Turn OpenAPI and AsyncAPI specs into executable contracts and smart mocks.
Specmatic treats your API specification as the single source of truth: it verifies that a provider implements the spec, generates a mock that conforms to it for consumers, and fails the build when either side drifts. Unlike consumer-driven contract testing it requires no coordination ritual between teams — the spec is the contract.
