Paste your design rationale. Get a structured counter-argument.
Three rounds. A scored verdict. No encouragement.
Free tier — no account required
Describe the design decision you have made and why. A layout choice, a pattern, a product call. Any decision counts.
The opponent pushes back. Three rounds. Each harder than the last. You respond, clarify, fight for your position.
A structured score across four dimensions. Where your argument held. Where it cracked. What you missed entirely.
You have defended that decision four times this week. To your PM. To your lead. To yourself. But have you actively tried to break it? Stress-testing your own rationale before someone else does is what separates a designer who ships from one who stands behind what they ship.
Designers who use Design Sparring get their decisions challenged
before their stakeholders do.
I was certain about a navigation decision I had spent two weeks defending. By round two I could not hold my own argument together. We redesigned it the next morning.
The verdict flagged a blind spot I had been quietly skirting for a month. Cheaper and more honest than any design review I have sat through.
It does not tell you what to do. It makes you realize you did not actually know why you were doing it. That is the uncomfortable part. Also the useful part.
