"AI-Native QA Automation That Makes End-to-End Testing Accessible"

5/5

What do you like best about Thunders?

We use Thunders at Uptale and I’ve been really impressed by the product.

What stands out is the AI-native approach to QA automation. Plain-language test authoring combined with an agent that actually drives the browser makes testing much more approachable than maintaining traditional scripted test suites.

I especially like that it makes test automation accessible to our Product team, not just developers, so the people defining features and user flows can contribute directly to end-to-end testing. It also addresses a very concrete pain point for us: reducing the amount of manual regression testing we have to do before releasing to production.

The direction around reducing brittle test maintenance and making broader end-to-end coverage easier to achieve is very compelling. Review collected by and hosted on G2.com.

What do you dislike about Thunders?

There’s quite a lot the product can do, so it takes a bit of time initially to understand how to get the most out of it and how to best integrate it into our existing QA and product workflows.

More guidance, templates and best-practice examples for different testing scenarios would make that initial adoption even easier. Review collected by and hosted on G2.com.

What problems is Thunders solving and how is that benefiting you?

Thunders is helping us address a very concrete problem: the amount of manual regression testing required before releasing to production.

By making end-to-end test automation accessible in plain language, our Product team can contribute directly instead of relying only on developers to write and maintain automated tests.

The benefit is the potential to automate more of our regression coverage, reduce repetitive manual testing before releases, and ultimately ship with more confidence. Review collected by and hosted on G2.com.
