v0 alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Editor visual con IA para apps en React: haz clic en un elemento, rediséñalo y deja que el modelo escriba el código.
licenseApache-2.0
runsyour machine or their cloud
installHosted signup, or self-host with Bun or Docker plus Supabase configuration
enginesOpenRouter plus configurable code-edit services such as Morph or Relace
dataProject code lives in the workspace or sandbox; application metadata and assets use the configured Supabase instance
the catch vs v0It works best around a real React or Next.js codebase and is weaker than v0 at turning a brief directly into a polished standalone component.
setupHosted access may be gated; self-hosting needs Bun or Docker, Supabase and several environment variables

Describe un componente y velo renderizado en vivo, con salida como HTML, React o Svelte.

runsyour machine or their cloud
installDocker image or Python and uv source installation
enginesOpenAI, Groq, LiteLLM-compatible providers, LocalAI and Ollama
dataGenerated code and session state live in the running instance and browser; prompts go to the selected model backend
the catch vs v0It lacks v0's polished component library workflow, project persistence and direct Vercel deployment path.
setupDocker or a Python environment plus an API key, unless a compatible local model server is already running

Genera una app en React con un prompt, previsualízala localmente y luego quédate con los archivos y los errores.

runson your machine
installDesktop installer
enginesOpenAI, Anthropic, Google Gemini, OpenRouter-compatible providers and local Ollama
dataGenerated project source and app metadata stay on the computer; prompts and selected context go to the chosen provider unless a local model is used
the catch vs v0It is a broader local app generator, but it is less polished for component-specific generation, design-system reuse and Vercel-native handoff than v0.
setupA model-provider API key or a separately installed and configured local Ollama model

|---|---|---|---|---|---|
| Onlook | Apache-2.0 | docker to self-host | web, self-hosted | 26,433 | 2026-07 |

People still pay for v0 because the UI can be copied, but high-quality code models, context ranking, safe execution, and constant evaluation are the product. The recurring cost buys model changes, indexing, prompt injection, tool permissions, sandboxing, evaluation, telemetry choices, and IDE compatibility, not just the visible interface. If none of that applies to you, any pick above saves $360 a year.
Is there a free alternative to v0?
Yes: Onlook, OpenUI, Dyad. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own v0?
Our verdict is NO TANTO. A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For v0, generate React components from a brief and write them into a local project with previews. The hard boundary is vercel models, design tuning, component data, deployment, and ecosystem integration, plus frontier models, context infrastructure, and execution safety. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/v0.
