Session Replay

Session replay records real user sessions — clicks, scrolls, mouse movement, rage-clicks, and DOM changes — and lets you play them back like a video, though most tools reconstruct the page from captured events rather than recording actual video. It answers the question quantitative funnels can't: *why* did users drop off on this step? For SaaS builders, replay is how you catch a broken form field, a confusing empty state, or a button nobody notices — bugs and UX friction that never show up in aggregate metrics. Tools like PostHog, Hotjar, FullStory, and LogRocket pair replays with console logs and network errors so you can reproduce issues without asking the user for steps. Practical note: replay captures sensitive data by default, so mask password fields, PII, and payment inputs before shipping, and sample sessions rather than recording everyone once you have traffic — storage and privacy costs add up fast. Use it alongside funnels, not instead of them.
