Run the audit →Why free?
Each tool here is a piece of PeakKR running without the login. The redirect tracer is the same code our site audits use; the pixel measurement is what our on-page editor enforces. We publish them because they're genuinely useful on their own — and because some of the people who use them run agencies.
Want these tools on every page you visit? The PeakKR SEO Assistant for Chrome puts the whole kit one click from your toolbar — on-page x-ray, broken links, Core Web Vitals, live tag inspection and more.
