dyad

Dyad is a free, local, open‑source AI app builder that runs on your desktop. It lets you describe an idea and generates a working web app without writing code, while keeping all files on your machine. The tool supports macOS (Apple Silicon and Intel), Windows and Linux distributions via .deb.rpm or AppImage packages.

You can start by typing a brief description of the app you want, examples on the site include an ecommerce store, a recipe planner or a startup CRM. Dyad then creates a full‑stack project using Next.js, adds a database and authentication layer, and produces clean, runnable code that you can edit in VS Code or any editor. The builder works with any AI model you prefer; you can switch between OpenAI, Anthropic, Google, Ollama or other local models, and you supply your own API keys. Because the process runs locally, there is no cloud lock‑in, no telemetry, and you retain 100 % of the source code.

For data handling, Dyad offers one‑click connections to Supabase or Neon, generating schemas, migrations and auth tables automatically. A built‑in security scan checks for SQL injection, misconfigurations and OWASP best practices before you deploy. Deployment options include one‑click publishing to GitHub and Vercel, or you can use your own hosting. The platform also provides a plug‑in system called MCP that lets you add Chrome DevTools, web browsing, custom APIs or other server‑side extensions.

Dyad's free tier includes the core app generation, model selection, local development and deployment features. A paid Pro tier adds higher AI credit limits, larger code‑base handling modes and access to Dyad Academy, while a Max tier raises the credit allowance further and offers prioritized office‑hour support. All plans are described as “no lock‑in,” and the software is released under an open‑source license with a public GitHub repository.
