Elisa Design System (EDS) is the shared framework behind the Finnish telecom Elisa's digital products, pairing a Figma library and design tokens with a React component library used across dozens of internal products.
It runs automated visual regression tests on every single change, a rigor most public design systems don't document, catching visual breakage before it ships rather than relying on manual review.
Design system engineers wanting a concrete example of automated visual regression testing built into a real production system's workflow.
The system also documents Figma "ways of working" (file structure, naming conventions), useful reference material for teams standardizing their own Figma practices.
Elisa's shared design system, keeping its products visually consistent.
