Moz Pro vs Screaming Frog SEO Spider
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedMoz Pro compared with Screaming Frog SEO Spider
These are complements. Screaming Frog is a desktop crawler that will interrogate a site far more forensically than Moz Site Crawl ever will, for a flat annual licence with no monthly index subscription. Moz supplies the link index, keyword data, and ongoing monitoring that a desktop crawler cannot. Technical SEOs run both; a small business doing basic hygiene can start with Moz alone.
Screaming Frog SEO Spider compared with Moz Pro
Different halves of the same job. Moz Pro brings the link index, keyword data, authority metrics, and ongoing monitoring that Screaming Frog cannot; Screaming Frog crawls far more forensically than Moz Site Crawl ever will, for a flat $279 a year with no page limits. Screaming Frog even pulls Moz link metrics into the crawl through the API. Most technical teams run both, and the combined cost is still below one Ahrefs subscription.
Choose Moz Pro if
Small businesses, freelancers, and in-house marketers who want a complete, understandable SEO suite with a credible backlink index for under $100 per month, and developers or agencies who need cheap programmatic access to link metrics through the Moz Links API.
Choose Screaming Frog SEO Spider if
Technical SEOs, developers, agencies, and anyone responsible for a site's technical health who wants a forensic crawler with a flat annual cost and no metering, alongside whatever hosted SEO platform they already pay for.

|---|---|---|
| Category | SEO | SEO |
| Starting price | $49 per month (Starter), or $39 per month billed annually (free plan available) | Free up to 500 URLs, then $279 per licence per year (free plan available) |
| Pricing model | Self-serve tiered subscription metered per campaign on tracked keywords and pages crawled, with published per-unit overage pricing and a separately sold row-based Links API. | Flat annual per-licence software fee with unlimited crawling, no credits and no metered index, plus a separately licensed Log File Analyser and progressive volume discounts. |
| Free plan | No free Moz Pro plan, but a free Links API tier of roughly 50 rows per month, free public tools including Domain Analysis and MozBar, and the Moz Academy training library. | The free version crawls up to 500 URLs and retains most core features including broken link detection, metadata analysis, XML sitemap generation, and Google Analytics and Search Console integration. |
| Free trial | Free trial offered on the Standard and Medium monthly plans | No |
| Best for | Small businesses, freelancers, and in-house marketers who want a complete, understandable SEO suite with a credible backlink index for under $100 per month, and developers or agencies who need cheap programmatic access to link metrics through the Moz Links API. | Technical SEOs, developers, agencies, and anyone responsible for a site's technical health who wants a forensic crawler with a flat annual cost and no metering, alongside whatever hosted SEO platform they already pay for. |
| Setup time | About thirty minutes. Create a campaign, verify the site, connect Google Analytics and Search Console, add competitors and target keywords, and start the first Site Crawl. Larger sites take longer to crawl but nothing needs configuring while they do. | Ten minutes to install and run a first crawl. Configuring it properly for a large or JavaScript-heavy site, including rendering, storage mode, exclusions, and API connections, takes a couple of hours the first time and is then reusable as a saved configuration. |
| Learning curve | The gentlest of the major suites. Moz's whole design philosophy is making SEO legible to non-specialists, and Priority score, DA, and the issue-severity grouping in Site Crawl are all built for people who need a defensible next action rather than a raw dataset. | Steep for a non-specialist and shallow for anyone who already understands technical SEO. The interface presents raw data rather than recommendations, which is exactly what an expert wants and exactly what a marketer without a technical background will find impenetrable. |

Strengths and limitations
Moz Pro
Strengths
- The best value among established SEO suites, with a full toolkit from $39 per month billed annually against $129 or more for comparable competitors.
- AI Visibility is included on every plan rather than sold as a $199 to $699 add-on, which as of 2026 is a genuine competitive advantage.
- The Moz Links API starts around $20 per month for 3,000 rows, making it the only realistically priced backlink API for small businesses and independent developers.
- Published, granular overage pricing at $10 per campaign, $15 per 50,000 pages, and $20 per 200 keywords means you extend a plan rather than jump a tier.
Limitations
- Organic search only. No advertising research, no display or social intelligence, and no market traffic analytics, so it does not replace Semrush for a cross-channel marketer.
- The keyword database and historical depth are smaller than Ahrefs' or Semrush's, which matters for competitive analysis in crowded verticals.
- Domain Authority is widely misused as a goal rather than a diagnostic, and Moz's marketing has never worked very hard to discourage that.
- Moz Local is priced per location and sold separately, which makes multi-location businesses substantially more expensive than the Moz Pro sticker price suggests.
Screaming Frog SEO Spider
Strengths
- Flat $279 per year with unlimited crawling and no metering anywhere, against hosted crawlers that ration pages per month inside far more expensive subscriptions.
- More than 300 detected issue types with genuinely forensic depth, including canonical, hreflang, directive, and structured data analysis that hosted auditors summarise rather than expose.
- Headless Chromium rendering makes it one of the few tools that will audit a modern JavaScript application honestly.
- Custom extraction with XPath, CSS selectors, and regex turns it into a general-purpose site data extractor, which is why non-SEO teams end up using it too.
Limitations
- It owns no index. No keyword data, no backlink data, no rank tracking, and no competitive research, so it is always a second tool rather than a first one.
- The interface is a dense spreadsheet with no health score and no prioritised action list, which makes it hostile to non-technical users.
- Unlimited crawling is bounded by your own hardware, and large crawls require configuring database storage mode and having the memory and disk to back it.
- No hosted dashboards, no client portal, and no white-label reporting; output is exports and spreadsheets.
Pricing compared
Moz Pro
Self-serve tiered subscription metered per campaign on tracked keywords and pages crawled, with published per-unit overage pricing and a separately sold row-based Links API.
- Starter$49
- Standard$99
- Medium$179
- Large$299
Moz Pro is the best price-to-capability ratio among the established suites, and it is not close. Standard at $79 annually gives you a 40-trillion-link index, 300 tracked keywords, 400,000 crawled pages, and AI visibility tracking for roughly what one additional Ahrefs seat costs. The overage model is honest, the annual discount is a real 20 percent, and the Links API at $20 per month is the only affordable programmatic access to a major backlink index anywhere in the market. What you give up is depth and breadth: a smaller keyword database, no advertising or social intelligence, no content editor, and local sold separately. If your SEO work is fundamentals done consistently rather than competitive intelligence done exhaustively, Moz is the rational purchase and the money you save is better spent on content.
Screaming Frog SEO Spider
Flat annual per-licence software fee with unlimited crawling, no credits and no metered index, plus a separately licensed Log File Analyser and progressive volume discounts.
- Free$0
- SEO Spider licence$279
- SEO Spider volume licensing$265 to $235
- Log File Analyser$139
Screaming Frog is the best value purchase in this entire category, and the comparison is not close because it is not the same kind of purchase. $279 per year buys unlimited crawling forever, against hosted auditors metering 250,000 or 2 million pages per month inside subscriptions costing four to twenty times as much. A ten-person agency licences everyone for $2,490 a year, roughly what one Ahrefs Advanced seat plus its per-user surcharge costs over the same period. The reason the price can be this low is that Screaming Frog owns no index and rents you no data; it sells you a program that runs on your machine. That is also its limitation. You still need a keyword and backlink subscription somewhere, and the correct way to think about this is that the crawler is the cheap part of your stack that should never have been a subscription in the first place.
Editorial verdict on each
Moz Pro
Moz Pro is no longer the tool that defines the category, and it has stopped pretending to be. What it is instead is the most sensibly priced complete SEO suite on the market: a 40-trillion-link index, credible authority metrics that need no explanation in a client meeting, honest published overage pricing, a 20 percent annual discount, AI visibility included rather than upsold, and a Links API starting at $20 per month when the nearest equivalent is reported at $500. The tradeoffs are clear and you should take them seriously if they apply to you: a thinner keyword database, no advertising or social intelligence, no content editor, and local listings sold separately per location. For a small business, a freelancer, or an in-house marketer who is accountable for organic traffic and not running a competitive intelligence operation, Moz is the rational default and the several hundred dollars a month you do not spend on Ahrefs is better spent on the content itself.

Screaming Frog is the tool in this category whose pricing makes the most sense, because it is honest about what it is selling. There is no index to rent, so there is nothing to meter, so a licence costs $279 a year and crawls as much as your laptop can handle. Set that against hosted auditors rationing 250,000 pages a month inside subscriptions costing several times more and the arithmetic barely needs stating. What you get is genuinely forensic: headless Chromium rendering that audits JavaScript applications honestly, custom extraction with XPath and regex, scheduled crawls and command line operation, crawl comparison for demonstrating progress, and in 2026 the option of running AI prompts against your pages using a local model so nothing leaves your network. What you do not get is any data of its own, any dashboard, or any help for a non-technical user. Buy it as the crawler in a stack that already has a keyword and link subscription somewhere else, start with the free 500-URL version, and licence the whole team when you outgrow it.
