Project Title
OpenSpec — Spec-driven development for AI coding assistants
Overview
OpenSpec is a TypeScript-based project that enables specification-driven development for AI coding assistants. It aligns human and AI stakeholders by locking intent before implementation, ensuring deterministic and reviewable outputs. OpenSpec stands out for its lightweight workflow, brownfield-first approach, and change tracking capabilities.
Key Features
- Lightweight specification workflow with no API keys required
- Brownfield-first approach, separating source of truth from proposals
- Change tracking for proposals, tasks, and spec updates
- Works with existing AI tools, including custom slash commands and context rules
Use Cases
- Use case 1: Software development teams looking to align on specs before coding to ensure deterministic outputs
- Use case 2: Organizations needing structured change management for proposals, tasks, and spec updates
- Use case 3: AI tool users who want to integrate spec-driven development into their existing workflows
Advantages
- Advantage 1: Simplifies the collaboration between humans and AI coding assistants
- Advantage 2: Provides shared visibility into what's proposed, active, or archived
- Advantage 3: Supports modification of existing behavior (1→n), not just new features (0→1)
Limitations / Considerations
- Limitation 1: As a relatively new project, it may lack some features or have a smaller community compared to more established alternatives
- Limitation 2: The effectiveness of OpenSpec depends on the adoption and integration of its workflow by the development team
Similar / Related Projects
- Spec-kit: Focuses on brand-new features (0→1), while OpenSpec also excels in modifying existing behavior (1→n)
- Kiro: Another tool for new features (0→1), OpenSpec differentiates by its brownfield-first approach and change tracking
