Why Live Demos Are the Ultimate Product Pressure Test

Screenshots are a presentation. Live demos are a contract. The difference is whether the product has to keep working while a stranger tries to break it.

When we shipped the OTF live demos — saas.otf-kit.dev and fitness-preview.otf-kit.dev — we told ourselves it was for marketing. It wasn't. The marketing was a side effect. The real reason a click-through demo exists is that it forces the product to survive contact with someone who wants to find the seams.

A screenshot is a single frame, picked from the best run, on the right data, in the light theme, at desktop width. A live demo is none of those things. It's every frame, every run, on whatever data the visitor invents, in whatever mode they toggle, at whatever viewport they resize to.
