought.
Developers building telecom, TV, or set-top-box adjacent products who need one system spanning web and native mobile platforms with matching visual style.
It's fully open source, so the SDKs and component library can be adopted directly rather than only studied for visual reference.
Orange's UI framework, focused on accessibility and brand consistency.
