About

Dyad is a flexible, local-first, open-source AI application builder. It provides developers and technology enthusiasts with a powerful platform to seamlessly integrate cutting-edge artificial intelligence capabilities into their own applications and workflows, all while maintaining complete control over data and privacy.

Key Features

Visual building: Use an intuitive drag-and-drop interface to connect AI models, data processing modules, and logic components, allowing you to create complex applications without writing extensive code.
Local deployment: Run fully offline on your own server or computer, ensuring sensitive data never leaves your environment and safeguarding privacy and security.
Open source: Built on an open-source license, you are free to view, modify, and distribute the code, and deeply customize it to meet your specific needs.
Multi-model support: Easily integrate a variety of mainstream open-source large language models (LLMs) and AI services to enable text generation, conversation, analysis, and other intelligent functions.
Modular design: Provides a rich set of pre-built modules and API interfaces, making it easy to extend functionality and integrate with existing systems.

Pricing & Fees

  • Pricing: The Dyad desktop app is free and open-source; a paid "Dyad Pro" option exists but plan details and prices are not publicly listed on the pages we reviewed; check the official site for current plans.
  • Free tier: The core app can be downloaded and used at no cost, with no cloud service fees or subscription required.
  • Bring your own keys: You supply your own API keys for OpenAI, Anthropic, Google, or free local models via Ollama and LM Studio, so model usage costs depend on your provider.
  • Platform availability: Available for macOS (Apple Silicon and Intel), Windows, and Linux (.deb, .rpm, and AppImage packages).
  • No lock-in: You keep 100% of your source code and can export clean, runnable code with no export or exit fees.
