v0 by Vercel

v0 is Vercel's AI agent that generates full-stack web applications, React components, and UI designs from natural-language prompts, then deploys them directly to Vercel infrastructure. Launched in late 2023, v0 has expanded well beyond UI generation into a full agentic development platform: it combines web search, browser use, terminal command execution, automatic error fixing, and external tool integration into a single development assistant that operates inside an isolated Vercel Sandbox per chat session. Every agentic action is visible in real time with progress indicators, browser screenshots, and citation links. The integration depth distinguishes v0 from comparable vibe-coding tools. The Vercel Marketplace connects v0 natively to Neon, Supabase, and Upstash for databases; Stripe for payments; and AI model platforms, allowing v0 to query live data and manage resources during code generation rather than generating static mock data. MCP server support brings external tools including Linear, Notion, and Sentry into the generation context. GitHub sync enables clean pull request workflows. Figma import converts designs to working code. Snowflake integration supports data science workflows in Python and SQL. Automatic error diagnosis catches and fixes missing dependencies, syntax errors, runtime bugs, and deployment failures within the generation loop, including a "Fix with v0" button that appears directly in the Vercel deployment interface. v0's generated code uses Tailwind CSS, shadcn/ui, and Next.js App Router by default — the modern React stack that Vercel maintains and that has become the standard for new Next.js projects. Design Mode adds a visual editor on top of generated code for designers and product managers to iterate without touching code. v0 also supports Python, SQL, and data visualization for data science use cases via Snowflake, expanding the addressable audience beyond front-end developers. Pricing is tiered by credit usage. Free at $0/month includes $5 of monthly credits, Vercel deployment, Design Mode, GitHub sync, and a 7-message daily limit: sufficient to evaluate the platform and ship small projects. Team at $30/user/month adds $30 of monthly credits per user plus $2 in daily login credits, the ability to purchase additional credits outside monthly allocation, centralized Vercel billing, and team chat sharing. Business at $100/user/month adds training data opt-out by default and dedicated infrastructure. Enterprise pricing is custom and includes SAML SSO, role-based access control, priority infrastructure with no queues, and a guarantee that data is never used for model training. On-demand credit packs are purchasable on all paid tiers. Three model tiers are available for purchased credits: v0 Mini (fastest, $1/1M input tokens), v0 Pro (balanced, $3/1M input tokens), v0 Max (highest intelligence, $5/1M input tokens), and v0 Max Fast ($30/1M input tokens for rapid iteration). v0 is not the right fit for teams not on the Next.js and Vercel stack. Vue, Svelte, Angular, or non-Vercel-hosted projects are better served by Bolt.new or Lovable, both of which support broader framework and hosting options. Teams that need terminal-based workflows with full git control should evaluate Cursor at $20/month or Claude Code Pro at $20/month. The credit-based pricing model creates unpredictability for complex multi-file generation workflows: Team's $30/month credit allocation can exhaust quickly on iterative builds, and per-token costs for v0 Max at $25/1M output tokens can add up on demanding projects. Current state Q2 2026: v0 expanded from UI generation to full agentic development with the launch of web search, browser use, terminal commands, and Marketplace integrations. Snowflake integration added data science workflows. Three model tiers (Mini, Pro, Max, Max Fast) now provide credit flexibility. The Business tier training opt-out addresses a key enterprise procurement concern. v0 operates under SOC 2 Type II compliance as part of the Vercel platform. Vercel has raised $313M+ at a $3.25B valuation and serves millions of developers across the broader platform.
