Built AI-first, not AI-flavored.
Test coverage that actually works.
Bug0 isn't a QA tool or agency with AI bolted on. It's built AI-first, with agents that test your product like real users and humans where it counts.

Userflow Agent
Understands your app like a real user.
The AI Userflow Agent begins by exploring your app like a curious power user with no instructions needed.
- ✓Clicks buttons, opens modals, fills forms, and navigates tabs autonomously.
- ✓Identifies key flows like signups, logins, dashboard actions, and core product paths
- ✓Maps out the critical user journeys that truly impact your business.
Why it matters: Most testing tools need manual scripts. Bug0 figures out what to test on its own.
Test Creation Agent
Turns user flows into maintainable tests.
Once your flows are mapped, the Test Creation Agent auto-generates robust, browser-based tests.
- ✓Uses real context from the Userflow Agent instead of random crawling.
- ✓Structured to be resilient, with logic to handle dynamic content.
- ✓Runs on headless browsers by default, with real devices available on request.
- ✓Designed for modularity and reusability behind the scenes.
Why it matters: You get reliable, production-grade test coverage without writing a single line of code.
Human QA Agents
Precision and judgment where it matters.
AI handles most of the heavy lifting. Our Human QA Agents cover the last-mile precision.
- ✓Review tests daily and cover edge cases.
- ✓Flag flaky behavior, refine logic, and verify high-risk flows.
- ✓Collaborate with your team in Slack and share detailed video replays of failures.
Why it matters: AI gives you scale. Human agents bring the trust and stability automation alone can’t.
Benefits for you
No test cases to write
Our AI agents automatically generate and maintain your entire test suite.
No flaky test maintenance
Self-healing tests adapt to UI changes without manual updates.
No waiting for coverage
Run over 200 tests in under 3 minutes with high-speed parallel execution.
No complex setup
Just connect your staging URL and reach 100% coverage of critical flows in 7 days.
Where others bolt on AI, we built on it.
"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."
Coverage you can trust.
End-to-End (E2E) Testing
Simulates real user behavior to validate entire flows from start to finish
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
Flaky Test Detection
Automatically spots unstable tests that pass or fail inconsistently
Performance Test
Checks that key pages and APIs load within expected time thresholds
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
Mobile & Device Testing
Runs tests on real desktop and mobile devices on request, not just emulators
Network Mocking & Offline Testing
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
