Example crawl. Pick any problem to see the pages affected and what links to them.

Everything you need to clean up a site

Built for people who fix websites: agencies, freelancers, developers and in-house marketers.

Ranked by what matters

Problems are sorted by priority and how many pages they hit, so you always know what to do next.

Unlimited URLs

Crawl a 50 page brochure site or a huge online shop. There's no cap, and big crawls can pause and resume.

See what changed

Each crawl is compared with the last one, so you can show what's been fixed and catch anything new.

Show it on the page

Open any page with its problems outlined in place: broken links, missing alt text, small tap targets and spelling mistakes.

Sitemap and link audit

Find orphan pages, sitemap entries that shouldn't be there and important pages missing from it.

Command line and CI

Run crawls from a script, export CSVs, and fail a build when high-priority problems appear.

Works with Claude

Connect Crawl Master to Claude in one click and ask it to run crawls, explain problems and suggest fixes.

Fast

Uses every core on your computer. On a fast PC it gets through more than 500 pages a second.

Private by design

Crawls stay on your computer. No tracking, no cloud account, nothing uploaded.

Questions

How does the free trial work?

Download the app and use every feature for 14 days. You don't need to give card details. When the trial ends, you can still open and export the crawls you saved. Starting new crawls needs a licence.

Is it a subscription?

No. You pay once and the licence is yours. It includes updates and email support.

How many computers can I use it on?

A licence is for one person, and they can use it on any number of computers they own or control. A business buying for several people needs one licence per person.

What if it's not right for me?

Email josh@higginsdevelopment.co.uk within 30 days of buying and you'll get a full refund. See the terms and refund policy.

Which systems does it run on?

Windows 10 and 11 today. A Mac version is on the way.

Can I bring in crawls from another tool?

Yes. You can import a Screaming Frog "Internal: All" CSV export and see it in Crawl Master's issues-first view.

Does it send my data anywhere?

No. Crawls are stored on your computer. The app only checks your licence key about once a week. Optional connections, like Google Search Console, use your own accounts and go straight from your computer to that service. See the privacy policy.

Who makes it?

Crawl Master is made by Josh Higgins at Higgins Development, a small software business in the UK. Questions go straight to him at josh@higginsdevelopment.co.uk, and he usually replies within 2 working days.
