Reassure origins

From in-house project to Open Source*

We’ve created the Reassure to originally help one of our clients, Entain, in monitoring performance regression of React components in their app. Now, thanks to their willingness to develop the React & React Native ecosystem, we decided to make it Open Source. 

* Reassure is not Open Source yet but we will open the library’s repo in a few weeks. Until then, test the library by signing for the free early access by submitting the form above. Or below

how does it work?

Maintain high-performance stats of your React components

With Reassure developers will be able to write tests measuring the average rendering time of the in-app components and monitor these for each pull request in order to pro-actively notice performance issues.

Categorizing performance issues by their significance.

The tool is still in beta, but we want you to put your hands on it, test it and give us feedback essential for its further development.
