In their own words

PactFlow

PactFlow is a managed Pact Broker for teams checking integrations in distributed systems through contract testing. It supports consumer-driven testing with Pact and bi-directional testing with OpenAPI. Its AI-augmented testing can generate tests from OpenAPI, traffic data or existing code. Integrations include SwaggerHub Editor and Pact plugins, including gRPC and protobuf; pull-request status checks work with GitHub, GitLab, Bitbucket or other source control tools. A Developer API, CLI tools and Terraform support help automate configuration. PactFlow offers a managed service and an Enterprise on-premises option. Starter is free, allows unlimited users and includes two integrations. Team includes 50 integrations and community support; it costs $115.42 a month with yearly billing, billed yearly as $1,385, or $127 a month with monthly billing. Enterprise includes unlimited integrations, SAML SSO, role-based access management and dedicated support, with price available through sales. PactFlow states customer data and backups are stored in AWS data centres in Sydney, Australia, with encryption at rest and in transit.

TypeSpec

TypeSpec is a language for defining API shapes and data models, then producing schemas, API specifications, code, and documentation. Its standard library supports OpenAPI 3.0, JSON Schema 2020-12, and Protobuf. OpenAPI output can feed tools for API gateways, code generation, and validation; JSON Schema output can be used to validate data built from shared models. The HTTP library’s `@useAuth` decorator lets authors attach documented security schemes—including HTTP authentication, API keys, OAuth2, and OpenID Connect—to services, interfaces, or operations. Editor support for Visual Studio Code and Visual Studio includes syntax help and completion; the VS Code extension adds diagnostics, formatting, quick fixes, refactoring, and documentation preview. Users can extend TypeSpec with emitters and decorators. The CLI is available through npm for Node.js or as an experimental standalone executable, and a browser playground is available. TypeSpec is open source and free: free. Its emitter framework is experimental, and client emitters for JavaScript, Python, Java, and C# are in preview.
