v0

v0 experiences frequent service outages, request processing failures, and data loss issues including deleted conversations, disappearing messages, and erased deployments. Users report being unable to rely on the tool for production work despite paying subscription fees.

v0 has broken Git integration, manual code edits vanish during later generations, exports produce blank screens or incomplete projects (missing pages), and sharing projects with teams is problematic. Code that works in v0 often breaks in production.

v0 strictly outputs React components and Next.js-compatible code only, forcing developers using Angular, Vue, Svelte, or other frameworks to perform extensive code conversion. The tool also mandates Tailwind CSS and doesn't generate TypeScript by default.

v0 generates only frontend UI components and cannot produce backend logic, database schemas, API communication code, authentication systems, or state management implementation. Developers must build all underlying functionality manually.
