Alloy vs v0

Alloy is a product prototyping and user-testing platform that can work from a connected codebase or capture pages through a browser extension. With a codebase connected, it can run an app and show changes live in a browser. Teams can make interactive prototypes, share them, run sessions and collaborate. The Free plan includes $5 credits per user per month, unlimited sessions and viewers, and 30+ integrations. Alloy lists Linear, Jira, Slack and Intercom among its integrations. Sessions can be exported, accessed through MCP or turned into GitHub pull requests; teams can also push changes to a pull request and roll them out to customers. The browser extension needs no setup. Connecting a codebase requires admin permissions and about 15 minutes. Free has standard support, Pro has priority support, and Enterprise has 24/7 support. Pro costs $20 per user per month. Enterprise pricing is custom and includes API access, an account manager, custom terms, and SAML + SCIM.

v0 is an AI agent for creating code, full-stack applications and other agents. Users can prompt it to build or refine projects, then deploy them to production or open a pull request for review. Documented project types include landing pages, dashboards, ecommerce stores, AI apps and full-stack applications. Design Mode provides visual controls and a live preview. In GitHub-connected chats, v0 creates a working branch and commits changes, but does not push directly to main. Previews run in isolated Vercel Sandbox environments that support server-side features such as API routes and databases. Its stated technology includes Next.js, React, TypeScript, Tailwind CSS and shadcn/ui. Integration topics include GitHub, Vercel, databases, Snowflake, Shopify, external APIs, MCP integrations and Slack. v0 is available on the web, iOS and API. The Free plan costs nothing and includes seven messages per day, Vercel deployment, Design Mode and GitHub sync. Plus is billed at $30/user/month; Business at $100/user/month.
