Can I open-source Sitebulb?
KINDA · partial or early alternativesKinda. FreeCrawl and LibreCrawl cover the core of Sitebulb, but they're early or partial — expect gaps like rule depth, visualization, reporting, JavaScript crawling, and agency workflow and massive hosted crawl capacity.
People still pay for Sitebulb because a crawler is buildable; professionals pay for years of edge-case handling and reports they can trust with clients. The recurring cost buys robots handling, rendering, canonicalization, deduplication, crawl traps, rule maintenance, scheduling, storage, and false positives, not just the visible interface.
