Seolyzer vs Sitechecker in 2026: log analysis depth vs an all-in-one agency dashboard
One tool fuses crawl data, server logs, and Google Search Console for teams that already understand Googlebot behavior. The other bundles a crawler, rank tracker, and AI Visibility Tracker into a single subscription built for client reporting.
Seolyzer
Sitechecker- Seolyzer streams real-time server log data and cross-references it against crawl data and Google Search Console; Sitechecker has no log analysis capability at all.
- Sitechecker includes an AI Visibility Tracker that monitors brand references in ChatGPT and Perplexity responses. Seolyzer has no AI search monitoring of any kind.
- Seolyzer has no public pricing and requires a demo request. Sitechecker publishes four tiers starting at $89/month.
- Seolyzer offers full API access to crawl, link, and log data on its Professional and Enterprise tiers. Sitechecker restricts API access to its Enterprise plan only.
- Sitechecker ships white-label client reports on Standard and up. Seolyzer has no white-label or client-branding option visible on its public site.
- Seolyzer is used at enterprise scale by Club Med and ManoMano, with ManoMano pulling millions of internal links through the API. Sitechecker is positioned for small-to-mid agencies and in-house SMB teams.
Seolyzer and Sitechecker both sit in the technical SEO category, but they are built for different jobs. Seolyzer is a log-analysis-first platform: its cross-analysis mode merges site crawl data, real-time server logs, and Google Search Console into one view, which is the kind of diagnostic depth enterprise in-house teams and technical consultants reach for when crawl budget or indexing problems need a real answer, not a guess. Sitechecker is closer to an agency operations tool, combining a website crawler, rank tracker, white-label reporting, and an AI Visibility Tracker in one subscription with published pricing starting at $89 a month. Seolyzer requires a demo before you see a price; Sitechecker puts the price on the page and adds AI search monitoring that Seolyzer does not touch at all. The choice comes down to whether you need to see what Googlebot actually did, or whether you need a clean dashboard you can hand to a client.
The tools at a glance
Seolyzer
Technical SEO data platform combining site crawling, real-time log analysis, and Google Search Console in one interface
Seolyzer is a French technical SEO platform built around three data sources that most tools handle separately: a site crawler, real-time server log analysis, and Google Search Console. Its cross-analysis mode fuses all three into a single view, so you can see not just what your site structure looks like but what Googlebot actually did when it visited, which pages it crawled, which it ignored, and where crawl budget went to URLs that never converted into indexing.
The log analysis module streams Googlebot activity as it happens rather than batching it into a weekly export, which matters most during migrations, crawl budget recoveries, or when pages that look technically fine are still not getting indexed. The API is a serious part of the offering too: ManoMano uses it to pull millions of internal links for their data science team, and that kind of usage signals Seolyzer is built to plug into a larger workflow rather than stand alone as a dashboard.
What you do not get is a price on the website. Every plan routes through a demo request, and the interface itself, while functional, does not have the visual polish of tools built more recently. There is also no white-label option, so if client-facing reporting matters to your business, Seolyzer is not going to cover that on its own.

Sitechecker
SEO command center for agencies managing multiple client sites, with crawling, rank tracking, technical issue detection, and AI visibility tracking from a unified dashboard.
Sitechecker packages a website crawler, keyword rank tracker, Google Search Console dashboard, and change-monitoring alerts into a single subscription aimed at agencies and in-house SMB teams. It skips the enterprise sales process entirely: pricing is published on the site, starting at $89 a month for the Basic tier and scaling to $379 for Premium, with a custom Enterprise option above that.
The AI Visibility Tracker is the feature that separates Sitechecker from a plain crawler-plus-rank-tracker bundle. It monitors how a site is referenced in AI-generated responses from ChatGPT and Perplexity, giving agencies a way to add AI search coverage to client reports without buying a second tool. White-label reporting is available from the Standard tier up, letting agencies replace Sitechecker branding with their own for scheduled client deliverables.
The tradeoff is depth. There is no server log analysis, so you cannot see actual Googlebot crawl behavior the way Seolyzer shows it, and API access is locked to the Enterprise plan, which rules out custom data pipelines for anyone on Basic through Premium. For agencies whose main need is a clean, deliverable-ready dashboard rather than raw crawl diagnostics, that tradeoff is usually the right one.

Considering AI Peekaboo alongside Seolyzer and Sitechecker?
Sitechecker's AI Visibility Tracker gives agencies a basic look at ChatGPT and Perplexity mentions, but it is one module inside a broader crawling and rank-tracking suite, not a dedicated AI search platform. If AI visibility reporting is a growing part of your client work rather than an add-on, AI Peekaboo is built specifically for that: a read and write API on every plan, white-label delivery, and a Looker Studio connector for agencies that need to fold AI search data into existing reporting stacks without a sales call.

SeolyzerSeolyzerSitecheckerSitecheckerSeolyzerSitecheckerSeolyzer and Sitechecker are not really competing for the same buyer. Seolyzer sells diagnostic depth: log analysis and cross-analysis are built for people who already know how to read a server log and want to catch discrepancies between what Googlebot does and what GSC reports. Sitechecker sells operational convenience: a priced subscription that covers crawling, rank tracking, alerts, and now AI visibility in one dashboard your account manager can hand to a client. Buy Seolyzer for the problem you cannot solve without log data. Buy Sitechecker for the reporting workflow you need every week.
Bottom line
Go with Seolyzer if crawl budget, indexing gaps, or Googlebot behavior are active problems on a large site and you are prepared to sit through a demo to get pricing. Go with Sitechecker if you run an agency or SMB in-house function that needs a crawler, rank tracker, and AI Visibility Tracker in one subscription with a price you can see before you sign up. Neither tool replaces the other: Seolyzer will not track your rankings and Sitechecker will not show you what Googlebot actually crawled last night.
Frequently asked questions
Does Seolyzer or Sitechecker track AI search visibility like ChatGPT or Perplexity mentions?
Sitechecker does, through its AI Visibility Tracker, available from the Standard plan at $219/month. Seolyzer has no AI search monitoring at all; it is built entirely around traditional crawl, log, and Google Search Console data.
Which tool is cheaper for a small agency just starting out?
Sitechecker has a lower visible entry point at $89/month for the Basic tier, and you know the price before signing up. Seolyzer requires a demo call for any pricing information, which typically signals a higher, enterprise-oriented cost even at the Starter tier.
Can Sitechecker replace Seolyzer for crawl budget analysis on a large site?
No, not for real Googlebot behavior data. Sitechecker crawls your site and reports technical issues, but it has no server log analysis, so it cannot show you which URLs Googlebot actually visited or how often. Seolyzer's real-time log streaming and cross-analysis mode are built specifically for that diagnostic, which Sitechecker does not attempt.
Does either tool offer API access on a standard plan?
Seolyzer includes API access starting on its Professional tier, giving you programmatic access to crawl, link, and log data. Sitechecker restricts API access to its Enterprise plan only, so Basic, Standard, and Premium subscribers cannot pull data into custom pipelines.
Is Seolyzer overkill for a small business website?
Yes, for most small sites it is overkill. Seolyzer is built around log analysis and cross-referencing crawl data against Googlebot behavior, which is only useful once a site is large enough or complex enough for crawl budget to be a real constraint. Small sites with straightforward architecture rarely need that level of diagnostic depth, and Sitechecker's crawler and rank tracker cover the more common day-to-day needs at a lower cost.
Which tool is better for white-label client reporting?
Sitechecker, without question. White-label reports are built into the Standard tier and above, replacing Sitechecker branding with an agency's own logo and colors for scheduled client delivery. Seolyzer has no white-label or client-branding feature visible on its public site, so agencies that need branded deliverables would have to build that layer themselves on top of Seolyzer's data.
