Screaming Frog Alternatives (2026): 10 Website Crawlers

Screaming Frog SEO Spider is one of the best-known website crawlers around, and plenty of people reach for it first. But it isn't the only way to find broken links, redirect chains, missing page titles and duplicate content. If you'd rather work in a browser, want clearer reports or just want to compare, there are plenty of other crawlers to look at.

This page lists ten Screaming Frog alternatives in no particular order, sorted alphabetically. I've mixed smaller, independent crawlers with a few well-known platforms. Everything below comes from each tool's own website, so check the current details before you commit. If you're new to the topic, my plain-English guide to technical SEO in digital marketing is a good place to start.

Website crawler alternatives side by side

A site crawler visits your pages the way a search engine bot does and reports what it finds. In the free plan column, Yes means the tool's own site describes a free version or free access. Trial only means a free trial with no permanent free option. No means I couldn't find either on its own site.

How to choose a site crawler for your website

A crawler's only useful if you'll read and act on what it finds. Start with the size of your site and who'll be using the tool, then work through these questions.

• How many pages do you have? A local business with fifty pages has different needs from a shop with thousands of product pages.
• Desktop or online? Desktop crawlers run on your own computer. Online crawlers run on someone else's servers and can schedule repeat crawls for you.
• Does it render JavaScript? If your pages are built with scripts, you want a crawler that can see what a visitor sees.
• How readable are the reports? Some tools hand you a giant spreadsheet. Others rank issues and explain each one in plain words.
• Can you schedule crawls and compare them? Seeing what changed since last week is more useful than a single snapshot.
• Can you export what you find? If you share results with a developer or client, check which formats the free version allows.

Which kind of crawler suits which website owner

• Free desktop crawlers suit freelancers and small business owners who crawl a site now and then and don't mind a plainer screen.
• Desktop tools with rich reports suit consultants who audit different client sites and want explanations built in.
• Online platforms suit teams that want scheduled crawls, shared dashboards and alerts when something breaks.
• Enterprise and log-analysis tools suit very large sites, where seeing how bots spend their time matters as much as the crawl itself.
• Suite-based audits suit anyone already working in a wider SEO toolkit who'd rather keep everything in one login.

What a good site crawl should tell you

Whichever tool you pick, the checks that matter most are fairly consistent. Look for a list of broken links and pages that return errors, redirects that bounce through several steps, missing or duplicated page titles and descriptions, pages blocked from search engines by accident, and slow or oversized pages. My step-by-step guide to finding and fixing broken links shows what to do with the first of those once you've found them.

A crawler only tells you what it can reach. It won't tell you whether Google has chosen to index a page, so pair your crawl with data from Google's own tools. My walkthrough of a Google Search Console SEO audit covers that side.

Setting up your first website crawl

1. Decide what you want to learn, such as broken links, missing titles or redirect problems, so you don't drown in results.
2. Start the crawl from your homepage and make sure the tool follows your sitemap too.
3. Set a sensible speed limit so the crawl doesn't slow your site down for visitors.
4. Sort the results by severity or by the number of pages affected, and fix the biggest problems first.
5. Fix a batch, then crawl again to confirm the issues have gone.
6. Save a copy of each crawl so you can compare it with the next one.

Mistakes people make when switching crawler

• Judging a tool on its issue count alone, when different tools define and group issues differently.
• Trying to fix every warning, including ones that don't affect how visitors or search engines see the site.
• Forgetting to check whether the free version limits the number of pages it will crawl.
• Crawling too fast and putting strain on a small hosting account.
• Treating a clean crawl as proof that a page will rank.

Do you make website crawling or technical SEO audit software? Tool makers can ask to be considered for a featured place on this list.

Making your final crawler shortlist

Pick two tools that suit your site size and working style. Run both on the same website and compare what they find, how clearly they explain it and how easily you can share the results. Keep the one you'll open again without being reminded. If you haven't got an XML sitemap yet, this free XML sitemap generator is a quick way to give any crawler a clean starting list.

Frequently asked questions

What is a website crawler used for?

A website crawler visits your pages like a search engine bot and reports what it finds, such as broken links, redirects, missing page titles, duplicate content and blocked pages. It helps you spot technical problems before they affect visitors.

Is there a free alternative to Screaming Frog?

Yes. Some crawlers on this page offer a free version or free access, though limits vary. Check each tool's own website for the current allowance, especially page limits and exports.

Do I need a desktop crawler or an online one?

Desktop crawlers run on your computer and suit occasional audits. Online crawlers can schedule repeat crawls and share results with a team. The right choice depends on how often you crawl and who needs to see the results.

How often should I crawl my website?

After any big change, such as a redesign, a move to a new address or a batch of new pages, and then at regular intervals. Scheduled crawls help busy sites catch new problems early.

Can a crawler tell me why my pages don't rank?

Not on its own. A crawler finds technical issues, but rankings also depend on content, competition and how search engines choose to treat your pages. Use it alongside Google's own tools.
