What session replay actually shows you
Session replay records mouse movements, clicks, scrolls, and form interactions. You can replay a user's entire session like a video. When correlated with an error event, it shows exactly what the user was doing before the bug appeared.
When it's genuinely useful
- Debugging bugs you can't reproduce — see the exact steps that triggered it
- Understanding dropoffs — why are users leaving the signup flow at step 2?
- Validating UI decisions — are users finding the feature you just built?
- Investigating support tickets — "the user said it wasn't working" → watch their session
The privacy considerations
Session replay can capture sensitive data if not configured carefully. Always: mask input fields by default, exclude pages with financial data, comply with GDPR by getting consent. ProdFix masks sensitive fields automatically.
For solo founders: the honest verdict
Session replay is valuable but not critical for every project. You don't need it if: your app is simple, you have low traffic, you don't have conversion optimization as a current priority. You do need it if: you're debugging mysterious user complaints or trying to improve onboarding.
Getting it without a dedicated tool
ProdFix includes session replay context as part of its error monitoring — you don't need a separate tool. When an error is captured, the session replay for that user session is automatically available in the error details.
