Product Introduction

1. Dyad is a free, local, and open-source AI app builder that enables users to create full-stack applications through natural language conversations with AI, eliminating the need for traditional coding.
2. The core value of Dyad lies in its commitment to user ownership and flexibility, offering a vendor-agnostic platform that supports any AI model (including free tiers like Gemini 2.5 Pro) and ensures full control over source code and data privacy through local execution.

Main Features

1. Dyad integrates with Supabase for backend services, allowing users to implement authentication, databases, and server functions directly within their AI-generated apps, enabling full-stack development without external dependencies.
2. Users can leverage multiple AI models (e.g., OpenAI GPT-4.1, Claude Sonnet 3.7, Gemini 2.5 Pro) with their own API keys, including 25 free daily messages via Gemini, while retaining the option to run local models through Ollama for complete data isolation.
3. The tool operates entirely offline on Windows and macOS devices, providing instant previews, real-time editing feedback, and seamless integration with IDEs like VS Code, ensuring compatibility with existing development workflows.

Problems Solved

1. Dyad addresses vendor lock-in limitations common in cloud-based AI builders (e.g., v0, Bolt) by enabling full code ownership, local execution, and compatibility with self-hosted or third-party AI services.
2. It serves developers, indie hackers, and non-technical users who require rapid prototyping of AI-powered applications without sacrificing control over infrastructure or data privacy.
3. Typical use cases include building secure internal tools, creating customer-facing web apps with integrated authentication, and experimenting with multiple AI models simultaneously for cost optimization.

Unique Advantages

1. Unlike competitors, Dyad combines open-source code availability (hosted on GitHub) with native desktop operation, eliminating cloud runtime fees and enabling offline functionality unavailable in browser-based alternatives.
2. The platform uniquely supports hybrid AI model usage, allowing simultaneous integration of cloud-based APIs (e.g., OpenAI) and locally hosted LLMs via Ollama within the same application architecture.
3. Competitive advantages include zero subscription costs for core features, GDPR-compliant local data processing by default, and real-time collaborative editing capabilities through its native desktop interface.

Frequently Asked Questions (FAQ)

1. How does Dyad ensure data privacy compared to cloud-based alternatives? Dyad processes all data locally on your machine, never transmitting app logic or user information to external servers unless explicitly configured for specific AI API calls.
2. What AI models are supported in Dyad? The platform works with any model accessible via API keys, including Gemini 2.5 Pro (25 free daily messages), OpenAI GPT-4, Claude Sonnet 3.7, and local models through Ollama, with no forced vendor partnerships.
3. What are the system requirements for running Dyad? Dyad requires Windows 10/11 or macOS (Intel/Apple Silicon) with minimum 8GB RAM, though local model execution via Ollama demands additional GPU resources for optimal performance.
4. Is Dyad truly open-source? Yes, the entire codebase is MIT-licensed on GitHub, allowing users to audit, modify, and self-host the builder while retaining commercial usage rights without royalties.
5. How does Supabase integration work in Dyad? Users authenticate once with Supabase to automatically provision databases, auth services, and serverless functions within their AI-generated apps, with full control over Supabase project settings.
