Detailed Review
On a site with a million URLs, the interesting SEO questions are not about keywords. They are about which pages Googlebot actually crawls, how often, and whether crawl budget is being spent on pages that generate revenue or on faceted navigation nobody wants indexed. OnCrawl exists to answer those.
It is a French platform, based in Bordeaux, that joins its own crawl data with your server logs and whatever business data you feed it.
Logs Plus Crawl
The crawl tells you what exists and how it links together. The logs tell you what search engines actually requested. Joining them reveals orphan pages that get crawled, important pages that do not, and crawl budget being consumed by parameters and pagination.
For large e-commerce and publishing sites, this analysis routinely finds problems worth far more than the subscription — and it is invisible to keyword-oriented tools.
Bringing Your Own Data
OnCrawl ingests analytics, Search Console and business data such as margin, stock level or article age, then segments the site by those dimensions. Being able to say that out-of-stock products consume a third of crawl budget, or that articles older than two years get crawled but earn nothing, turns SEO analysis into an operational argument.
Scale
The platform is built for millions of URLs, with segmentation and comparison across crawls so you can see whether last quarter's work moved the numbers. That is a different engineering problem from crawling a 5,000-page brochure site, and it is where OnCrawl earns its place.
Limitations to Consider
OnCrawl is aimed at large sites — below roughly 50,000 URLs the log analysis rarely justifies the cost, and Screaming Frog will cover the technical audit for GBP 199 a year. Log file access requires cooperation from whoever runs the servers, which is often the hardest part of an implementation. And it has no keyword or backlink research, so it is one component of a stack.
Who Should Use OnCrawl
Technical SEO teams at large e-commerce sites, publishers and marketplaces where crawl budget and indexation are the binding constraints, and who can get access to server logs.

Frequently Asked Questions
Which URLs search engines request, how often and with what response codes. Combined with crawl data it reveals crawl budget waste, orphan pages being crawled and important pages being ignored — none of which is visible from a crawl alone.
No. Below roughly 50,000 URLs the analysis rarely justifies the cost, and Screaming Frog covers technical auditing far more cheaply.
From whoever runs your hosting or CDN. Arranging that access is usually the most time-consuming part of onboarding, so start it early.
No. It is a technical and log analysis platform. You will still want Sistrix, Mangools or similar for keyword and visibility work.
OnCrawl is built as a European alternative to Botify: French enterprise SEO platform that joins crawl data to server logs and analytics, revealing how search engines actually behave on large sites. It will not be a like-for-like feature match in every respect, so check the review above for where the two genuinely differ before switching.
