The models' case: Purpose-built for frontend engineering debugging with deep React ecosystem integrations, providing synchronized state diffs (Redux, Zustand), React Router breadcrumbs. The models' main caveat: High enterprise pricing and client-side resource overhead make it cost-prohibitive for high-traffic consumer web applications requiring unsampled 100%. The strongest alternative is Sentry Session Replay — Ties each replay directly to the captured error, stack trace, breadcrumbs, and release for the exact React component that threw, which is the. Not unanimous: Claude picks Sentry Session Replay.
