Ensures human-AI alignment on project requirements before coding.
Provides a streamlined artifact-guided workflow (propose, apply, archive).
Supports iterative development for projects of all scales, from personal to enterprise.
Integrates with over 25 development tools and supports multi-language projects.
Quick Start
npm install -g @fission-ai/openspec@latest && cd your-project && openspec initDetailed Introduction
AI coding assistants are powerful but can be unpredictable when requirements are confined to chat history. OpenSpec addresses this by introducing a lightweight specification layer, ensuring human and AI alignment on 'what to build' before any code is written. It champions a fluid, iterative, and user-friendly development approach, applicable to both existing ('brownfield') and new ('greenfield') projects. By establishing clear, agreed-upon specifications, OpenSpec makes AI-assisted development more predictable, manageable, and scalable for any project size.
