# Gravity AI UI vs Vercel v0

Compare Gravity AI UI with Vercel v0 for agent-readable UI generation, MCP access, A2UI payloads, OpenAPI docs, and React export workflows.

## Vercel v0 fit

Vercel v0 is a strong fit for fast React UI drafts and code-first product prototyping inside a Vercel-centered frontend workflow.

## When to choose Gravity AI UI

Choose Gravity AI UI when an AI agent needs a structured A2UI contract, MCP tools, OpenAPI discovery, markdown fallbacks, trusted Gravity UI rendering, and a React export it can inspect without scraping a visual canvas.

## When to choose Vercel v0

Choose Vercel v0 when the main job is producing front-end code drafts quickly and the agent does not need a remote MCP server or constrained Gravity UI component registry.

## What agents can reuse

Agents can reuse the composed payload, A2UI messages, public gallery metadata, generated React export, OpenAPI spec, and MCP tools.

## Trade-off

Gravity AI UI is narrower than v0: it focuses on product-interface surfaces and agent workflows rather than broad app scaffolding.
