Lumar

Fully verifiable

The site crawler behind Lumar's website analytics platform, formerly Deepcrawl, which crawls a customer's pages at enterprise scale to collect technical SEO, accessibility and site-health data. Lumar runs the crawl from its own addresses and publishes them, names two robots.txt tokens — its current and former brand — and warns site owners that its user agent may still reference the Deepcrawl name so that existing customer rules keep working. It states that it does not support the crawl-delay directive, aiming instead to match the way Google crawls.
