The short version

  • Each has a real cost: Lumar the crawl allowance is measured in URLs per month, so full crawls of a large site exhaust it quickly and teams end up sampling, which is exactly how regressions escape.; 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.
  • They diverge on capability: Lumar covers Site crawler, OnCrawl covers Log file analysis.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Lumar

  • The crawl allowance is measured in URLs per month, so full crawls of a large site exhaust it quickly and teams end up sampling, which is exactly how regressions escape.
  • It provides no keyword, ranking or backlink data, so it is always an addition to the SEO budget rather than a consolidation of it.
  • The pipeline gating that justifies the price needs engineering adoption, and a marketing budget cannot buy that agreement.
  • Log file analysis is not the core strength it is at Botify, so crawl budget diagnosis on very large sites is weaker.
  • The 2022 rebrand from DeepCrawl means much of the community knowledge, tutorials and older documentation is filed under the previous name.

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.

Answered from the vendors’ own pages

Lumar: Is Lumar the same as DeepCrawl?

Yes, the same company and product line, rebranded in 2022. Older tutorials under the DeepCrawl name still broadly apply.

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.

Lumar: Can it really block a deployment?

Yes, through Automation Hub integrated into your CI pipeline. Whether your engineering team accepts that gate is the real question.

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.

Lumar: Does it replace Screaming Frog?

For scheduled monitoring and pipeline testing, yes. For quick ad hoc crawls on a laptop, the desktop crawler remains faster and cheaper.

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.
