First Impressions
I typed 'A dark mode dashboard with a sidebar and chart widgets'. v0 generated three distinct variations in seconds. The code was clean, using shadcn/ui components. I copied it into my project and it just worked.
Best Feature: Iteration
You can chat with the result. 'Make the sidebar smaller' or 'Add a user profile dropdown'. It refines the code based on your feedback.
The Verdict
The fastest way to build frontend components. It kills the 'blank canvas' problem for React developers.
