The short version

  • Each has a real cost: OnCrawl no pricing is published anywhere on the site, so early-stage comparison against Botify or Lumar requires getting quotes from all three before any evaluation can start.; seoClarity the cost simply moves to data, so keyword and crawl limits become the negotiation and overages are agreed case by case rather than published.
  • They diverge on capability: OnCrawl covers Log file analysis, seoClarity covers Research Grid.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A team wanting custom segmentation of crawl and log data without writing SQL against a raw exportnot seoClarity

  • A large organisation that wants regional teams and writers to have direct access rather than exported reportsnot OnCrawl
  • Tracking very large keyword sets daily across countries and devices in one systemnot OnCrawl
  • Giving content teams optimisation briefs from the same ranking data the SEO team reports onnot OnCrawl
  • Replacing several per-seat subscriptions where licence count rather than data volume was the cost drivernot OnCrawl

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OnCrawl

  • No pricing is published anywhere on the site, so early-stage comparison against Botify or Lumar requires getting quotes from all three before any evaluation can start.
  • Log file analysis requires the customer to actually supply raw server logs, which many marketing teams cannot get from their infrastructure team without a separate internal project.
  • It is a smaller company than Botify, so enterprise buyers evaluating vendor stability and roadmap longevity weigh that against the lower likely price.
  • The interface and terminology assume a working knowledge of crawl budget and log analysis concepts, so it is a poor fit for a generalist marketer without technical SEO background.
  • Data retention periods are tied to plan tier, so historical trend analysis beyond the contracted retention window is not available without upgrading before the data would otherwise be purged.

seoClarity

  • The cost simply moves to data, so keyword and crawl limits become the negotiation and overages are agreed case by case rather than published.
  • The interface is dense and built for daily practitioners, so the unlimited-user policy only pays off if you also fund training for the casual users you invite.
  • Onboarding is guided and slow by design, and teams expecting to self-serve within a week are usually disappointed.
  • Backlink data is licensed from third parties, so link analysis is a weaker reason to choose it than crawling or rank tracking.
  • Content optimisation scoring is shallower than dedicated content tools, and teams serious about editorial briefs often keep a separate subscription.

Answered from the vendors’ own pages

OnCrawl: Do I need to provide my own server logs?

Yes, log file analysis is only available if you can export raw access logs from your web server or CDN; without them OnCrawl functions as a crawler only.

seoClarity: Is unlimited users genuinely unlimited?

Yes, seats are not a pricing lever. Keywords tracked, pages crawled and data retention are the levers instead.

OnCrawl: How much does OnCrawl cost?

It is not published. Pricing is quoted based on crawl volume, log volume and retention period; get a quote before comparing it to Botify or Lumar.

seoClarity: How does it compare on keyword data?

Research Grid is competitive at enterprise scale, but for ad hoc keyword research many teams still prefer Ahrefs or Semrush interfaces.

OnCrawl: Is this suitable for a small business site?

Generally not economically; the log analysis capability that justifies the cost only pays off once a site is large enough that Google is not crawling every page anyway.

seoClarity: What is the real cost driver?

Tracked keyword volume across markets and devices. Model that first, because it determines the quote more than anything on the feature list.
