Built for the Enterprise

Touca started as an internal tool at a medical software company to find regressions in low-level components of a mission-critical product.

"We use Touca to perform nightly regression tests of our critical workflows. When we make changes to complex software, we need to have confidence that there have been no unexpected consequences. Touca gives us that confidence by tracking millions of output values computed from thousands of input datasets and helping us understand exactly how those outputs have changed from one build to the next. That confidence gives us leverage to develop new features faster and with fewer problems."
