Pick
Lumar
Pick Lumar if you want the better-funded company ($37.6M); and SOC 2 Type 2 matters for your security review.
Head-to-head review · Updated June 2026
Lumar vs OnCrawl: which one wins in 2026?
Lumar and OnCrawl 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 is the more-funded incumbent; OnCrawl is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
OnCrawl
Pick OnCrawl if you trust traction signals — they list 10 customers, Lumar lists 7.
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 OnCrawl
Founded by Francois Goube, Tanguy Moal, based in Bordeaux, France. On their site they list 10 named customers including Adidas, L'Oreal, Ticketmaster, Harrods.
Enterprise SEO data platform combining crawl, logs, and AI insights.
What people praise
- JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
- Log file analyzer processes 500M+ log lines per day, surfacing how Googlebot, Bingbot, and AI crawlers actually behave on the site.
- Cross-references crawl data, server logs, GSC, GA4, Adobe Analytics, and Majestic backlinks in one analysis - few competitors integrate all five sources.
- 100% unsampled data analysis appeals to enterprise SEOs frustrated with GA4 sampling and Search Console limits.
Where it falls short
- No public pricing - book-a-demo gating means SMBs and indie consultants are filtered out before evaluation.
- Capterra rating of 3.8 is the lowest among major technical SEO crawlers, with reviewers citing UI complexity and pricing opacity.
- Steep learning curve - the platform assumes data-science fluency, which leaves marketers needing a technical SEO specialist to extract value.
- Self-serve onboarding is limited; complex multi-source setups (logs plus crawl plus analytics) typically need OnCrawl's customer success team.

Reasons to pick one over the other
Reasons to pick Lumar over OnCrawl
- Public pricing. Lumar publishes 1 tiers on its website; OnCrawl requires a sales conversation.
- Better-funded incumbent. Lumar has raised $37.6M, giving it more runway and shipping velocity than OnCrawl.
- SOC 2 Type 2. Lumar carries SOC 2 Type 2; OnCrawl does not yet, which can hold up procurement.
- More verified reviews. Lumar has 101 G2 reviews vs OnCrawl's none on file, so the average rating carries more weight.
- What users praise most. Handles very large sites (millions of URLs) where desktop crawlers like Screaming Frog hit resource limits
Reasons to pick OnCrawl over Lumar
- More named customers. OnCrawl lists 10 customers vs Lumar's 7, including Adidas, L'Oreal, Ticketmaster.
- What users praise most. JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
Switching from one to the other
From Lumar to OnCrawl
Export your saved queries and prompt panels from Lumar (most tools support CSV export). Most OnCrawl setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate OnCrawl'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 OnCrawl to Lumar
Same flow in reverse. Export from OnCrawl, 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.

A third option
Both Lumar and OnCrawlare 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 OnCrawl?
Honestly: neither one fully solves the problem. Lumar and OnCrawl 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 OnCrawl cost?
Lumar starts at Custom. OnCrawl starts at Custom. 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 OnCrawl actually improve your AI visibility, or just measure it?
Both Lumar and OnCrawl 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 OnCrawl?
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.
