About Lumar (formerly DeepCrawl)
Lumar, evolved from its legacy as DeepCrawl, is a high-performance website intelligence platform engineered for the 2026 digital landscape where technical health and accessibility are paramount. Its architecture centers on a proprietary cloud-based crawling engine capable of processing millions of URLs with high-fidelity JavaScript rendering.

In 2026, the platform utilizes advanced machine learning to prioritize technical debt based on potential ROI, moving beyond simple error reporting to predictive performance modeling. It serves as a centralized source of truth for SEO, Engineering, and Product teams, facilitating cross-functional alignment on site speed, mobile usability, and WCAG 2.2 compliance. By integrating directly with BigQuery and providing a robust GraphQL API, Lumar allows for deep data democratization across enterprise business intelligence stacks, making it the gold standard for large-scale web ecosystems undergoing continuous delivery.
