Head-to-head review · Updated June 2026

Lumar vs Screaming Frog: which one wins in 2026?

Lumar and Screaming Frog both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Lumar has raised $37.6M, Screaming Frog has raised Bootstrapped; Lumar is the more-funded incumbent; Screaming Frog is the leaner challenger.

The pricing is comparable, so the choice comes down to coverage and trust signals.

The verdict
★ Our pick
Pick

Lumar

Pick Lumar if you trust traction signals — they list 7 customers, Screaming Frog lists 0; and you want the better-funded company ($37.6M); and SOC 2 Type 2 matters for your security review.

Pick

Screaming Frog

Screaming Frog is the right pick if your team prefers their approach and pricing fits.

If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.

The case for Lumar

Lumar has raised $37.6M (Series B (Aug 2022)). Founded by Michal Magdziarz, Matt Jones, based in London, UK. On their site they list 7 named customers including Adobe, Deloitte, Motley Fool, Comcast. Pricing starts at Custom.

Enterprise website intelligence platform (formerly DeepCrawl).

What people praise

  • Handles very large sites (millions of URLs) where desktop crawlers like Screaming Frog hit resource limits
  • Renders JavaScript pages to capture client-side content, critical for modern stacks
  • Protect app runs SEO QA in CI/CD pipelines to catch noindex or blocked resource regressions before launch
  • Visual dashboards are clearer than Excel exports from competing crawlers and prioritize fixes by impact

Where it falls short

  • Pricing is entirely custom, no public tiers, and reviewers consistently call it expensive vs competitors
  • Steep learning curve, the UI is described as overwhelming and very technical for non-SEO users
  • No competitor data inside the product, you cannot benchmark against rival domains
  • Crawls can be slow on very large sites because of the depth of analysis

The case for Screaming Frog

Screaming Frog has raised Bootstrapped. Founded by Dan Sharp, based in Henley-in-Arden, UK. Pricing starts at $0/mo.

Desktop SEO crawler used by technical SEOs everywhere.

What people praise

  • Free version actually works for sites under 500 URLs, which reviewers say is rare in SEO tooling.
  • Comprehensive technical audit catches broken links, redirect chains, duplicate content, missing canonicals, and metadata errors in one pass.
  • Custom extraction with XPath and CSS selectors is repeatedly cited as the killer feature for scraping data no other crawler can pull.
  • Recent integrations with OpenAI, Claude, and Gemini let users run prompts against scraped content during a crawl.

Where it falls short

  • Desktop-only Java app, so reviewers complain there is no cloud dashboard and no way to share live crawl data with teammates.
  • Heavy memory footprint, with users reporting that large sites (1M+ URLs) require 32GB RAM and database storage mode.
  • UI looks dated and the learning curve is steep for non-technical users, especially around XPath extraction.
  • No keyword research, backlink analysis, or rank tracking, so users still need a second tool for those workflows.

Feature parity

What each one ships that the other doesn't. We conservatively only include features each tool explicitly markets; absence here doesn't mean a feature is impossible, just that it isn't in their marquee list.

When each one wins

When Lumar wins
  • You're enterprise and need to call a reference. Lumar lists 7 named customers; Screaming Frog lists 0.
  • You want the better-funded incumbent. Lumar has raised $37.6M, giving it more runway and shipping velocity.
  • Procurement requires SOC 2 Type 2. Lumar has it; Screaming Frog doesn't yet.
When Screaming Frog wins
  • Budget is the constraint. Screaming Frog starts at $0/mo vs Lumar's $∞/mo, so on a per-seat basis it's the cheaper way in.
  • Free version actually works for sites under 500 URLs, which reviewers say is rare in SEO tooling.
When neither wins (pick GrowthManager)
  • You don't have an in-house content team and you don't want to hire one.
  • You want one $999/mo invoice instead of stacking Lumar plus an agency.
  • You need the team that measures to also act on the data, in the same week.
  • You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.

Reasons to pick one over the other

Reasons to pick Lumar over Screaming Frog

  1. Better-funded incumbent. Lumar has raised $37.6M, giving it more runway and shipping velocity than Screaming Frog (Bootstrapped).
  2. More named customers. Lumar lists 7 customers vs Screaming Frog's 0, including Adobe, Deloitte, Motley Fool.
  3. SOC 2 Type 2. Lumar carries SOC 2 Type 2; Screaming Frog does not yet, which can hold up procurement.
  4. What users praise most. Handles very large sites (millions of URLs) where desktop crawlers like Screaming Frog hit resource limits

Reasons to pick Screaming Frog over Lumar

  1. Lower entry price. Screaming Frog publishes a clear entry tier at $0/mo; Lumar gates pricing.
  2. More plan flexibility. Screaming Frog offers 4 pricing tiers vs Lumar's 1, so there's a better chance one fits your team size.
  3. More verified reviews. Screaming Frog has 186 G2 reviews vs Lumar's 101, so the average rating carries more weight.
  4. What users praise most. Free version actually works for sites under 500 URLs, which reviewers say is rare in SEO tooling.

Switching from one to the other

From Lumar to Screaming Frog

Export your saved queries and prompt panels from Lumar (most tools support CSV export). Most Screaming Frog setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Screaming Frog's data againstLumar's; one to two weeks of full reconciliation before you cancel Lumar. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Screaming Frog to Lumar

Same flow in reverse. Export from Screaming Frog, import to Lumar. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.

From either to GrowthManager.ai

We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

Screaming Frogwhat users complain about

  • Desktop-only Java app, so reviewers complain there is no cloud dashboard and no way to share live crawl data with teammates.
  • Heavy memory footprint, with users reporting that large sites (1M+ URLs) require 32GB RAM and database storage mode.
  • UI looks dated and the learning curve is steep for non-technical users, especially around XPath extraction.

A third option

Both Lumar and Screaming Frogare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions

Which is better, Lumar or Screaming Frog?

Honestly: neither one fully solves the problem. Lumar and Screaming Frog are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick Lumar for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.

How much do Lumar and Screaming Frog cost?

Lumar starts at Custom. Screaming Frog starts at $0/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.

Do Lumar and Screaming Frog actually improve your AI visibility, or just measure it?

Both Lumar and Screaming Frog are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.

What's the GrowthManager.ai alternative to Lumar and Screaming Frog?

GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
