You build. We test.
Smart AI handles your browser testing.
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 Testing (Bug0)
Built from the ground up
Result: True automation that works autonomously
AI-Washed Tools
Old tech with new labels
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
Explores your app autonomously, identifying critical user paths like signups, logins, and core product flows without breaking authentication.
- Intelligently navigates complex workflows
- Discovers hidden features and edge cases
- Prioritizes flows by usage and revenue impact
The result: Complete mapping of actual user journeys, not just documentation.
Test Creation Agent
Generates semantic locators and optimized execution strategies that survive UI changes and run 500+ tests in under 5 minutes.
- Creates tests that survive UI refactors
- Implements intelligent retry logic
- Builds modular components reducing maintenance by 90%
The result: Production-ready test automation from day one.
Test Maintenance Agent
Continuously monitors test execution, detects failing patterns, and automatically updates test logic when UI changes occur.
- Auto-detects and fixes broken selectors in real-time
- Analyzes failure patterns vs real bugs
- Maintains stability across browser updates and deployments
The result: Zero maintenance overhead with self-healing reliability.
Human QA Agents
Senior QA engineers with 10+ years experience validate AI decisions and ensure business-critical flows get human expertise.
- Validate test accuracy against business requirements
- Identify complex edge cases and integration points
- Provide detailed failure analysis with root cause recommendations
The result: Enterprise-grade confidence with automated speed and human precision.

Teams that ship faster with Bug0.
See how teams eliminate browser testing struggles with Bug0's managed QA service.
"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 caught critical bugs in our compliance flows that could have derailed our SOC 2 demos. The AI understands our app logic better than expected, and the human verification gives us confidence when stakes are high. It's like having a QA team that never misses anything."

Comprehensive testing suite
Coverage you can trust
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
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
Performance Testing
Checks that key pages and APIs load within expected time thresholds for optimal user experience
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
