Build vs Fork Verdict: NOT REALLY (use a free alternative, save the tokens)

Why fork SiteOne Crawler instead of vibe-coding a Lumar clone?

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Lumar, run a limited technical crawl and maintain an auditable issue history. The hard boundary is enterprise crawl scale, monitoring, analytics, governance, and consulting support, plus crawl scale, rule depth, and operational polish.
