If you've searched for ways to audit your website, you've probably come across both Screaming Frog SEO Spider and AuditCrow. They're both audit tools, but they're built for very different audiences. Here's a clear comparison so you can pick the one that suits your situation.
First, the honest version
Screaming Frog does things AuditCrow's free scan does not. It crawls entire sites - hundreds or thousands of pages in one run - maps redirect chains, finds site-wide duplicate content, and integrates with Google Analytics and Search Console. The free AuditCrow scan audits one page at a time: it is the taster for the full AuditCrow platform, which audits sites as a whole and is in beta with no paid plans published yet. If your job today is a whole-domain technical crawl, Screaming Frog is the right tool and we would rather tell you that than waste your afternoon.
What AuditCrow does differently is everything around the findings: plain-English explanations, prioritisation by impact and effort, and AI-readiness checks that a traditional crawler doesn't run. You don't have to take that on trust - we publish a real, unedited AuditCrow report so you can judge the output before running anything.
What Is Screaming Frog SEO Spider?
Screaming Frog SEO Spider is a desktop application - software you download and install on your computer (Windows, Mac, or Linux). Once installed, you give it a starting URL and it crawls your site: visiting page after page, following links, and collecting data on every URL it finds. The result is a detailed spreadsheet-style output covering title tags, meta descriptions, response codes, redirect chains, and much more.
It's the tool of choice for many professional SEOs and web developers. The free version crawls up to 500 URLs. A paid licence removes that limit and unlocks JavaScript rendering, advanced configuration, and integrations with Google Analytics and Search Console.
What Is AuditCrow?
AuditCrow is a browser-based audit tool. No download, no installation, no account required. You enter a URL and within a minute you receive a prioritised, plain-language report covering structure, SEO, speed, content, trust, accessibility, and AI readiness.
Every finding comes with:
- A plain-English explanation of what the issue is and why it matters
- A difficulty rating (Easy, Medium, Hard) so you know where to start
- The exact message to send your web person if you don't want to fix it yourself
See a complete example report - it's a real scan of a real business site, published unedited with the domain anonymised.
The Key Differences
| | AuditCrow (free scan) | Screaming Frog | |---|---|---| | Setup | Browser only, no install | Download required | | Audience | Business owners, marketers | Technical SEOs, developers | | Output | Plain-language prioritised report | Detailed spreadsheet / raw data | | Pages per scan | Single page | Up to 500 free, unlimited paid | | AI readiness checks | Yes - built in | No | | Signup required | No | No (free); email for paid | | Cost | Free | Free (500 URLs) / paid licence |
And the full platform? The fairer comparison with a paid Screaming Frog licence is the AuditCrow platform (in beta): site-wide audits scored on a completable 0 to 1000 Foundations Index, connected Search Console and Analytics data, six specialist AI analysts, weekly monitoring, and an action plan steered by your goals - all in plain English rather than spreadsheets. Screaming Frog still goes deeper on raw technical crawling; the platform's job is telling a business owner what to do about it. No paid plans are published yet - the waitlist gets first access.
When to Choose AuditCrow
- You're a business owner or marketer who wants actionable advice without wading through raw data.
- You need a fast health check on a specific page: your homepage, a key landing page, or a page you've just updated.
- You want findings someone non-technical can act on - see what the report looks like first.
- You don't want to install software or create an account - just get results.
When to Choose Screaming Frog
- You're a developer or technical SEO comfortable working with large datasets.
- You need to crawl hundreds or thousands of pages in one session to find site-wide issues.
- You want to cross-reference crawl data with Google Analytics or Search Console exports.
- You need to map redirect chains or find duplicate content patterns across your whole domain.
Can You Use Both?
Yes. Many teams use Screaming Frog for large-scale technical crawls and AuditCrow to quickly check individual pages before launch or after a fix - without needing to install anything or be a technical expert. They solve different problems at different moments.
If you're just getting started with website auditing and want to understand what issues your site has without a steep learning curve, AuditCrow is the faster, friendlier place to begin.
