What is Lumar?
Lumar runs cloud-based crawls for sites selected by its customers and turns the fetched page data into private website analytics. The service was previously named Deepcrawl, so current traffic may still carry that older name. It does not crawl the open web for a public search index.
A project can discover pages through site links or supplied sitemaps, render JavaScript when configured, and select a search-engine, browser, or custom user agent. Lumar says its own identifier remains in the request even when the crawler emulates another agent. Logs may therefore contain lumar, deepcrawl, or one of those strings appended to a longer browser-like header.
Customers set the crawl rate inside Lumar. The operator does not support the Crawl-delay directive, so changing that line in robots.txt will not slow the bot. If a crawl is putting pressure on the origin, the project owner should reduce its configured rate, while an unaffiliated site can use normal traffic controls.
Lumar now sells GEO analysis as part of its platform, but the crawler described here still gathers site data for the customer's reports. A fetch does not itself submit the page to an AI answer engine or a training corpus. Any later recommendation produced inside Lumar is separate from public indexing or citation.
