Like

Using remote servers and connections for running the automation tests is a good feature and helps in eliminating local configs leading to different outputs/errors.

Like

The autonomous AI agent Kane AI is amazing, where you can plan, author, execute and analyze tests using natural language prompts or company context across web, mobile, API, etc.

Dislike

1. Can be more cost effective - giving users packages with more users for the same account at the same time usage 2. We have test logs, which are the earlier tested history - for which if we can have browse and reuse the test logs option like web browser history usage - click and go to the respective used page, it would be very helpful. 3. Smart comparison page is not showing up the images properly - baseline image section and comparison image section Mobile Testing limitations 5. Limited Free tire

Dislike

Proper setup steps and submission details are challenging to understand which can be improved.

Dislike

The only minor dislike was the initial learning curve to fully leverage the multi-agent architecture, but the excellent documentation and support mitigated this.
