How the composite score works

The overall score is a weighted average: Visual 18.75%, Accessibility 25%, Buttons and links 31.25%, Under the hood 12.5%, and Mobile 12.5%. Unassessed categories are excluded and the remaining weights are normalized.

Product categories start at 100. Each distinct verified finding deducts 30 points for a reproduced flow defect, or 18 for critical, 12 for high, 7 for medium, and 3 for low stored detector severity. Scores stop at zero and round to whole numbers. All verified findings count, including those beyond the displayed list. The formula is fixed and versioned, so the same saved evidence always receives the same score.

Primary buttons fail the AA contrast threshold

The primary call to action buttons on the project render white 14px text on the #1d9bf0 brand blue, a contrast ratio of 3:1 against the 4.5:1 required by WCAG 2.1 AA for text at that size. This affects the header "Get Started" link and the "Start Free Trial" button on the home page, and the same pattern repeats on /pricing, /about, /docs and /contact. The grey uppercase labels such as "Without XBurst" in the comparison cards fail the same check. axe-core classes the color-contrast rule at serious impact.

A rough edge in the layout

The hero headline wraps a single-character word onto its own line between the first and second lines, leaving an orphaned line in the middle of the heading.
