Hey Product Hunt! 👋

I'm MOOOO. a product designer and the maker of StressFlow. 🚀

After years of designing interfaces, I kept coming back to one question:

What happens to a beautiful UI when things don't go as planned?

Longer text, unexpected content, complex Auto Layout structures, nested components… A design might look perfect in Figma but still break under real-world conditions.

That's why I built StressFlow — a UI stress-testing plugin for Figma.

It helps designers:

- Run 9 specialized UI stress tests

- Get resilience scores and actionable findings

- Spot potential issues before developer handoff

- Test safely without touching original designs

I wanted to make UI quality testing a natural part of the design workflow, not something we only think about after development.

You can try all 9 tests for free on your first run. If you find it useful, unlimited testing is just $7, one-time. No subscriptions.

I'd genuinely love your feedback!

What's the most frustrating UI issue you've discovered after handing a design to developers?

Thanks for checking out StressFlow! 💚
MOOOO.
