What engineering leaders say.
“Bug0 is the AI QA platform behind Prospyr, the practice management software for aesthetics clinics. It tests our web app continuously and points us to exactly where the app broke when something fails. We catch issues early instead of in production, which keeps a HIPAA-compliant product stable.”

“Bug0 is the closest thing to plug-and-play QA testing at scale. It's helped us catch multiple bugs before they made it to prod.”


“We build healthcare compliance software, so accuracy and reliability are non-negotiable. Bug0 provided us with an AI-based QA layer without adding headcount or another tool for my team to learn and manage. The tests run against all of our QA instances on a regular basis, providing us with a level of coverage and confidence that previously required many resources. We can focus our team on new development and real issues, and that's the part I care most about.”

“We plugged Bug0 into our CI and had our critical flows covered within a week. Like having a proactive QA engineer reviewing every deploy.”

“Bug0 is the AI QA platform behind Ferra, AI estimating software for steel construction. AI-based testing and execution with a forward deployed engineer who verifies every result, so we catch real bugs before production instead of chasing false positives. We see exactly where things broke, and we ship with confidence.”

“Bug0 gives us the speed of AI-native automation with the accuracy of human QA. We stopped worrying about flaky tests entirely.”

“We'd been putting off test coverage for months. Bug0 had our critical flows covered in under a week. No scripts, no maintenance burden.”

“We used to skip regression tests before releases because they took too long to maintain. Bug0 runs them on every PR now. We haven't shipped a regression in three months.”

Stop babysitting your test suite.
Legacy tools break every time your frontend changes.
Bug0 is built for teams who ship fast. When a button moves or a class name changes, our AI finds the new path. Your build stays green.
