Stark

Stark is an accessibility toolkit that plugs directly into Figma, Sketch, and Adobe XD so design teams can catch contrast, color-blindness, and readability issues before a single line of code is written. Instead of treating accessibility as a post-launch audit, Stark surfaces WCAG-level contrast scores right inside the design canvas, lets designers simulate eight forms of color blindness on live artboards, and flags text that will be too small or too low-contrast to read comfortably. A companion Chrome extension and API extend the same checks to shipped websites, so engineering teams can validate production pages against the same standards designers used upstream. Stark's focus/tab-order visualizer helps teams reason about keyboard navigation without opening dev tools, and its reporting features let design system owners track compliance across dozens of components over time. It's built for product teams that want accessibility to be a default part of the design process rather than a compliance checkbox added at the end, and it's become a standard plugin inside many startup and enterprise design systems alike. Free and paid team tiers make it approachable for a solo designer while still scaling to organizations running accessibility programs across many product surfaces, with shared libraries and admin controls for consistency.
