Our Take
v0 is Vercel's chat-based builder for apps and UI, aimed at people who want to go from prompt to a working React and Next.js project and collaborate on it. It has been shipping steadily: on Oct 6, personal accounts became team workspaces so anyone can invite collaborators, and on Oct 19 a Slack MCP integration arrived on all plans, letting v0 use a Slack thread as context or post updates. Since Sep 29, ChatGPT Plus and Pro subscribers can also connect their ChatGPT subscription to build in v0. Source
