Built AI-first, not AI-flavored.
Bug0 is the only QA platform architected from the ground up with AI agents that think, learn, and test like humans. While others bolt AI features onto old frameworks, we rebuilt testing entirely around artificial intelligence.
The AI-Washing Problem
Most "AI Testing" Tools Are Just Legacy Platforms in Disguise
The Hard Truth
90% of testing tools and agencies claiming to be "AI-first" are still using the same manual processes from 10 years ago—they just hand their QA engineers generic AI tools like ChatGPT to help write test scripts faster.
Real AI-Native Testing
Built from the ground up
Result: True automation that works like magic
AI-Washed Tools
Old tech with new labels
Result: Same old problems, shinier packaging
Don't settle for AI-washed testing.
Experience true AI-native QA automation that actually works as promised.
Our unique approach.
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 app like a curious power user with photographic memory.
Our AI doesn't just crawl your site—it understands context, remembers state changes, and builds a comprehensive mental model of how real users interact with your application.
The result: Complete test coverage of your actual user journeys, not just what's in your documentation.
Test Creation Agent
Transforms discoveries into enterprise-grade test automation.
Using advanced behavioral modeling, this agent generates self-healing tests that adapt to UI changes and maintain stability across deployments—no more brittle selectors or flaky automation.
The result: Production-ready test automation that actually works in your CI/CD pipeline from day one.
Human QA Agents
Expert oversight that brings precision to AI-generated testing.
Senior QA engineers with 10+ years of experience review every AI decision, ensuring your business-critical flows get the human judgment and domain expertise that automation can't replicate.
The result: Enterprise-grade testing confidence with the speed of automation and accuracy of human expertise.
Benefits for you.

Teams that ship faster with Bug0.
See what our customers have to say about their experience with Bug0's QA automation.
"Bug0 integrates seamlessly into our workflow and delivers instant value. The automated test coverage gave us confidence to ship faster while maintaining quality standards."
"Bug0 is the closest thing to plug-and-play QA testing at scale. Since we started using it at Dub, it's helped us catch multiple bugs before they made their way to prod."
"Bug0 just works. It runs behind the scenes, catches real issues early, and saves us hours every week. It's like having a full QA team without the overhead."

Bug0 provides a complete suite of testing capabilities to ensure your application is thoroughly validated across all dimensions.
End-to-End (E2E) Testing
Simulates real user behavior to validate entire flows from start to finish across your complete application stack
Regression Testing
Confirms that recent changes haven't broken previously working features
Smoke Testing
Runs a basic set of tests to ensure the core functionality is stable after a build
Performance Testing
Checks that key pages and APIs load within expected time thresholds for optimal user experience
API Contract Tests
Validates that your APIs return the correct structure, types, and status codes
Accessibility Testing
Detects accessibility issues using tools like axe-core to ensure compliance
Visual Regression Testing
Compares UI snapshots to catch unexpected layout or style changes
Cross-Browser Testing
Runs tests across Chromium, Firefox, and WebKit for maximum browser coverage
Flaky Test Detection
Automatically spots and isolates unstable tests that pass or fail inconsistently to maintain reliability
Mobile & Device Testing
Runs tests on real desktop and mobile devices on request, not just emulators
Network Mocking
Intercepts and simulates network responses to test edge cases and failures
Authentication Testing
Automates login flows and session-based behavior using browser storage state
Localization Testing
Verifies your app works correctly across different languages and regions
