Being towards death

Heed not to the tree-rustling and leaf-lashing rain, Why not stroll along, whistle and sing under its rein. Lighter and better suited than horses are straw sandals and a bamboo staff, Who's afraid? A palm-leaf plaited cape provides enough to misty weather in life sustain. A thorny spring breeze sobers up the spirit, I feel a slight chill, The setting sun over the mountain offers greetings still. Looking back over the bleak passage survived, The return in time Shall not be affected by windswept rain or shine.

AI-generated summary
Dyad is a local-first, open-source full-stack AI application builder designed as an "AI conversational development toolbox." Users can describe their requirements in natural language, and Dyad automatically generates the necessary front-end (React), back-end (Supabase), and database code, keeping all data on local devices. ### Key Features: 1. **Multi-Model Switching**: Supports popular models like Gemini 2.5 Pro, GPT-4.1, and Claude Sonnet, allowing users to avoid vendor lock-in. 2. **Deep Supabase Integration**: Enables quick MVP application setup with seamless authentication and database integration. 3. **Git-like Version Control**: Automatically creates code snapshots with each AI modification, allowing for easy rollbacks. ### Core Functionalities: - **Conversational Full-Stack Development**: Users can input commands to generate complete applications, with guidance for complex requirements. - **Cross-Platform Local Operation**: Supports offline use with 100% local data storage to mitigate cloud data leak risks. - **Multi-Model Scheduling**: Offers cost-effective model usage based on specific scenarios. ### Quick Start Guide: 1. **Installation**: Download the package for macOS/Windows and configure API keys. 2. **Application Creation**: Users can create apps by selecting a tech stack and entering prompts for code generation. ### Competitive Analysis: Dyad offers advantages in code ownership, data privacy, model flexibility, cost, and deployment freedom compared to competitors. ### Summary: Dyad is ideal for small teams and privacy-sensitive scenarios, transforming full-stack development from coding to requirement specification through AI, making it accessible for entrepreneurs, IT departments, educational institutions, and privacy advocates. ### GitHub and Website: - GitHub: [Dyad Repository](https://github.com/dyad-sh/dyad) - Website: [Dyad Official Site](https://www.dyad.sh)

Dyad: A Locally First Open Source Full-Stack AI Application Builder#

Dyad is a locally first, open-source, free full-stack AI application builder, positioned as an "AI Conversational Development Toolbox." Users describe their needs in natural language (e.g., "build a to-do app with login"), and Dyad automatically generates complete front-end (React), back-end (Supabase), and database code, with all code and data retained on local devices.

Technical Breakthroughs#

  • Multi-Model Switching: Supports mainstream models like Gemini 2.5 Pro, GPT-4.1, Claude Sonnet, and allows for custom models. Users can bring their own API keys to avoid vendor lock-in.
  • Deep Supabase Integration: Seamlessly connects authentication, databases, and server-side functionality, enabling MVP applications to be built in 5 minutes.
  • Git-style Version Management: Automatically generates code snapshots with each AI modification, supporting one-click rollback.

Four Core Features Tested#

1. Conversational Full-Stack Development#

Example Input Command
"Build a user login system with Google authentication, storing data in Supabase"

Output Results:

  • Automatically generates React front-end login page + back-end Auth logic
  • Configures Supabase user table and API interface
  • Pitfall Reminder: Complex requirements need to be broken down into multiple commands (e.g., first define the data model, then design the UI)

2. Cross-Platform Localized Operation#

Deployment Options:

  • One-click installation for macOS/Windows, offline available
  • 100% local data storage, eliminating cloud leak risks
  • Tech Stack: TypeScript (96.9%) + React + Supabase, code can be exported to VSCode for further development

3. Multi-Model Hybrid Scheduling#

Recommended Model Types and ScenariosCost Advantages
Gemini 2.5 ProLong text logic generation, utilizing daily free quota
Ollama Local ModelSensitive data processing, zero API costs
GPT-4.1Complex code generation requires a paid key

Quick Start Guide#

1. Installation and Configuration#

  • Download the installation package (supports macOS/Windows)
    Visit the official website https://www.dyad.sh/ to download

  • Configure API Key (using Gemini as an example)

    1. Left sidebar Settings → AI Providers → Google Gemini
    2. Paste API key → Save

2. Create an Application#

  1. Click "New App" → Select tech stack (recommended Next.js)
  2. Enter prompt: "Create a blog system that supports Markdown editing and commenting"
  3. Wait for AI to generate code → Real-time preview interface
  4. Click "Export" to deploy to GitHub/Vercel

Competitor Comparison Analysis#

CapabilityDyadv0/LovableBolt
Code Ownership✅ 100% Local Open Source❌ Cloud Closed Source
Data Privacy✅ No Cloud Transmission❌ Data Uploaded to Vendor Servers
Model Flexibility✅ Supports Any API/Local Model❌ Locked to a Single Vendor
Cost✅ Core Features Free Forever❌ Subscription-Based ($20+/month)
Deployment Freedom✅ Can Export to Any Platform❌ Limited to Exclusive Hosting
Limited Customization💡⚠️

Advantages Summary#

Privacy control + zero cost + full-stack generation, suitable for small to medium teams and privacy-sensitive scenarios.

Developer Extension Tips#

Performance Tuning Parameter Example Configuration Recommended Values

  • maxToken: 2048 — Controls the length of AI-generated code
  • temperature: 0.3 — Reduces randomness, enhances code stability
  • localFallback: true — Automatically switches to local model during network interruptions

Conclusion: Who Should Pay Attention to Dyad?#

Core Value: ✨ Transforming full-stack development from "writing code" to "stating requirements" — lowering technical barriers through AI dialogue while ensuring data sovereignty.

Applicable Scenarios:

  • Entrepreneurs: Zero-code validation of product ideas, saving initial development costs
  • Corporate IT Departments: Rapidly building internal tools (e.g., contract review, customer management)
  • Educational Institutions: Teaching full-stack development and AI integration practices
  • Privacy Advocates: Rejecting the risks of cloud data leaks
