Helios, HashiCorp's new open source design system, offers a peek into how the company creates its product UIs. By establishing a standardized design language, HashiCorp aims to increase design quality with greater consistency across its product lines. The public launch of Helios is an active choice to deliver beautiful user interfaces and experiences across all customer-facing touchpoints. Helios gives designers and engineers a centralized repository of components that they can use to build inclusive, beautiful, and consistent user experiences. Engineers can leverage code samples and expert guidance to save development time and reduce unnecessary customization. The design system is built on atomic design principles, with plans to continue adding new icons, foundational components, and patterns to the library in the future.
