Lumar
Enterprise website intelligence and technical SEO platform
About Lumar
Lumar (formerly DeepCrawl) is a cloud-based website optimization platform that crawls and audits large-scale sites for technical SEO, GEO/AEO (AI search) visibility, site speed, web accessibility, and custom metrics. Built for enterprise SEO, marketing, and web teams, it runs scheduled cloud crawls, monitors changes across multiple domains, and integrates with CI/CD to catch issues before they reach production. Brands such as Adobe, Microsoft, Comcast, and Deloitte use Lumar to maintain website health at scale.
Pros & Cons
Pros
- Cloud-based crawler scales to the largest enterprise websites (millions of URLs)
- Coordinated apps cover technical SEO, accessibility, site speed, and AI search in one platform
- CI/CD integration (Protect) catches SEO regressions before they ship to production
- Continuous monitoring with custom alerts across multiple domains and environments
- Clear health scores and visual dashboards make prioritization and stakeholder reporting easy
- Unlimited users included on all plans
Cons
- No public pricing — requires a sales conversation to get a quote
- Priced for mid-market and enterprise budgets; overkill for small sites or solo SEOs
- Breadth of reports and configuration options has a learning curve
- Cloud-only model is less suited to one-off desktop-style audits
