Turn your contracts into executable specifications. Contract Driven Development - Collaboratively Design & Independently Deploy MicroServices & MicroFrontends.

Lightweight implementation of contract checking in C++ and helpers for unit testing contracts without the need for death tests.

This project demonstrates contract-first development using a spec-kit approach where OpenAPI specifications evolve organically through feature development. Each feature analyzes existing contracts for reuse before extending the API, using Specmatic MCP as intelligent guardrails throughout the process.
