PricingFreemium· Hobby: Free · Individual: $20 / mo. · Teams: $40 / user / mo. · Enterprise: CustomFree· Free and open-source (Apache-2.0). Hosted demo at openui.fly.dev is free; self-hosting is free but you pay for whatever model API keys (OpenAI, Anthropic, Groq, Gemini, Cohere, Mistral) you plug in, or run local models via Ollama at zero token cost.

Pros
  • Best-in-class multi-file edits
  • Choice of underlying models
  • Composer agent is genuinely useful
  • Tab completion is faster than Copilot
  • Fully open source under Apache-2.0 with an active W&B-maintained repo
  • Model-agnostic: OpenAI, Anthropic, Gemini, Groq, Cohere, Mistral, plus local Ollama models via LiteLLM
  • Live in-browser preview of generated HTML/Tailwind with iterative edit prompts
  • Converts generated components to React, Svelte, Vue, or Web Components on demand
  • Runs locally via Docker or source, so prompts and code never leave your infra
  • Ollama support means you can prototype UI with zero API cost on your own hardware
  • Good teaching artifact for prompt-driven, LLM-assisted frontend work
Cons
  • Heavier than vanilla VS Code
  • Pricing creeping up
  • Some extensions lag VS Code
  • Public demo at openui.fly.dev is a shared instance and is frequently down or rate-limited (502s are common)
  • Bring-your-own-key: no managed billing, no team accounts, no SSO out of the box
  • Output quality tracks the underlying model; small local models produce noticeably weaker layouts
  • Generated code is component-scoped scaffolding, not a full design system with tokens, a11y audits, or tests
  • No native integration with Figma, Storybook, or existing component libraries
  • Self-hosting requires Docker/Python know-how and your own model credentials
