Ferret
For Mac · made by Marshmallow

Find every broken link before your visitors do.

Ferret crawls your site from your Mac. It checks every page, image, script and outgoing link, follows every redirect hop, and puts what is broken in front of your whole team.

From URL to fix list in minutes

  1. Step 1

    Add your site

    Paste the URL. Ferret checks that it is reachable, reads robots.txt and finds the sitemap before it starts.

  2. Step 2

    Crawl from your Mac

    Pages, images, scripts, stylesheets and outgoing links, eight requests at a time. Staging behind a password works too.

  3. Step 3

    Fix it together

    Results stream to your team while the crawl runs. Everyone sees the same broken links and where they sit.

Soon

One fix instead of fourteen.

Most broken links are not fourteen mistakes. They are one mistake in a footer, a menu or a translation table. Ferret groups the pages that link to a broken URL by where the link sits, so you fix the template once and the whole list clears.

Everything a link check should do

Every link, every hop

Internal pages, images, CSS, scripts, iframes and external links. A redirect chain shows each hop, not just where it ends.

Respects your rules

robots.txt, nofollow and your own exclude patterns, so filter and cart pages do not flood the results.

Staging included

The crawl runs on your Mac, so it reaches sites behind basic auth or your office network. Credentials never leave the Keychain.

Shared with your team

Invite colleagues. Every crawl, from any Mac, lands in the same place, with who ran it and when.

Export what you need

Filter to the problems and export a CSV for the developer, or work through them in the app.

Scheduled crawls and client reports

Soon

Weekly checks from our server, alerts when things break, and a clean report link to send your client.

Your site has broken links. Let’s find them.

Download the app, sign in, add a site. The first crawl usually takes a few minutes.
