How do Hotjar and FullStory handle sensitive form fields and PII masking?

Both platforms provide automatic and manual masking capabilities. FullStory automatically masks all text input by default unless explicitly unmasked, making it robust for preventing accidental PII collection. Hotjar allows you to obscure specific CSS selectors or input types to ensure sensitive form data never leaves the user's browser.

Which tool is better suited for complex Single Page Applications (SPAs) typical in B2B SaaS?

FullStory is generally superior for complex SPAs because it indexes every DOM mutation and user interaction continuously, allowing you to search and replay intricate user journeys accurately without manual event configuration.

How does pricing scale between Hotjar and FullStory for high-volume session tracking?

Both platforms tier their pricing based primarily on session volume (monthly session counts). Hotjar's pricing scales up through tiered plans suited for smaller teams, while FullStory typically uses customized enterprise contracts tailored to heavy data ingestion and complex team permissions.
