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.

SpyFu

  • Entry-level Basic plan caps search results and data exports at 10,000 rows, limiting deep research.
  • API access is only available on the top Team/Agency tier, unlike some competitors that offer it at lower price points.
  • Additional user seats cost an extra $30 per user per month even on paid plans.
  • Weekly rank tracking refresh is less frequent than some competitors offering daily updates.

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.

SpyFu: What does SpyFu cost?

SpyFu has three plans: Basic at $29/month (billed annually) or $39/month, Pro + AI starting around $89/month annually (or $59 for the first month, then $119/month), and Team/Agency at $187/month annually or $249/month.

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.

SpyFu: What's included in the Basic plan?

Basic includes 10,000-row search results and data exports, 1 Live Site tracking project, 5,000 weekly tracked keyword rankings, 10 automated reports, and 1 user seat.

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.

SpyFu: What extra do Pro + AI and Team/Agency add?

Pro + AI adds unlimited search results and exports, 10 tracking projects, 10+ years of historical data, 15,000 weekly rank checks, and 100 reports. Team/Agency adds unlimited projects and reports, 50,000 weekly rank checks, and 5 user seats.
