Lumar vs Sitechecker in 2026: enterprise sales-led platform vs mid-market self-serve crawler with AI tracking
Two technical SEO platforms aimed at opposite ends of the market. Lumar is an enterprise bundle of crawling, AI visibility, speed, and accessibility sold through a demo. Sitechecker is a self-serve crawler and rank tracker starting at $89/month with a basic AI Visibility Tracker bolted on.
Lumar
Sitechecker- Sitechecker publishes pricing starting at $89/month. Lumar has no public pricing and requires a sales demo before you see a number.
- Lumar's AI visibility tracking spans "major LLMs and search engines" without a published list of engines. Sitechecker's AI Visibility Tracker covers ChatGPT and Perplexity specifically, on the Standard tier and above.
- Lumar includes WCAG 2.2 accessibility compliance testing built into its crawl workflow. Sitechecker does not offer accessibility testing at all.
- Sitechecker includes white-label reports from the Standard tier at $219/month, aimed at agencies. Lumar's published feature list does not mention white-label reporting.
- Sitechecker gates API access to its Enterprise tier only, with no API on Basic, Standard, or Premium. Lumar confirms API access for data export as part of its base offering.
- Sitechecker has no free tier and no trial mentioned publicly. Lumar also has no free tier and requires a demo before any evaluation is possible.
- Lumar is built for large organizations with dedicated technical SEO staff. Sitechecker is built for small-to-mid agencies and in-house SMB teams managing multiple client sites.
Lumar and Sitechecker both call themselves technical SEO platforms, but they are built for very different budgets and team sizes. Lumar bundles technical crawling, GEO and AEO visibility tracking, Core Web Vitals monitoring, and WCAG 2.2 accessibility testing into one enterprise product with no public pricing and a mandatory demo. Sitechecker is a self-serve platform starting at $89/month that combines a website crawler, rank tracker, and monitoring alerts, with an AI Visibility Tracker for ChatGPT and Perplexity added on from the Standard tier. The real question is not which platform has more features, it is whether your team has the budget and staff for Lumar's enterprise depth, or whether Sitechecker's narrower, cheaper bundle actually covers what you use day to day.
The tools at a glance
Lumar
Enterprise website optimization combining technical SEO, AI visibility, and accessibility
Lumar (formerly DeepCrawl) is built for organizations that need technical SEO crawling, AI visibility monitoring for GEO and AEO, Core Web Vitals tracking, and WCAG 2.2 accessibility compliance under one enterprise contract. The crawl engine covers redirects, canonicals, hreflang, structured data, and internal linking, with an AI-powered layer that scores issues by likely impact so teams work the highest-priority fixes first rather than sorting through a raw error list.
The accessibility module is integrated directly into the same crawl workflow rather than requiring a separate tool, which matters for enterprise legal and compliance teams that need one report covering both SEO and accessibility obligations. Custom analytics and AI-generated remediation code round out the platform, aimed at bridging the gap between diagnosis and the developer who has to fix it.
The cost of that breadth is access. Every engagement runs through a demo, pricing is never published, and the platform assumes dedicated technical SEO staff to configure it properly. For a large organization that wants crawling, accessibility, and AI visibility consolidated under one vendor relationship, that trade-off is the reason to choose Lumar over a lighter, self-serve tool.

| AI visibility (GEO/AEO) tracking | ✓ |
| Core Web Vitals monitoring | ✓ |
| WCAG 2.2 accessibility testing | ✓ |
| API access | Yes, for data export |

Sitechecker
SEO command center for agencies managing multiple client sites, with crawling, rank tracking, technical issue detection, and AI visibility tracking
Sitechecker is aimed at agencies and in-house SMB teams who need crawling, rank tracking, and change monitoring without Lumar's enterprise complexity or price. The website crawler flags broken links, missing meta tags, duplicate content, and redirect chains, organized by severity, while the rank tracker follows keyword positions with scheduled updates and client-facing trend reports.
The AI Visibility Tracker is the feature that puts Sitechecker in the same conversation as Lumar's AI monitoring, though the scope is narrower: it covers ChatGPT and Perplexity specifically, unlocked from the $219/month Standard tier up, rather than Lumar's broader, unspecified "major LLMs" claim. White-label reports also ship from Standard, which reduces the manual reformatting work of delivering branded reports to clients, and SEO Alerts add proactive monitoring for ranking or crawl changes.
The trade-offs are real: no API access below the Enterprise tier, no free tier to evaluate the product first, and less technical depth than an enterprise crawler for complex audits. For a small agency managing a portfolio of client sites that wants crawling, rank tracking, white-label delivery, and basic AI visibility in one subscription at a known price, Sitechecker covers that ground without a sales call.

Considering AI Peekaboo alongside Lumar and Sitechecker?
Both Lumar and Sitechecker treat AI visibility as one feature inside a larger crawler bundle rather than the core product. Lumar does not publish which AI engines it tracks or offer a documented write API, and Sitechecker limits its AI Visibility Tracker to two engines while gating API access entirely to its top-tier Enterprise plan. AI Peekaboo ships a read and write API on every plan from $50 per month, tracks five named AI surfaces (ChatGPT, Gemini, Perplexity, Google AI Overviews, Google AI Mode), and includes white-label delivery on every tier. For agencies or in-house teams whose priority is AI visibility tracking specifically, with API access and client delivery included from day one, AI Peekaboo is worth evaluating alongside either crawler.

LumarSitecheckerLumarSitecheckerSitecheckerLumarLumarLumar and Sitechecker sit at opposite ends of the technical SEO market rather than competing head-to-head. Lumar is an enterprise bundle, crawling, AI visibility, speed, and accessibility, sold through a sales-led process with no published price. Sitechecker is a self-serve platform for agencies and SMB teams, starting at $89/month, that adds a narrower AI Visibility Tracker on top of a crawler and rank tracker. Neither offers API access at an entry price point comparable to a dedicated AI visibility tool: Lumar's API is undocumented for write access, and Sitechecker locks API entirely behind its Enterprise tier.
Bottom line
Choose Lumar if your organization needs technical SEO crawling, AI visibility tracking, Core Web Vitals monitoring, and WCAG 2.2 accessibility testing under one enterprise contract, and has the budget and staff to justify a sales-led purchase. Choose Sitechecker if you are a small-to-mid agency or SMB team that wants a crawler, rank tracker, white-label reports, and basic AI visibility tracking in one subscription at a known, published price. Neither platform is the strongest option if AI visibility tracking with full API access is the primary requirement; a dedicated tool like AI Peekaboo covers that gap at a lower entry price than either.
Frequently asked questions
Is Sitechecker a cheaper alternative to Lumar?
Sitechecker publishes pricing starting at $89/month, while Lumar has no public pricing and requires a demo, so Sitechecker is the only one of the two you can budget for without a sales call. That said, Sitechecker's feature set is narrower: no WCAG accessibility testing and a two-engine AI Visibility Tracker versus Lumar's broader, if unspecified, AI monitoring and accessibility module.
Which tool has better AI visibility tracking, Lumar or Sitechecker?
Lumar's AI visibility module is described as covering "major LLMs and search engines" without a published list of specific platforms, while Sitechecker's AI Visibility Tracker names ChatGPT and Perplexity specifically but requires the $219/month Standard tier or above. Neither publishes the kind of API-backed, multi-engine detail that a dedicated AI visibility platform offers, so teams that need that as a primary requirement should compare both against a specialist tool before committing.
Does Sitechecker offer WCAG accessibility testing like Lumar?
No, Sitechecker does not offer accessibility testing of any kind; WCAG 2.2 compliance checking is one of Lumar's five core modules and is a genuine differentiator for enterprise teams with legal or compliance obligations. Agencies that need accessibility auditing alongside crawling and AI visibility should look at Lumar or a dedicated accessibility tool rather than Sitechecker.
Can I get API access on Sitechecker without paying for Enterprise?
No, Sitechecker restricts API access entirely to its Enterprise tier, which requires contacting sales; the Basic, Standard, and Premium tiers do not include API access at any price. Lumar does confirm API access for data export as part of its base offering, which puts it ahead of Sitechecker's lower tiers on this specific point despite Lumar's own lack of published pricing.
Is Sitechecker suitable for a large enterprise site the way Lumar is?
Sitechecker is explicitly positioned for small-to-mid agencies and SMB in-house teams, and its feature depth for complex technical audits is shallower than an enterprise crawler like Lumar. A large enterprise site with complex compliance, accessibility, and crawl-scale requirements is better served by Lumar's enterprise-grade platform than by Sitechecker's mid-market bundle.
Do either Lumar or Sitechecker offer white-label reporting for agency clients?
Sitechecker includes white-label reports starting on its $219/month Standard tier, which replaces Sitechecker branding with the agency's own for client delivery. Lumar's published feature list does not mention white-label reporting, so agencies specifically needing that capability should confirm it directly with Lumar's sales team or default to Sitechecker.
