Lumar: what it does, what it costs
The enterprise crawler formerly called DeepCrawl, now covering accessibility too.

What Lumar is
Lumar is the platform that was DeepCrawl until it rebranded, and it remains squarely enterprise: very large crawls, scheduled monitoring, health scores designed to be shown to people who do not do SEO, and issue classification aimed at getting engineering teams to act. If you have heard the name DeepCrawl, this is the same product with a wider remit.
That wider remit is the interesting part. Alongside technical SEO it now audits accessibility, and its own customer testimonials lead with that — which makes sense for the organisations it sells to, where accessibility is a compliance obligation rather than a nice-to-have and the two audits look at much of the same markup.
It publishes no prices. Every tier is quote-only, which tells you the segment: if you are comparing monthly figures you are not the buyer. What you get for that is scale and a reporting layer built for communicating with stakeholders rather than for a specialist reading a URL export.
What you can use it for
- Crawl and monitor sites at a scale desktop and mid-market tools cannot reach
- Audit accessibility alongside technical SEO from the same crawl
- Report technical health to stakeholders who do not read URL exports
- Catch regressions through scheduled monitoring rather than periodic audits
The features that matter for SEO
Each one says what it does and the SEO job it serves. A vendor feature list without that second half tells you nothing you could not read on their own site.
Enterprise-scale crawling
Crawls very large sites on a schedule, with configurable crawl behaviour.
The reason it exists. At several million URLs the question stops being which crawler finds more issues and becomes which one finishes.
Health scores and visualisation
Summarises technical state as scores and charts intended for non-specialists.
Its customers cite this specifically — the layer that turns a crawl into something a stakeholder acts on rather than forwards.
Accessibility auditing
Audits pages against accessibility criteria with issue classification and descriptions.
Increasingly the reason enterprises buy a crawler at all, and it shares most of its underlying markup analysis with technical SEO.
Issue classification and prioritisation
Groups findings by type and severity with explanations.
On a site with tens of thousands of issues, classification is the difference between a report and a plan.
Scheduled monitoring
Re-crawls on a schedule and surfaces changes.
Catches a regression in the release it shipped in, which is the only point at which fixing it is cheap.
API access
Exposes crawl data programmatically.
Necessary at this scale — the analysis happens in a warehouse, not in the interface.
Pricing and limits
Starting price: Not publicly disclosed Checked 19 August 2026 Vendor’s own pricing page
Lumar does not publish figures for this product. Pricing is quote-only, so any number quoted elsewhere is somebody’s guess.
| Plan | Price | What it includes |
|---|---|---|
| All tiers | Not publicly disclosed | Lumar publishes no pricing for any plan. The site routes to a demo request rather than a checkout, which is consistent with its enterprise positioning. |
Strengths and limitations
Strengths
- Genuine enterprise crawl scale, where mid-market tools stop
- Health scores and visualisations built for communicating with stakeholders
- Accessibility auditing alongside technical SEO from one crawl
- Scheduled monitoring with issue classification
- A long track record under both names
Limitations
- No published pricing at any tier — every conversation starts with a sales call
- Enterprise-shaped, so overkill and likely unaffordable for a single site
- Not a research platform — no keyword database, no link index
- The rebrand means older documentation and tutorials still say DeepCrawl
Who it is for, and who should skip it
Worth it if
- Very large sites where crawl completion is the constraint
- Organisations where accessibility is a compliance requirement
- Teams who need technical findings communicated to non-specialists
Skip it if
- You want to know the price before talking to anyone
- Your site is small or mid-size — cheaper tools cover it properly
- You need keyword or link data in the same subscription

Questions
Is Lumar the same as DeepCrawl?
Yes. DeepCrawl rebranded to Lumar, and the vendor's own announcement confirms it. Documentation, tutorials and conference talks from before the change still say DeepCrawl, which is why the old name is kept searchable here.
How much does Lumar cost?
The vendor does not publish it. Every tier is quote-only and the pricing page routes to a demo request. Figures quoted for this product elsewhere cannot be checked against the vendor, so none appears here.
Why would I choose Lumar over a cheaper crawler?
Two reasons, both enterprise-shaped: crawl scale, where mid-market tools simply do not finish, and a reporting layer built to communicate technical findings to people who do not do SEO. If neither is your constraint, a cheaper crawler will find the same issues.
