Transform your GraphQL API specs into executable contracts in seconds

Now you can easily leverage your GraphQL APIs for contract testing, intelligent service virtualisation and backward compatibility testing, just like you would for your OpenAPI-based services. No more complex and brittle setups that involve an assortment of tools – Specmatic handles it all for you, thereby making for a one stop solution that enables a seamless DevEx.

Getting Started

For GraphQL, the setup process is just as straightforward as it is for OpenAPI. All you need are your GraphQL schema files, along with a simple Specmatic configuration, and you’re good to go!
