  1. Cookie-free traffic analytics combined with continuous accessibility, Core Web Vitals, security, GDPR and carbon audits that turn findings into tracked issues.

    Prelumen Analytics puts visitor statistics and a website health check in the same dashboard. It counts traffic without cookies and honours Do-Not-Track by default, then keeps auditing the site in the background so problems surface as tracked issues with a re-test instead of a one-off report.

    The platform pairs real-time traffic, visitor journeys, funnels and revenue attribution with checks across accessibility, SEO, security, performance, GDPR and carbon. Core Web Vitals come from real visitors, not lab runs. Usage is metered in monthly tokens, with a free plan that needs no card and paid tiers adding AI summaries and MCP access for agent workflows.

    Key benefits:

    • Cookie-free analytics with traffic, journeys, funnels and revenue attribution
    • Accessibility checks using PhpAlly and WAVE to catch WCAG problems
    • Real-user Core Web Vitals showing how fast pages load for actual visitors
    • Security audits of headers and certificates, plus a malware scan
    • GDPR checks covering privacy policy, consent setup and active trackers
    • Carbon per pageview with simple and detailed footprint checks
    • Broken link and SEO checks running continuously, not once a quarter
    • Issue tracking with re-tests so a fix is confirmed rather than assumed

    Prelumen is operated by onEco GmbH, registered in Berlin, Germany, and processes data in the EU. The application runs on Heroku in its Ireland region with a database service on AWS, and Cloudflare in front, so the data stays in EU datacenters but on US-owned infrastructure. Visitor data is not sold to ad networks.

    Ideal for agencies and site owners who want traffic numbers and a running quality audit without adding a consent banner.

  2. Automated HTML and accessibility testing for large websites. Check thousands of pages against WCAG guidelines and W3C standards using Axe Core and W3C Validator in minutes.

    Spanish tool that audits thousands of pages at once for HTML errors and accessibility, running Axe Core and the W3C Validator against WCAG and W3C standards.
