Pact

Consumer-driven contract testing for microservices

About Pact

A code-first tool for testing integrations using consumer-driven contracts, ensuring services can communicate without end-to-end tests by verifying expectations between consumers and providers in CI pipelines. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
