We're excited to introduce LeanSpec - a lightweight, flexible Spec-Driven Development (SDD) methodology designed for modern AI-powered development.

What is LeanSpec?​

LeanSpec is built on the principle that AI coding agents need clear context without overwhelming documentation. Traditional SDD approaches either lack the detail AI needs or create so much overhead that nobody maintains them.

Key Features​

  • 🎯 Write only what matters - Clear intent AI can act on
  • 🤖 AI-native from day one - Works with Cursor, GitHub Copilot, Aider, and custom agents
  • 📈 Scale naturally - Solo dev → Small team → Enterprise
  • 🔧 Built-in workflow support - Boards, timelines, dependency tracking
  • 🎨 Your structure - Custom fields, flexible templates

Getting Started​

Check out our Getting Started guide to begin using LeanSpec in your projects.

What's Next?​

We're continuously improving LeanSpec based on real-world usage. Stay tuned for more updates!
