Bugster is an AI testing agent that automatically generates, runs, and evolves end-to-end tests via real browser runs on pull requests commenting only when failures occur, preventing regressions and speeding up deployments.
Key Features
- Auto-discover real user paths and generate human-readable E2E tests from them (via Playwright) with no manual scripting
- Self-healing test suite: AI rewrites broken selectors when DOM/UI changes, reducing maintenance by ~80%
- Triggered on pull requests and preview deployments (e.g. Vercel, GitHub), runs only the relevant test subset and comments failures in PRs
- Destructive agent explores edge cases in previews to catch hidden regressions early
- Rich GitHub integration: test results, screenshots, video logs, and performance metrics visible inline with PR checks.
Use Cases
- Automated regression protection: Catch UI bugs before merging without writing test scripts
- Test coverage scaling: Add 50+ reliable tests in weeks by capturing production user flows
- Continuous CI/CD validation: Run selective tests on every pull request and preview build
- Reduced QA overhead: Teams integrate Bugster to minimize manual test upkeep
- Fast onboarding & transparency: Non-technical team members review visual test logs and metrics directly in PRs
