The Problem
After submitting a PR for review, both you and the reviewer have no idea which UI changes were made. The reviewer has to do the following to make sure that everything works as excepted:
- Check out the PR locally.
- Run the app in the simulator or on desktop.
- Execute the required flow (e.g. authentication) to reach the desired screen to review.
- Test out the screen in different states (e.g. empty, error, loading, etc.) or different configurations (e.g. dark mode, different locales, etc.).
That process is time-consuming that most reviewers skip it, and just settle down for only reviewing the code. By skipping the UI review process, the risk of introducing UI regressions increases significantly.

The Solution: Widgetbook Cloud
Widgetbook Cloud can help you doing UI Reviews in your browser without the need to check out the PR locally or the need to write any code to test the UI. You can easily see all the changes made in the PR and test them in different states or configurations.
Builds
Host a Widgetbook build for each commit without all the hassle of self-hosting. Simple and optimized for Widgetbook.

How Salto prevents UI problems while saving 50% of their time
Widgetbook is integrated and running in our build CI pipelines. So, every merge request triggers Widgetbook Builds to run the snapshot tests. If we made changes in code, Widgetbook shows which components stayed the same and which components had visual adjustments making it trivial to review visual changes and get the code merged. — Arthur Schenk, Mobile Team Lead at Salto
