Dyad

Dyad is a free, local, open-source AI app builder that runs on your computer and avoids lock-in to hosted platforms. It provides a downloadable desktop application for macOS (Apple Silicon and Intel) and Windows, a quickstart workflow to get an app running in minutes, and an optional Pro upgrade for additional AI credits and modes. Dyad emphasizes local control, templates, and integrations so builders can bring their own API keys and deploy full-stack AI apps.

• Local, open-source app builder — run and iterate on apps on your machine to retain ownership and decentralize development.
• Downloadable desktop apps — install and run Dyad on macOS (Apple Silicon and Intel) or Windows for offline-first development.
• No sign-up required — start building immediately and bring your own API key to connect models and services.
• Templates and quickstart — use starter templates and the quickstart guide to create a working app in minutes.
• Integrations — connect common services (examples in docs) to add databases and CI workflows.
• Pro modes and AI credits — optional paid tier offers additional AI credit management and enhanced modes for production usage.

To get started, download the desktop app for your OS, follow the quickstart in the docs, add a model API key or local model, pick a template, and iterate locally. Upgrade to Pro when you need managed AI credits or advanced modes.
