Free tools

The eleven public Metric Vault tools you can run without an account, plus the Chrome extension, and where each one leads next.

Last updated 2026-08-06

Summary#

Metric Vault publishes eleven SEO and AI-search tools at /free-tools that anyone can run in a browser with no account, no card and no usage cap. Each one fetches your live page and reports what it actually found. This page routes you to the right tool and to the in-app version of the same capability.

Overview#

The free tools all work the same way. You enter a domain or URL, we fetch the live page (and, where relevant, its robots.txt, llms.txt or sitemap.xml), parse what came back, and show a result on the same screen. Nothing is stored against you, because there is nothing to store you against.

They are grouped below by the question they answer. If you want the reasoning behind what is and is not included, read Free tools, no account needed.

Where to go after a free run#

Every free tool ends with a link into the product, because the free tools measure a page while the app measures a site over time. The nearest in-app equivalents are Site Audit, Advanced Technical Checks, Visibility Overview and Domain Overview. What a signed-in Free account adds is covered in What you get on Free, and the credit model behind the paid tools is in How credits work.
