Stark runs accessibility checks directly inside Figma, Sketch, and the browser: contrast checking, color blindness simulation, focus order, and alt text management.
Checking accessibility inside the design tool itself, rather than after handoff, catches contrast and color-blindness problems while a design is still editable, instead of after a developer has already built it.
Design teams wanting accessibility checks built into their actual workflow, not a separate step run by someone else after the design is finished.
The free tier covers contrast checking and color blindness simulation, which handles most day-to-day needs. Pro ($99/year) is worth it specifically for focus order and alt text management on a real product team.
A colour-blindness simulator to test your designs for accessibility.
