Dyad

Dyad is an open-source AI app builder. It enables the generation of full-stack applications directly on a local machine, providing a development environment that avoids vendor lock-in and ensures that all generated code remains under the user's direct control.

The software operates as a web application that can be deployed on a local workstation. It is designed for users who want to build functional websites and applications using large language models while maintaining a private workflow. By running the environment locally, it removes the need for cloud-based subscriptions or external account management for the core building process.

Key features

• Local execution to ensure data privacy and faster response times
• Support for bringing personal AI API keys to avoid vendor lock-in
• Cross-platform compatibility for installation on Mac and Windows
• No sign-up requirement for users to start building applications
• Integration with multiple LLM providers including OpenAI and Anthropic
• Support for local model execution via Ollama
• Open-source core licensed under the Apache 2.0 license

Dyad is built for developers and AI enthusiasts who require flexibility in their choice of generative models. It supports a wide range of integrations, including Gemini, DeepSeek, and Qwen, allowing users to swap the underlying intelligence based on their specific project needs. The system is designed to handle the transition from AI-generated prompts to actual code residing on the local file system, which facilitates easier debugging and manual refinement of the software architecture.

Because it runs on the user's own hardware, it functions as a private AI website builder, catering to those who prioritize code ownership and local execution over managed hosting services.
