Summary

Pact Broker shares consumer-driven contracts and verification results, primarily for Pact contracts, while also accepting contracts that can be represented as JSON. Its compatibility matrix helps teams identify consumer and provider versions that can safely be deployed together. In a typical CI workflow, consumer builds publish pacts, provider builds retrieve and verify them, and consumers can use the can-i-deploy command before a release. Features include a REST API, embedded API browser, generated pact documentation, service network diagrams, verification results, and status badges. Webhooks can trigger actions when contracts change, such as starting a provider build or notifying a Slack channel. Deployment documentation covers Docker, Terraform on AWS, PostgreSQL, and SQLite for quick-start and CI use; SQLite is not supported for long-term broker operation. Docker images support linux/amd64 and linux/arm64. The open-source self-hosted broker is free, but users handle hosting, operation, security, maintenance, and upgrades. PactFlow also lists free and paid plans, including Team options at $115.42 per month billed yearly or $127.00 per month.
