Testimonials

Leonardo Faria

Senior Front-end Architect

A tool that I really like is @Relative_CI, already in 3 codebases here and it helps a lot analyzing the impact of a dependency in your bundle size

In this screenshot (educational PR), adding moment().format() increases the bundle size in 7%. Good for code review suggestions

Julian Perelli

CTO

RelativeCI helped us detect big size bundles before they reach production. It removes the stress of forgetting an important check that we used to do manually.
