VertaaUX builds tools for automated UX, accessibility and conversion audits. We help teams catch issues early with actionable reports and developer-friendly workflows.
We built VertaaUX to close an accessibility gap in AI: an automated UX and accessibility audit platform that scores any URL across seven categories in seconds. One command in your terminal. One MCP server in your AI agent. One CI gate in your pipeline. We started because Lighthouse covers performance but nothing covered UX and accessibility with the same speed and depth. Now we serve developers, agencies, and compliance teams across the EU who need to ship accessible products without slowing down. Based in Helsinki. Open source CLI. MIT licensed MCP server.
