Which Umbraco version is that site running?

Enter a website address. We'll scan its public pages, work out which version of Umbraco it uses, and show whether it's still supported, when it reaches end of life and which versions you can upgrade to.

We only load public pages, exactly like a browser does. We never log in or test for weaknesses.

How it works

A quick, polite, public scan.

  1. 01

    Home page

    We look for Umbraco's fingerprints: its media URLs, package folders and server headers.

  2. 02

    Modern backoffice

    Umbraco 14 and later publish a status endpoint and a versioned backoffice manifest, often revealing the exact version.

  3. 03

    Classic backoffice

    Umbraco 7 to 13 use an AngularJS backoffice and endpoints that tell those versions apart.

  4. 04

    Your options

    We match the result against Umbraco's official support dates and show where you can upgrade to.

Results are an informed estimate. Some sites hide their version, so we always show how confident we are and why. If you own the site, your backoffice shows the exact version under Help › System information.

Umbraco support dates

Every Umbraco version and its end-of-life date.

After the end-of-life date a version gets no more security fixes. Long-term support (LTS) versions are supported for three years; standard-term (STS) versions for one.
