01
Replay production
exactly as it happened
Flux captures the exact outcome of every API call and database query. Replay them locally without mock data or environment sync.
02
Fix bugs without
breaking anything else
Test your fixes safely. External services are never hit during replay, ensuring no duplicate emails, charges, or corrupt state.
03
Resume failed
requests instantly
Once fixed, resume the execution precisely from where it failed. No retries, no data loss, just progress.
