AWS deployment

The `signet deploy` command provisions an ECS Fargate cluster and deploys the broker and supporting infrastructure to AWS.Read 7 Oct 2026 · signet-framework.dev

AWS requirements

The AWS deploy command requires the AWS CLI and a logged-in default profile with AdministratorAccess.Read 7 Oct 2026 · signet-framework.dev

Broker

The Signet Broker manages contracts and provides a web interface for exploring test results.Read 7 Oct 2026 · signet-framework.dev

CI/CD

The CLI and broker webhooks support automating contract testing and deployment gates in CI/CD pipelines.Read 7 Oct 2026 · signet-framework.dev

Consumer testing

The CLI can record existing service tests to generate consumer contracts, avoiding the need to write new tests for adoption.Read 7 Oct 2026 · signet-framework.dev

Contract formats

Signet uses OpenAPI specifications for providers and Pact-format consumer contracts.Read 7 Oct 2026 · signet-framework.dev

Contract generation

The CLI proxy records requests and responses during tests and generates a consumer contract.Read 7 Oct 2026 · signet-framework.dev

Deployment checks

Deploy Guard tracks deployments by environment and checks compatibility and provider availability before a service deploys.Read 7 Oct 2026 · signet-framework.dev

Deployment safety

Deploy Guard checks service compatibility and dependency deployment status before a service is deployed to an environment.Read 7 Oct 2026 · signet-framework.dev

Hosting

The broker can be self-hosted on AWS with the deploy command or started using the provided Docker Compose file.Read 7 Oct 2026 · signet-framework.dev

Installation

The CLI installs through npm, and the proxy and test commands require Node.js runtime support.Read 7 Oct 2026 · signet-framework.dev

Managed hosting

Signet does not provide a managed option for deployment, scaling, or high availability.Read 7 Oct 2026 · signet-framework.dev

Notable limit

Signet requires a separate consumer contract for each consumer-provider integration and one provider specification per provider.Read 7 Oct 2026 · signet-framework.dev

OpenAPI contracts

An OpenAPI spec is the authoritative contract that consumer and provider services are expected to follow.Read 7 Oct 2026 · signet-framework.dev

Other hosting

For other cloud providers or on-premises hosting, Signet provides a Docker Compose deployment option.Read 7 Oct 2026 · signet-framework.dev

Provider verification

Signet can generate tests from the API spec and run them against the provider service.Read 7 Oct 2026 · signet-framework.dev

Web interface

The Signet Broker has a web interface for managing contracts and exploring test results.Read 7 Oct 2026 · signet-framework.dev
