Stark

What is Stark?

Stark is an accessibility toolkit that plugs directly into design tools like Figma and Sketch, plus browser extensions and a standalone app, so contrast ratios, color blindness simulation, and missing alt-text get flagged while a design is still being made rather than after it ships to code. Catching issues at the design stage means fixes are a color swap or a copy tweak instead of an engineering ticket filed weeks later.

Key features

• Contrast checking built directly into the Figma/Sketch canvas, checked against WCAG AA/AAA thresholds as you design
• Color blindness simulation to preview a design under different types of color vision deficiency
• Alt-text and annotation tools so accessibility notes travel with the design file into handoff, not just verbally to engineers
• Browser extension for auditing live, already-shipped websites, not just design files
• Team-wide reporting to track accessibility issues across a whole design system rather than one screen at a time

Who it's for

A good fit for design teams that want to shift accessibility left, catching contrast and readability problems before a single line of frontend code is written. It complements rather than replaces code-level accessibility testing (screen reader behavior, keyboard navigation, semantic HTML), which still needs to be checked separately in the built product.

Pricing

Free tier with core checks for individuals, with paid team plans for organization-wide accessibility workflows and reporting.
