One command. 25 testers.

A form abuser. A confused grandma. A skeptical buyer. An angry subscriber.
They find bugs, UX friction, and trust issues — then write them up with screenshots, priority scores, and fix suggestions.

Not a wall of AI text. A report you can actually work from.
breakit groups duplicate findings, scores them by priority, and shows what happened with screenshots and reproduction steps. You can skim the summary, jump into individual issues, or compare runs after fixes.
Good enough for a solo launch check. Structured enough to drop into a team workflow.

Point breakit at any public site or preview deployment.
Personas explore your site with real browsers
Each persona clicks, types, navigates, and tries to complete tasks from a different angle.
One report — everything scored and prioritized
Findings are deduplicated, scored 0-100, and packaged with screenshots and repro steps.
Personas explore independently, share findings to avoid duplicates, and produce a single scored report.
Browser mode: full interactive sessions | Snapshot mode: page screenshots + structure analysis, faster
Why Not Just Ask ChatGPT?

Lighthouse checks technical quality. breakit checks whether the experience makes sense to different kinds of people. You probably want both.
Use It Before Deploys, Not Just Before Launch
breakit can run in GitHub Actions, emit SARIF, and fail the build when findings cross your severity threshold.
Your test suite tells you whether the flow still works. breakit helps tell you whether the flow still makes sense.
Run in CI
Use the GitHub Action and test every deploy.
