Move fast, without
breaking things

Unit tests pass. Code review looks good. Production breaks anyway. Close the gap between what you test and what actually happens with your users.

Record live traffic on production or staging

Trace your service to capture real user requests on your app––HTTP traffic, DB queries, Redis calls, and more––which can be stored locally or in Tusk Cloud
