:recycle: Visual Regression Testing tool

← Building the product

In simple English

This tool checks if your website design changed by accident. It compares new screenshots with old screenshots. It highlights any differences in a visual report. It saves the report in cloud storage like Amazon S3. You can run it on your own computer or on a server.

What it is

A command-line tool (a program that runs in your terminal window) for visual regression testing. It uses plugins to fetch old images, compare them, and send notifications.

What it is good for

Solo builders who want to make sure a code change does not break their website design.
