Contract-driven development with Specmatic unifies API specifications (OpenAPI, AsyncAPI, GraphQL, gRPC) into a single executable contract that both consumer and provider teams validate against. Consumer teams run Specmatic as a smart stub to code and test integrations, while provider teams execute contract tests against the real service in CI. Both sides must pass verification gates before deployment, preventing breaking changes and ensuring API compatibility across teams. Fork this diagram on Diagrams.so to customize the workflow for your organization's API governance and CI/CD pipeline. This pattern eliminates integration surprises by catching contract violations early, reducing deployment risk and coordination overhead.
