Lumar (formerly DeepCrawl) vs Screaming Frog · 2026
What's the difference between Lumar (formerly DeepCrawl) and Screaming Frog?
Short answer
Screaming Frog is a desktop crawler that surfaces technical SEO problems—broken links, redirect chains, canonicals, image and page-speed issues—fast and cheaply. Lumar (formerly DeepCrawl) is enterprise cloud crawling with scheduled monitoring, historical trending, and stakeholder dashboards for very large sites.
Vendors update features and pricing often. For the most accurate, up-to-date details, always check Lumar (formerly DeepCrawl)'s site and Screaming Frog's site directly.
Lumar (formerly DeepCrawl) is cloud-based enterprise crawling: scheduled crawls at scale, historical trending, health dashboards, and reporting built for teams who need to show a stakeholder that site health moved. Screaming Frog is a desktop crawler. You run it, it tells you exactly what's broken, and you go fix it.
For most teams doing technical SEO, Screaming Frog is the workhorse. Keyword work gets all the attention while the things that actually break conversion go unwatched: unoptimised images, caching, page load times, redirect chains, broken canonicals, missing alt text. Screaming Frog surfaces that class of problem faster and cheaper than anything else. Lumar earns its price when the site is large enough that a laptop can't hold the crawl and someone senior needs a trend line.

Why is Lumar (formerly DeepCrawl) right for my business?
Lumar is the right pick when the crawl itself is an infrastructure problem. Enterprise sites with millions of URLs need cloud crawling, scheduling, and history—and leadership usually needs a dashboard showing site health over time rather than a spreadsheet of URLs. That reporting layer is what you're paying for.
- The site is large enough that desktop crawling isn't practical.
- You need scheduled monitoring and a trend line, not a point-in-time audit.
- Non-SEO stakeholders need dashboards to see site health move.
Why is Screaming Frog right for my business?
Screaming Frog is the right pick for technical SEO work. Teams over-index on keyword analysis and lose track of image optimization, caching, page load times, and the structural elements that quietly disrupt conversion—this is the tool that finds them. For the price of a single enterprise seat elsewhere, a practitioner can audit a site properly and repeatedly.
- You're doing hands-on technical SEO and want findings now.
- You need image optimization, redirect chains, canonicals, and load-time issues surfaced fast.
- Budget matters and one practitioner does the work.
Which is better, Lumar (formerly DeepCrawl) or Screaming Frog?
Screaming Frog for practitioners doing the technical work—it's the best value in the category and it finds the problems that actually hurt conversion. Lumar when the site is enterprise-scale and continuous monitoring plus reporting is the requirement, not the audit itself.
Frequently asked questions
Is Screaming Frog enough for technical SEO?
For most sites, yes. It surfaces broken links, redirect chains, canonical issues, duplicate titles and metadata, image problems, and load-time signals—the issues that actually affect crawlability and conversion.
When do I outgrow Screaming Frog?
When the crawl no longer fits comfortably in your machine's memory, or when someone needs scheduled monitoring and a trend line rather than an audit you run manually.
Which is cheaper?
Screaming Frog, substantially—it's a low-cost annual license versus enterprise platform pricing. Confirm current pricing with each vendor.
Do I need both?
Some enterprise teams run both: Lumar for continuous monitoring and reporting, Screaming Frog for hands-on investigation when something breaks. Smaller teams rarely need the second bill.
What technical issues get missed most often?
Image weight and format, caching configuration, page load time, redirect chains, and orphaned or non-canonical pages. Keyword work gets the attention; these are what quietly cost conversions.
