Iterating on features used to involve a lot of slow manual testing. Now, we can verify visual changes really quickly and provide feedback to our developers very early on.
Saves a lot of back-and-forth!

Test more in less time

Catch visual bugs before they pose greater debugging challenges or even reach live users.

Make sure results align with designs across screen sizes and languages in our intuitive web app, making it far more effective than manual testing on physical devices.

How Appviewer helps MYBESTBRANDS to
innovate and iterate faster

Integrates with your stack

Use our SDKs or REST API to publish screenshots to your UI gallery. Easily integrate with your UI testing framework of choice and freely mock or simulate the UI states of interest.
If you already do snapshot testing, you can repurpose and publish your existing images.

Run from any CI/CD

Appviewer is designed to be run from your CI/CD pipeline. Capture and publish snapshots on push, PR, or release, or filter by selected branches. But for quick alignment of development snapshots, you can also run locally.
