DebugBear vs Seolyzer in 2026: performance monitoring vs real-time log analysis and crawl budget diagnostics
One tracks real-user performance, synthetic tests, and Lighthouse scores from a published price around $68 a month. The other fuses crawl data, real-time server logs, and Google Search Console, but only after a demo call.
DebugBear
Seolyzer- DebugBear publishes self-serve pricing from roughly $68 a month. Seolyzer has no public pricing at all; every plan requires a demo request.
- Seolyzer streams real-time server log data to show actual Googlebot crawl behavior. DebugBear has no log analysis capability of any kind.
- DebugBear tracks Core Web Vitals and Lighthouse scores as its core function. Seolyzer does not track Core Web Vitals or Lighthouse scores; it is focused on crawl, indexing, and log data instead.
- DebugBear offers white-label exports and Looker Studio integration on paid plans. Seolyzer has no white-label or client-sharing features visible from its public site.
- Seolyzer's cross-analysis mode fuses crawl data, log files, and Google Search Console into one view, a capability DebugBear does not have or attempt.
- Neither tool tracks AI search visibility, AI Overviews citations, or LLM answer engine mentions; both are focused entirely on traditional performance or crawl health.
- Seolyzer is GDPR compliant with European data hosting, a point it states explicitly. DebugBear does not make an equivalent claim in its public materials.
DebugBear and Seolyzer both sit under the technical SEO umbrella, but they solve almost entirely different problems and rarely compete for the same budget line. DebugBear is a performance monitoring platform: real-user data, synthetic testing, and Lighthouse score tracking, combined so a site-speed regression and its cause show up on the same timeline. Seolyzer is a crawl-budget and indexing diagnostics platform: it streams real-time Googlebot activity from your server logs and cross-references it against crawl data and Google Search Console to show what Googlebot actually did, not just what your site structure looks like. Neither tool touches the other's core job. DebugBear has no log analysis or crawl-budget diagnostics, and Seolyzer does not track Core Web Vitals or Lighthouse scores at all. The choice mostly comes down to which problem you actually have: is it site speed, or is it pages not getting crawled and indexed the way they should be.
The tools at a glance
DebugBear
Web performance monitoring that combines real-user data, synthetic testing, and Lighthouse score tracking to catch regressions before they affect rankings.
DebugBear brings together three performance data sources that are usually spread across separate tools: real-user monitoring segmented by page, device, and country; synthetic monitoring that runs scheduled tests from controlled environments for reliable regression detection; and Lighthouse score tracking that shows exactly which audit failure caused a score to drop and when. All three sit on the same timeline.
Every paid plan includes unlimited domains, which suits agencies managing many client sites, and the Looker Studio connector turns the data into client-facing dashboards without custom development. Pricing is published and self-serve, starting around $68 a month, with API access available even on the entry tier in limited form.
DebugBear has no crawling, no log file analysis, and no Google Search Console integration. If the problem you are diagnosing is why pages are not being indexed or where crawl budget is being wasted, DebugBear was not built to answer that; it answers whether pages are fast, not whether Googlebot is finding and indexing them properly.

Seolyzer
Technical SEO data platform combining site crawling, real-time log analysis, and Google Search Console in one interface
Seolyzer is built around three data sources: a site crawler, real-time server log analysis, and Google Search Console. Its cross-analysis mode fuses all three into one view, surfacing pages that are crawled but not indexed, pages GSC shows impressions for that Googlebot rarely visits, and other discrepancies that only become visible when the sources are compared directly rather than reviewed one at a time.
The log analysis module streams Googlebot activity in real time rather than batch-processing logs weekly, which matters for large sites going through migrations or crawl-budget recovery where waiting days for a report costs time. The API pulls crawl data, internal link maps, and log results into external workflows, and ManoMano reportedly uses it to extract millions of internal links for data science work, a sign the platform is built to plug into larger systems, not just serve as a standalone dashboard.
Seolyzer has no published pricing, no free tier, and no self-serve signup, only a demo request. There is also no white-label or client-sharing feature visible on its public site, and it requires real familiarity with server log formats and Googlebot behavior to get full value, which makes it a poor starting point for teams new to log analysis.

Which should you choose?
DebugBearSeolyzerDebugBearSeolyzerDebugBearSeolyzerDebugBearThis is less a head-to-head and more two specialists that happen to share a category page. DebugBear answers "is this page fast, and did it just get slower." Seolyzer answers "is Googlebot actually crawling and indexing the pages I think it is, and where is crawl budget going." A site can have excellent Core Web Vitals scores in DebugBear and still be leaking crawl budget on faceted navigation URLs that Seolyzer would catch, and the reverse is just as true. Neither platform substitutes for the other, so the real decision is which failure mode you are currently diagnosing.
Bottom line
Pick DebugBear if your open question is about site speed, Core Web Vitals regressions, or the gap between lab and real-user performance, and you want to start today at a published price. Pick Seolyzer if you are managing a large site with crawl budget or indexing problems and need real-time Googlebot behavior fused with crawl and Search Console data, and you are prepared to go through a demo to get pricing. Large enterprise sites often need both eventually; they are not a choice between equals so much as a choice between two different diagnoses.
Frequently asked questions
Do DebugBear and Seolyzer actually compete with each other?
Not directly. DebugBear is a performance monitoring platform built around real-user data, synthetic testing, and Lighthouse scores, while Seolyzer is a crawl and log analysis platform built around Googlebot behavior and indexing diagnostics. They share the technical SEO category but solve different problems, and many large sites would plausibly use both rather than choosing one over the other.
Does Seolyzer track Core Web Vitals like DebugBear does?
No. Seolyzer's public materials do not describe Core Web Vitals or Lighthouse score tracking anywhere in its feature set. It focuses on site crawling, real-time server log analysis, and Google Search Console data. For Core Web Vitals monitoring specifically, DebugBear is the tool built for that job.
Why does Seolyzer require a demo instead of publishing pricing?
Seolyzer sells through a demo request rather than self-serve signup, which is typical for tools positioned at enterprise clients with large, custom-scoped sites, such as its stated Club Med and ManoMano customers. There is no free tier or trial listed publicly, so cost cannot be evaluated without booking that call, unlike DebugBear's published tiers.
Is Seolyzer harder to use than DebugBear?
For most teams, yes. Seolyzer's real-time log analysis assumes familiarity with server log formats and Googlebot crawl behavior, which is a specialist skill set. DebugBear's performance dashboards are more approachable for teams without that background, since Core Web Vitals and Lighthouse scores are more widely understood concepts among SEOs and marketers.
Does either tool track AI search visibility or AI Overviews?
No, neither does. Seolyzer explicitly states it has no AI search visibility tracking and focuses entirely on traditional crawl and indexing health, and DebugBear's feature set is limited to performance monitoring with no AI-answer-engine coverage either. Teams needing that would need a separate, dedicated AI visibility tool.
Can Seolyzer be used for agency client reporting the way DebugBear can?
Not as easily. DebugBear offers white-label exports and a Looker Studio connector on its Pro and Enterprise plans specifically for client-facing reporting. Seolyzer has no white-label or client-sharing feature visible on its public site, which makes it better suited to internal or consultant-led diagnostic work than polished client deliverables.
