What each one
is actually better at

We are not going to pretend Screaming Frog SEO Spider is bad. It is not. Here is the honest split.

Where SlapMyWeb wins
  • Runs in the browser with no download and no crawl configuration: paste a URL and get a scored audit back.
  • Turns findings into a verdict: 240+ checks scored into 8 weighted pillars, a plain-English summary and a prioritized action plan.
  • Generates fix code for each issue, where Screaming Frog exports data you then have to interpret and act on yourself.
  • Covers performance, security, accessibility, mobile and conversion heuristics in one report written for clients and developers, not only for SEOs.
  • Produces client-ready deliverables out of the box: PDF, CSV, XLSX and DOCX exports, share links and scheduled reports by email or Slack.
  • Bundles keyword research, rank tracking and domain analytics on Pro at $9/mo, which a crawler does not provide.

Where Screaming Frog SEO Spider wins

  • The reference desktop crawler for technical SEO: it can crawl very large sites, limited only by the machine's memory and storage on a paid licence.
  • Deeply configurable, with custom extraction, crawl comparison, JavaScript rendering and fine control over what the spider follows.
  • A free version that crawls up to 500 URLs, which is enough for many small sites and quick checks.
  • Integrates with Google Analytics, Search Console and PageSpeed Insights, and can crawl with OpenAI and Gemini for custom analysis.
  • Inexpensive for what it does: around ~$279 per year per licence, with bulk discounts for teams.

We keep this section honest on purpose. Screaming Frog SEO Spider is a good tool with real advantages — pick the one that fits the job in front of you.

The detail

How they differ
once you look closely

Screaming Frog vs SlapMyWeb: different tools for different moments

Screaming Frog SEO Spider is the crawler most technical SEOs learn on. It is a desktop application that walks a site link by link and records everything it finds: status codes, redirects, titles, meta descriptions, canonicals, directives, hreflang, response times and much more, all sortable, filterable and exportable. It is a power tool, and it expects you to know what to look for. SlapMyWeb works the other way around. It runs in the browser, needs no setup, and answers a narrower question: how healthy is this site, what should be fixed first, and what does the fix look like? You get 240+ checks scored into 8 weighted pillars, a plain-English verdict, a prioritized action plan and generated fix code for each issue. Neither replaces the other. Screaming Frog gives an expert the raw material for any analysis they can think of. SlapMyWeb gives anyone, including people who have never configured a crawler, a finished audit.

Raw crawl data versus a finished report

The biggest practical difference is what happens after the crawl. Screaming Frog hands you data. Its issues and opportunities lists are useful, and custom extraction lets you pull almost anything out of the HTML with XPath, CSS selectors or regex, but turning a crawl into a client deliverable is your job: filtering, deciding priorities, writing it up. That flexibility is why experts love it. SlapMyWeb does the interpretation step for you. Each scan is scored across Speed (20%), SEO (18%), Security (15%), Mobile (12%), Design (10%), Accessibility (10%), Best practices (8%) and Content (7%), and deep-audit modules cover accessibility against WCAG 2.2 AA with axe-core, security and compliance, schema validation, Core Web Vitals from PageSpeed Insights v5 and CrUX field data, rendering, image, video and entity SEO, conversion heuristics, crawl budget and tracking setup. The report exports to PDF, CSV, XLSX or DOCX, can be shared by link, and can be scheduled to arrive by email or Slack.

Pricing: a cheap annual licence against a free tier

Screaming Frog is good value. The free version crawls up to 500 URLs, and a paid licence costs around ~$279 per year per user on its pricing page, with bulk discounts for five or more licences. Screaming Frog says the licence removes the 500-URL limit, with the real ceiling set by your machine's memory and storage, and opens up saving crawls and the spider's full configuration. For a working technical SEO, that is one of the cheapest serious tools available. SlapMyWeb is free indefinitely at 10 scans a day with every issue listed, and anonymous visitors get 3 scans a day. Pro at $9/mo unlocks full fix code, clean PDFs, keyword research, rank tracking and domain analytics; Agency at $29/mo adds white-label PDFs, bulk scanning, multi-client workspaces, backlink analytics and local SEO. On price alone the two are close. What differs is what the money buys: crawl capacity and configurability from Screaming Frog, interpretation, fix code and reporting from SlapMyWeb.

Who each tool fits

Screaming Frog fits technical SEOs, in-house teams and agencies doing site-wide analysis: migrations, large e-commerce catalogs, redirect mapping, finding orphan or duplicate pages, and any custom question that needs data from every URL. Its Google Analytics, Search Console and PageSpeed Insights integrations let you join crawl data with traffic and performance data from your own accounts. SlapMyWeb fits people who need an answer rather than a dataset: developers who want the fix, founders checking their own site, freelancers running pre-sales audits, and agencies sending regular health reports across many client sites. Its outside-in approach means it does not see your Search Console data, and it is not built to crawl a 100,000-URL site page by page. SlapMyWeb is also a young product, launched in 2026, against a crawler with a long track record in the industry. Many SEOs will reasonably keep Screaming Frog for deep crawls and use SlapMyWeb for the scored summary a client or developer can act on.

The bottom line

If you need to crawl a whole site, interrogate every URL, extract custom data or audit a migration, Screaming Frog SEO Spider is the right tool, and SlapMyWeb does not compete with it on crawl scale or configurability. If you need a scored, readable audit with a prioritized plan and generated fix code, without installing or configuring anything, SlapMyWeb is faster to an answer and easier to hand to someone else. It also adds keyword research, rank tracking and white-label reporting that a crawler does not include. The two work well together: crawl with Screaming Frog when you need the full dataset, scan with SlapMyWeb when you need the summary and the fixes. To see the difference on your own site, run a free SlapMyWeb scan next to a Screaming Frog crawl and compare what each one leaves you to do next.
