See Spec Hub in action

In this brief demo, see how Spec Hub streamlines spec design, testing, and documentation in Postman—no tool-switching required.

Unify API design

  • Achieve seamless interoperability and scalability with multi-protocol support for OpenAPI and AsyncAPI, with more on the way.
  • Transition effortlessly from design to testing and documentation within Postman, eliminating the need for manual exports or tool-switching.
  • Accelerate the creation of API specifications with auto-completion and real-time error detection.

Generate & sync to collections

  • Convert finalized specs into Postman Collections with a single click to eliminate copy-pasting and manual test script creation.
  • Sync updates to ensure docs, tests, and examples stay up to date—closing the loop between design and runtime.
  • Generate multiple collections from a single specification to support diverse use cases like testing, documentation, and mocking—ensuring consistency across your workflow.

Integrated Governance & Compliance

  • Design and maintain API specifications with built-in validation, linting, and governance rules to ensure compliance with industry standards.
  • Leverage automated linting and governance policies, with built-in Spectral support, to catch errors before they impact production.
  • Apply role-based access controls to ensure API specifications can only be modified and managed by authorized users.

Enhance collaboration & team efficiency

  • Ensure teams stay efficient and in sync with documentation that is automatically updated with the latest API specifications.
  • Enable API collaboration by allowing teams to edit and review API specs in one place for faster, more efficient API development.
  • Streamline communication across teams with shared access and real-time updates to keep everyone aligned.

Create API specification
“Managing API specifications across multiple tools has always been a challenge for our teams. Spec Hub allows us to consolidate our entire API workflow, from design to testing and documentation, into a single, seamless platform. This eliminates the need for constant imports and exports, keeping our teams in sync and accelerating our API development process.”
