v0: the code-generation agent that opens its own app, uses it, and ships through your protected branch
Vercel's v0 has the most complete agent loop among closed full-stack generators: web search with clickable citations, a browser that actually uses the app it built and sends back screenshots, terminal and unit tests inside a sandbox, bring-your-own MCP for external tools, and since Sep 2026 a one-step Publish that walks PR to merge to deploy for GitHub projects. Its boundaries are equally clear: the default stack is Next.js + shadcn, the shortest path is locked to Vercel, credits scale with iteration rounds, and there is no public correctness benchmark.
