The record

Purpose: Pact Broker shares consumer-driven contracts and verification results, and is optimized for Pact contracts while also accepting contracts serializable to JSON.
Safe deployments: It provides a compatibility matrix to identify consumer and provider versions that can safely be deployed together.
Core features: Features include a REST API, embedded API browser, autogenerated pact documentation, service network diagrams, verification results, and status badges.
Automation: Webhooks can trigger actions when pacts change, such as running a provider build or notifying a Slack channel.
CI workflow: Consumer builds publish pacts, provider builds retrieve and verify them, and consumers can use the can-i-deploy command to check before deployment.
Integrations: The project documents Docker deployment, Terraform on AWS, PostgreSQL, and SQLite for quick-start and CI use; SQLite is not supported for long-term broker operation.
API availability: The Pact Broker exposes a RESTful API for publishing and retrieving pacts.
Authentication: The Docker distribution supports configurable basic-auth users with read/write and read-only privileges.
Security scanning: The Docker project says it uses bundler-audit, Trivy scans on published image digests and weekly, and Renovate.
Supported platforms: The Docker project provides multi-platform images for linux/amd64 and linux/arm64.
Support: The project directs users to its wiki, GitHub issues, Stack Overflow with the pact-broker tag, and Pact Slack.
License: The Pact Broker repository is published under the MIT license.
Free trial: PactFlow's Team plan offers a free 14-day trial, and its Starter plan is listed as free.
Headquarters: Melbourne, Australia
Price from: $115.42/mo
