Our build verdict for v0 is NOT REALLY (use a free alternative, save the tokens). A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For v0, generate React components from a brief and write them into a local project with previews. The hard boundary is vercel models, design tuning, component data, deployment, and ecosystem integration, plus frontier models, context infrastructure, and execution safety.
