What is Reqvire?
Reqvire is a lightweight, Git-native Requirements-as-Context framework that turns specifications into structured, AI-ready context: enabling smarter development, traceability, and consistent change management.
It unifies system modeling, requirements management, context engineering and AI-assisted development into a single workflow—providing complete traceability, intelligent automation, and faster delivery while staying fully aligned with your codebase.

Key Features
Requirements-as-Context
Create a structured, canonical source of truth for your project.
Reqvire provides a consistent context layer that AI tools can reliably query—so they always understand what needs to be built, where changes belong, and how system components fit together.
Requirements-as-Code
Evolve requirements from static documents into version-controlled, executable artifacts.
Reqvire keeps your system model alive in Git—no more lost specs, outdated docs, or knowledge locked in transient tickets.
Intelligent Engineering
Bring Model-Based Systems Engineering (MBSE) directly into your Git workflow:
-
Specification-Driven Development
Develop from requirements. Enforce clear specifications and generate code that stays tied to its originating requirements. -
Automated Traceability
Maintain instant, bidirectional links between requirements, code, tests, and artifacts. -
Verification & Validation
Track verifications, ensure coverage, and validate that implementations meet intended behavior. -
Smart Change Propagation
Identify impacted parts of the system and help propagate requirement changes consistently across the model and codebase. -
Seamless Integration
Works naturally with branches, pull requests, reviews, and CI/CD. No workflow disruption—just added intelligence.
