A real client site had its main heading in white-on-white text for weeks.
Every SEO tool said the page was fine, because they read source code, not the rendered page. That bug became RenderAudit: it loads your site in a real browser, computes actual contrast on every element, and shows a health score in ~15 seconds (free, no signup, subs). Available on Claude/AI chats via MCP.
RenderAudit loads your site in a real headless browser and audits what visitors actually see - invisible text, WCAG contrast failures (with element screenshots), broken links, missing social tags. Free scan in seconds; full report $15, no subscription, no sign ups, no BS.
