Let's picture this scenario: we launch a website with perfect buttons and great contrast. Later down the road, unaware of the accessibility implications, we change the background of sections of the website. This might make some buttons fail contrast with adjacent colors. Add this tool to your workflow and prevent going live with less-than-perfect buttons.

Each time you scan a page, we store the results in a unique URL. You can send it to your team or save it for future comparisons.
