v0 alternatives: 8 open-source picks
v0 costs $30/mo — $360 a year. These 8 alternatives replace it for $0, led by Onlook, OpenUI and Dyad. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Visual AI editor for React apps: click an element, restyle it, let the model write the code.
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 a component and see it rendered live, with output as HTML, React, or Svelte.
licenseApache-2.0
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

Prompt a React app, preview it locally, then own the files and the bugs.

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.

how to choose a v0 alternative
Easiest to get running
Dyad — a one-click install, no server to maintain.
Most proven
OpenCode, with 192,000 GitHub stars — the largest community of the 8, which usually means more answers when something breaks.
Runs on your own machine, no server
Dyad — nothing to host, your data stays on your disk.
what you give up by leaving v0
- Vercel models, design tuning, component data, deployment, and ecosystem integration
- frontier proprietary model
- large-scale code retrieval
- cloud sandbox fleet
- enterprise policy and support
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for v0
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.
