Built AI-first, not AI-flavored.
Bug0 is architected from the ground up with agentic AI that thinks, learns, and tests like humans. While others bolt AI features onto legacy frameworks, we rebuilt browser testing entirely around artificial intelligence.
The AI-Washing Problem
Most "AI Testing" Tools Are Just Legacy Platforms in Disguise
The Hard Truth About AI-Washed Testing
90% of testing tools claiming to be "AI-powered" are still using manual processes from 10 years ago—they just give QA engineers ChatGPT to write test scripts faster.
AI-Native vs AI-Washed Testing
See the difference between true AI automation and marketing labels
Bug0 (AI-Native)
Built from the ground up
Others (AI-Washed)
Old tech with new labels
Result: True automation that works autonomously
Result: Same old problems with AI marketing
Don't settle for AI-washed testing.
Experience true AI-native QA automation that actually works as promised.
Powered by AI agents that work
the way humans test.
Our platform combines intelligent algorithms with human expertise to deliver reliable testing results.
Userflow Agent
Maps your web app like a power user
Explores your app autonomously, identifying critical user paths like signups, logins, and core product flows without breaking authentication.
Result: Complete mapping of actual user journeys, not just documentation.
Test Creation Agent
Self-healing browser tests
Generates semantic locators and optimized execution strategies that survive UI changes and run 500+ tests in under 5 minutes.
Result: Production-ready test automation from day one.
Test Maintenance Agent
Real-time healing & updates
Continuously monitors test execution, detects failing patterns, and automatically updates test logic when UI changes occur.
Result: Zero maintenance overhead with self-healing reliability.
Human QA Agents
Human judgment for AI automation
Senior QA engineers with 10+ years experience validate AI decisions and ensure business-critical flows get human expertise.
Result: Enterprise-grade confidence with automated speed and human precision.
