Why use Stably AI?

Minimum maintenance burden on developers.

fewer revenue-losing bugs
faster than manual testing
reduction in developers' time on writing & maintaining tests
The best money our team has spent. Thanks to Stably, we saw a big increase in user conversion rates due to the fewer bugs we have. I want to thank the Stably team for making these results possible. Their only goal is to make software teams succeed and they are very good at it.
Siddhi Mittal, CEO
Stably's AI makes writing UI tests much easier than by hand. And these tests actually simulate the user flows end to end. We ran Stably tests in our CI / CD pipeline and have already caught some bugs that would have impacted users.
Vikas Vair, CPO
I used to be very nervous about our application breaking from new updates. After setting up tests on Stably, I have more assurance that our users won't run into most of the bugs anymore.
