Automated Performance Regression Testing with Reassure
As developers we love to dive into performance metrics, benchmarks, compare one solution to another. Whether we enjoy it or not, we’re often required to fix performance issues in our React and React Native apps. But this process is not sustainable and prone to regressions, especially as the app and team grow. What’s worse, those issues are often discovered by your users, making their experience miserable.

Spotting problems before they hit production.
