Vercel rebuilt v0 to tackle the 90% problem: Connecting AI-generated code to existing production infrastructure, not prototypes

Before Claude Code wrote its first line of code, Vercel was already in the vibe coding space with its v0 service.

The basic idea behind the original v0, which launched in 2024, was essentially to be version 0. That is, the earliest version of an application, helping developers solve the blank canvas problem.  Developers could prompt their way to a user interface (UI) scaffolding that looked good, but the code was disposable. Getting those prototypes into production required rewrites.

More than 4 million people have used v0 to build millions of prototypes, but the platform was missing elements required to get into production. The challenge is a familiar one with vibe coding tools, as there is a gap in what tools provide and what enterprise builders require. Claude Code, for instance, generates backend logic and scripts effectively, but does not deploy production UIs within existing company design systems while enforcing ...
