Dyad

Dyad is a free, open source AI app builder that runs on the desktop rather than in a hosted browser workspace. Users describe an idea in plain language and Dyad turns it into a working web app, with visual customization on top of real code that can be exported, opened in VS Code and run anywhere. It is available for macOS on Apple Silicon and Intel, and for Windows, with no sign up required for the free version. It suits builders who want the speed of prompt driven app generation without handing over their code or their model choice. Dyad works with OpenAI, Anthropic, Google and local models through Ollama or LM Studio, and users can bring their own API keys. It connects Supabase or Neon for databases, schemas, migrations and authentication, runs a built in security scan for issues such as SQL injection before shipping, deploys to GitHub and Vercel, imports existing repositories and extends through MCP servers. Recent releases added experimental Claude Code support and Cloudflare Workers publishing. Dyad Free costs nothing and includes the local app builder, bring your own key access and a Basic Agent capped at 20 messages a day. Dyad Pro is $20 per month and adds the Pro Agent, which automatically checks build errors, runs tests and debugs from logs, plus web search, website cloning, image generation, 200 AI credits a month and access to the Dyad Academy learning content. Dyad Max is $79 per month for building large, complex apps. Dyad charges a token orchestration fee of 1.5 credits per million tokens on some Pro access routes. Because the app runs locally and outputs standard code, projects stay fully portable if a user stops paying or leaves the tool.
