Lumar vs Screaming Frog SEO Spider in 2026: enterprise five-module platform vs the £199 desktop standard
Lumar bundles AI visibility, accessibility, and site speed monitoring into an enterprise crawl platform sold through a demo. Screaming Frog is the desktop crawler most technical SEOs already have installed, unlimited URLs for £199 a year with server log analysis built in.
Lumar
Screaming Frog SEO Spider- Screaming Frog includes server log analysis in its standard £199/year license. Most competitors, including Lumar, do not publicly detail whether log analysis is part of their platform.
- Lumar tracks brand visibility across ChatGPT, Gemini, and Perplexity as part of its platform. Screaming Frog has no AI brand-visibility tracking of any kind.
- Screaming Frog's paid license has no URL limit for £199 a year. Lumar has no public pricing at all; every deal starts with a sales demo.
- Screaming Frog runs locally on your own machine with no cloud dependency, while Lumar is a hosted enterprise platform built for team-wide reporting.
- Lumar is the only one of the two with WCAG 2.2 accessibility compliance testing built into the crawl workflow.
- Screaming Frog supports custom extraction via XPath, CSS, and regex, letting users pull arbitrary data points like prices or review counts straight from page source.
- Screaming Frog connects directly to Google Analytics, Search Console, and PageSpeed Insights to overlay traffic data on crawl results. Lumar does not publicly detail equivalent Google integrations.
Lumar and Screaming Frog SEO Spider both start from the same place, a crawl of your site, and go in almost opposite directions from there. Lumar folds the crawl into a five-part enterprise platform: AI brand visibility tracking across ChatGPT, Gemini, and Perplexity, WCAG 2.2 accessibility testing, Core Web Vitals monitoring, and AI-generated remediation code, sold with no public price and a mandatory demo. Screaming Frog does one thing, crawling, and does it with more raw diagnostic depth than most paid tools, including server log analysis in the standard £199/year license with no URL cap. If your organization needs AI visibility and accessibility compliance reported alongside crawl data, Lumar is built for that. If you need to open a tool and start crawling a client site in the next ten minutes, Screaming Frog is still the one nearly everyone reaches for first.
The tools at a glance
Lumar
Enterprise website optimization combining technical SEO, AI visibility, and accessibility
Lumar (formerly DeepCrawl) treats crawling as one of five connected modules rather than the whole product. Alongside the standard technical SEO checklist, redirects, canonicals, hreflang, structured data, internal linking, it runs an AI-powered prioritization layer that scores issues by likely impact, a GEO/AEO module tracking brand visibility across ChatGPT, Gemini, and Perplexity, Core Web Vitals monitoring, and WCAG 2.2 accessibility testing under one contract.
That consolidation is the pitch: instead of a crawler, an accessibility auditor, a speed monitor, and an AI visibility tracker as four separate line items, an enterprise team gets one vendor, one login, and one report that covers all four. For legal and compliance stakeholders who need accessibility findings in the same document as SEO findings, that alone can justify the switch.
The cost of that breadth is access. There is no published price and no way to sign up without a sales conversation, and the platform is built assuming a team with dedicated technical SEO staff to configure it. For a solo consultant who just needs to crawl a client site this week, that process is the wrong shape entirely.

Screaming Frog SEO Spider
The industry-standard desktop crawler for technical SEO audits
Screaming Frog SEO Spider has been the default crawler for technical SEO work since 2010, and the reason is straightforward: it runs on your own machine, has no URL cap on the paid license, and covers redirects, canonicals, hreflang, structured data, and heading structure with a depth that few cloud tools match, let alone beat, at £199 a year.
Server log analysis is bundled into the standard license rather than sold as an add-on, which is unusual: upload your access logs and the Spider maps exactly which URLs Googlebot is hitting, how often, and where crawl budget is being wasted. Google Analytics, Search Console, and PageSpeed Insights connect directly, so you can see which broken or thin pages are actually pulling traffic before you decide what to prioritize.
What it will not do is give you a shared cloud dashboard, scheduled recurring crawls out of the box, or anything resembling AI visibility tracking. The interface also assumes you already know what you are looking at, filters and raw data over guided workflows, so newcomers face a real learning curve before the tool starts paying for itself.

Considering AI Peekaboo alongside Lumar and Screaming Frog SEO Spider?
Lumar bundles AI brand visibility tracking for ChatGPT, Gemini, and Perplexity into its enterprise platform, but only as one module inside a five-part contract gated behind a demo. Screaming Frog has no AI visibility tracking at all, it stays entirely inside crawl and log data. If AI answer-engine visibility is the actual gap in your stack rather than a bundled extra, AI Peekaboo ships a dedicated read and write API on every plan from $50 a month, tracks five named AI surfaces, and includes white-label delivery without a sales call, worth evaluating alongside either crawler.

LumarScreaming Frog SEO SpiderScreaming Frog SEO SpiderLumarLumarScreaming Frog SEO SpiderScreaming Frog SEO SpiderThe honest comparison here is not feature-for-feature, it is process versus price. Lumar sells consolidation: one vendor covering crawling, AI visibility, accessibility, and speed, at a cost and sales cycle that only makes sense once an organization is large enough to need all four. Screaming Frog sells raw capability at a price that barely registers as a line item, £199 a year for unlimited crawling and server log analysis that some competitors charge extra for or omit entirely. Most technical SEOs end up with Screaming Frog on their laptop regardless of what enterprise platform their company also pays for, because sometimes you just need to crawl a site right now.
Bottom line
Book the Lumar demo if your organization needs AI visibility tracking and WCAG 2.2 accessibility compliance reported alongside crawl data, and has the budget and staff for an enterprise vendor relationship. Buy the Screaming Frog license if you need a crawler you can be using in the next ten minutes, £199 a year with no URL cap and server log analysis included is difficult to argue with at any budget. For most agencies and in-house teams, Screaming Frog is the default tool on the desktop either way, with Lumar layered on top only once AI visibility and accessibility reporting become genuine organizational requirements.
Frequently asked questions
Is Screaming Frog SEO Spider a real substitute for Lumar?
For pure crawling, yes, Screaming Frog matches or exceeds Lumar's crawl depth for a fraction of the price. What it does not replace is Lumar's AI brand visibility tracking and WCAG 2.2 accessibility testing, so a team that specifically needs either of those under one platform will still need to look at Lumar or pair Screaming Frog with separate accessibility and AI visibility tools.
Does Screaming Frog track AI search visibility the way Lumar does?
No, Screaming Frog has no AI brand visibility or GEO/AEO tracking feature of any kind. It stays entirely within traditional crawl and log data, redirects, canonicals, structured data, and Googlebot behavior, which is a different problem from monitoring how a brand appears in ChatGPT or Gemini answers.
Why does Lumar not publish pricing while Screaming Frog does?
Lumar sells as a custom-configured enterprise platform across five modules, which typically means negotiated per-contract pricing rather than a published price list. Screaming Frog sells as a fixed-tier desktop product, so its full price ladder, free up to 500 URLs, £199 a year for a single unlimited license, down to £169 per license at 20-plus seats, is visible without talking to sales.
Can Screaming Frog analyze server logs, or do I need a separate tool for that?
Screaming Frog includes server log analysis in its standard license at no extra cost. Upload Apache, Nginx, or IIS logs and it maps Googlebot crawl frequency against your site structure, which is one of its most underused features and a genuine differentiator against tools that charge separately for log analysis or skip it entirely.
Does either tool handle WCAG accessibility compliance testing?
Only Lumar does. WCAG 2.2 accessibility testing is built into Lumar's crawl workflow as one of its core modules, which matters for enterprise teams with legal compliance obligations. Screaming Frog has no accessibility testing feature, so agencies that need it should pair Screaming Frog with a dedicated accessibility tool.
Is Screaming Frog cloud-based or does it need to run on my computer?
Screaming Frog runs as a desktop application on Windows, macOS, and Linux, with crawls executing locally on your own hardware rather than in the cloud. That means no collaborative team dashboards out of the box, but it also means your crawl data never leaves your machine unless you choose to export it, which some agencies prefer for client confidentiality.
