Screaming Frog has a free version that crawls up to 500 URLs with most core features. The paid licence at £149/year (~$190) removes the 500 URL limit and adds Google Search Console integration, JavaScript rendering and custom extraction.
Screaming Frog is more affordable (£149/year vs Sitebulb from $13.50/month) and produces more raw data for technical SEOs who want maximum control. Sitebulb produces more visual, client-friendly reports with prioritised recommendations. Most agencies use Screaming Frog for technical analysis and Sitebulb for client reporting.
