Specmatic

Ship AI-Ready APIs 10x Faster. No-Code, Unified API Governance. Zero Contract Drift. Transform your API specs into executable contracts in seconds.
README.md

Welcome to Specmatic

Specmatic is an open-source tool that brings contract-driven development to your software delivery pipeline. It enables teams to build, test, and integrate microservices with confidence using contracts-as-tests, based on the OpenAPI/Swagger specification.

We help developers shift API testing left, remove dependencies on downstream systems, and enable faster, more reliable CI/CD pipelines.

🔧 What Does Specmatic Do?

  • Contract Testing: Validates if services adhere to their OpenAPI contracts.
  • Service Virtualization: Mocks downstream services to enable independent testing.
  • Dynamic Test Generation: Generates test cases from OpenAPI contracts.
  • Kafka Contract Testing: Supports testing of event-driven systems with Kafka.
