OnCrawl is a technical SEO crawler built for large, complex websites — the kind of tool used when Screaming Frog’s desktop crawler starts hitting practical limits on sites with hundreds of thousands of URLs. Its own materials cite crawling over 300 million URLs and processing over 500 million log lines daily. Here’s what it does, who actually needs it, and the one thing every roundup of this tool gets wrong: the price.
Quick Verdict
OnCrawl is right for enterprise sites — ecommerce catalogs, publishers, large B2B sites — where crawl budget and log file analysis genuinely change SEO outcomes at scale. It is not a tool to compare against a $29/month SEO suite; it’s sold to a different buyer entirely, and pretending otherwise is where most comparisons of this category go wrong.
- G2 rates it 4.4/5 with an 8.9/10 support score — genuinely strong
- Log-file analysis and cloud crawling solve real problems a desktop crawler can’t at enterprise scale
- Pricing is a universal complaint across G2, Capterra, and TrustRadius — no published number at all
- Takes real time investment to master the advanced features
Pricing: Quote-Only, and That’s the Real Answer
OnCrawl does not publish pricing. There is no price list on its site — you book a demo and go through a sales conversation. This isn’t an oversight on OnCrawl’s part or a gap in our research. It’s standard practice for software sold to enterprise procurement rather than to an individual with a credit card, and it’s worth taking at face value rather than guessing at a number.
What quote-only pricing signals in practice: a sales conversation, a contract term likely measured in years rather than months, and a floor price that assumes a team budget rather than a personal one. If you’re comparing OnCrawl to Screaming Frog on “value,” the comparison itself is the mistake. One is a $279/year desktop licence, the other is a five-figure-and-up enterprise contract. No roundup that lists them side by side on a pricing table is telling you the truth about either.
Do you actually need OnCrawl?
OnCrawl doesn’t publish prices, so this isn’t a cost calculator — it’s a fit check against the site sizes where a desktop crawler stops being enough, using Screaming Frog’s published tiers as the comparison point.
Method: uses only figures this review could verify. Screaming Frog is free up to 500 URLs and $279/year unlimited beyond that. OnCrawl publishes no pricing at all — it’s quote-only, enterprise-sales software, generally a five-figure-and-up annual contract per this review’s research. The article’s own guidance is that OnCrawl starts becoming relevant once a desktop crawler is “genuinely impractical” on your hardware — hundreds of thousands of URLs, not tens of thousands — but there’s no single published threshold, so 100,000 URLs is used below only as the point where it’s worth requesting a quote to compare, not a real breakpoint OnCrawl has published.
Real-World Use Cases
- An ecommerce catalog with hundreds of thousands of product URLs uses OnCrawl's log file analysis to see exactly which category and product pages Googlebot is actually spending crawl budget on, then prunes low-value URLs eating that budget.
- A publisher with a large, constantly-growing archive runs scheduled recurring crawls to catch technical regressions — broken internal links, orphaned pages, duplicate content — before they compound across tens of thousands of articles.
- A small site owner evaluating "enterprise SEO tools" out of curiosity requests a demo, discovers the sales process and likely five-figure contract, and correctly concludes Screaming Frog's free or $279/year tier already covers their needs.
What OnCrawl Does
OnCrawl runs cloud-based crawls, so it isn't limited by your local machine's memory the way desktop crawlers are. It also cross-references crawl data with log files and Google Search Console data. That combination shows you what your site's structure looks like and how Googlebot actually behaves on it.
| Feature | Why it matters |
|---|---|
| Cloud-based crawling | Handles enterprise-scale sites without local hardware limits |
| Log file analysis | Shows actual Googlebot crawl behavior, not just simulated crawl data |
| Crawl + data cross-referencing | Combines structure, rankings, and crawl budget data in one view |
| Scheduled recurring crawls | Tracks technical SEO health over time, not just a one-off snapshot |
Who Actually Needs This
OnCrawl is built for large sites — ecommerce catalogs, publishers, and enterprise sites where crawl budget and log file analysis genuinely change SEO outcomes. For a small site (under a few thousand URLs), a free tool or Screaming Frog's free tier covers the same technical-audit ground without the enterprise sales process or the price tag behind it.
OnCrawl vs. Screaming Frog
Screaming Frog is a desktop crawler, dramatically cheaper, and sufficient for small-to-mid-size sites — free to 500 URLs, $279/year unlimited, with no credits or crawl budget metering. OnCrawl is cloud-based, handles far larger sites without local hardware constraints, and adds log file analysis Screaming Frog doesn't natively provide. The choice comes down to two questions. Is your site genuinely large enough that a desktop crawler can't keep up? And do you have, or can you get, a budget that supports an enterprise sales conversation rather than a credit card checkout? If the answer to either is no, Screaming Frog is very likely the right tool, not a downgrade from OnCrawl. See our Screaming Frog vs OnCrawl capsule for the short version of this same call.
Pros and Cons
| Pros | Cons |
|---|---|
| Log file analysis shows actual Googlebot behavior, not just simulated crawl data | No published pricing — every prospective buyer must go through a sales conversation to get a number |
| Cloud-based crawling handles enterprise-scale sites without local hardware limits | Almost certainly a bad fit, financially, for anything under hundreds of thousands of URLs |
| Cross-references crawl data with GSC and log files in one view | No self-serve trial or checkout — evaluating it requires committing time to a demo |
| Scheduled recurring crawls track technical health over time, not just a one-off snapshot | Contract terms are likely measured in years, not months, unlike most SaaS tools reviewed on this site |
Detailed Analysis
Quote-only pricing is a filter, not a flaw
It's tempting to treat OnCrawl's lack of published pricing as a transparency problem, the way it would be for a $30/month SaaS tool. It isn't. For enterprise software sold through a sales team to a procurement process, quote-only pricing is standard practice. It functions as a filter: if you're not the kind of buyer who can sit through a sales conversation and sign an annual contract, the product isn't asking for your business in the first place. The honest takeaway isn't "OnCrawl is hiding something," it's "OnCrawl isn't selling to you unless you're already the kind of buyer this applies to."
The real comparison point is crawl budget, not price
Every roundup that puts OnCrawl next to Screaming Frog on a pricing table is answering the wrong question. The actual decision point is whether your site is large enough that crawl budget and log file behavior are genuinely limiting factors in your SEO outcomes — something that shows up around the hundreds-of-thousands-of-URLs mark, not tens of thousands. Below that threshold, Screaming Frog's desktop crawler does the same technical-audit job for a fraction of the cost, and OnCrawl's cloud infrastructure and log analysis simply aren't solving a problem you have yet.
Our Rating, and How We Reached It
| Criteria | Score | Why |
|---|---|---|
| Feature depth for enterprise-scale sites | 9/10 | Log file analysis and cloud crawling genuinely solve problems a desktop crawler can't at hundreds of thousands of URLs. |
| Pricing transparency | 3/10 | No published pricing anywhere — every buyer starts from zero information on cost, standard for the category but still a real limitation. |
| Fit for small-to-mid sites | 2/10 | Actively the wrong tool below enterprise scale; Screaming Frog covers the same ground for a fraction of the cost. |
| Evaluation friction | 4/10 | No self-serve trial — assessing fit requires committing to a demo and sales conversation before seeing real numbers. |
Overall: 8.0/10 for its actual target buyer (large-site enterprise SEO teams); not a fair comparison target for anyone else. Scored against its stated capabilities and category norms — quote-only pricing is standard for enterprise software and penalized only lightly here, since it's expected rather than deceptive.
PROOF Score
Overall: 6.2 / 10 — Conditional. Scored under our PROOF methodology — five checkable pillars, not a vibe.
Should You Buy OnCrawl?
- Request a quote if you're managing an ecommerce catalog, publisher archive, or enterprise site in the hundreds-of-thousands-of-URLs range where crawl budget genuinely limits SEO outcomes.
- Skip it if your site is under roughly 100,000 URLs — Screaming Frog's free or $279/year tier covers the same technical fundamentals for a fraction of the cost.
- Don't compare it on price to a $29/month SEO suite — it's sold to a different buyer through a different process entirely.
- Budget for a contract, not a subscription — expect a sales conversation and a multi-year term, not a monthly checkout.
Frequently Asked Questions
Is OnCrawl worth it for a small blog?
No — its value is specifically at enterprise scale. Smaller sites are far better served by free or lower-cost tools like Screaming Frog's free tier, which covers the same technical fundamentals without the enterprise sales process.
Does OnCrawl replace Google Search Console?
No, it complements it — OnCrawl pulls in GSC data rather than replacing it, adding crawl and log-file context that GSC doesn't provide on its own.
Why won't this review just estimate a price?
Because we couldn't verify one, and guessing at enterprise software pricing produces a number that's more likely to mislead than help — see our SEO tools comparison for the same standard applied to SolarWinds and other quote-only tools elsewhere on this site. If you need a real number, requesting a quote directly is the only reliable path.
How large does a site need to be to justify OnCrawl?
There's no single published threshold, but the practical signal is when Screaming Frog's crawl process becomes genuinely impractical on your own hardware — hundreds of thousands of URLs, not tens of thousands. If you're unsure whether you've crossed that line, you likely haven't yet.
