GlassboxGlassbox is best understood as a suite.
Glassbox provides session replay with auto-capture of every user interaction, AI-driven struggle detection (rage clicks, error clicks, form abandonment), funnel analytics, conversion funnels, and compliance-focused data handling for regulated industries (financial services, healthcare, retail). It markets specifically at enterprise teams that need compliant session recording with PCI DSS and GDPR data protection built in.
DeepSEOAnalysisDeepSEOAnalysis is an ungated audit.
DeepSEOAnalysis audits technical SEO, structured data, and Core Web Vitals. Where Glassbox shows you individual sessions where users struggled, DeepSEOAnalysis measures the aggregate CWV data (CrUX p75) that explains why users struggled — a high INP score means every user on that page has a slow interaction response, not just the ones captured in replay. Together they provide quantitative (CWV) and qualitative (session replay) views of the same performance problems.
