Why Bugster
For Developers Who Ship Fast
PR reviewers check your code. Bugster checks your product. It opens your preview and tests it like a user—making sure everything works before you hit merge.
Testing That Matches Your Speed
Bugster runs tests automatically as part of your workflow—no setup fatigue, no waiting.
Tested Where It Lives
Bugster evaluates your app in GitHub PRs, Vercel previews, localhost, or staging—wherever you build.
Only Real Issues, Right in Your PR
No noise. Bugster comments on PRs only when something's broken—so you can fix it before it hits prod.
Bugster handles E2E testing, so you don't have to
Automated testing that evolves with your application
Automatic test generation
Creates realistic user-flow tests automatically, stored as human-readable YML specs in your repo—no scripting required.
Zero-effort maintenance
Your YML test suite stays fresh automatically. Bugster continuously updates tests as your app evolves.
Smart test selection
Runs relevant tests according to your PR changes, reducing noise.
"Instead of running 100s of tests, Bugster runs just the 12 that matter."
Destructive agent
Aggressively stress-tests your UI in real previews, proactively finding issues.
PR-level reporting
Bugster comments only if something breaks—no false alarms. Get actionable feedback directly in your pull requests.
Perfect if you want full control and test locally first.
