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.; SISTRIX coverage is deepest in German-speaking Europe and thinner in the United States and Asia, so international teams still need Ahrefs or Semrush alongside it.
  • They diverge on capability: OnCrawl covers Log file analysis, SISTRIX covers Visibility Index.
  • 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.

OnCrawl

  • A large publisher or marketplace diagnosing wasted crawl budget on parameterised or low-value URLsnot SISTRIX
  • A technical SEO team that needs server log data joined to crawl data, not just a crawl report on its ownnot SISTRIX
  • An enterprise site comparing crawl-plus-log platforms against Botify or Lumar before committing to a multi-year contractnot SISTRIX
  • A team wanting custom segmentation of crawl and log data without writing SQL against a raw exportnot SISTRIX

SISTRIX

  • Reporting search visibility to a board in Germany where the Visibility Index is the expected metricnot OnCrawl
  • Comparing a domain against competitors over years, including before you started tracking anythingnot OnCrawl
  • Due diligence on an acquisition target where you need visibility history you did not collect yourselfnot OnCrawl
  • Diagnosing whether a traffic drop coincided with a core update by comparing against the whole measured marketnot 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.

SISTRIX

  • Coverage is deepest in German-speaking Europe and thinner in the United States and Asia, so international teams still need Ahrefs or Semrush alongside it.
  • The Visibility Index is domain-level, so a dramatic chart movement can come entirely from pages that carry no commercial value and requires drilling down before it means anything.
  • The link index is smaller than the market leaders, which matters if backlink discovery rather than visibility measurement is your main use.
  • Modules are priced individually, so a team that needs SEO, links and the Optimizer pays a multiple of the entry price for one module.
  • Documentation, community material and support are German-first, and while English is available the depth of the two is not equal.

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.

SISTRIX: What is the Visibility Index actually measuring?

Rankings for a large fixed keyword set per country, weighted by expected traffic, measured weekly. It is not your keyword list, which is what makes it comparable.

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.

SISTRIX: Can it replace Ahrefs or Semrush?

For German-language visibility reporting and competitor history, yes. For global keyword research and backlink analysis it is a complement rather than a replacement.

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.

SISTRIX: How far back does the data go?

To 2008 for the earliest supported countries, which is longer than any rank tracker can offer on your own keyword list.
