Design REST, event-driven, GraphQL, gRPC, and Smithy APIs in one place.

### All-in-one specification editor

Edit specs with visual outlines or code views using familiar Postman workflows.

### Built-in validation and governance

Set up governance rules, have a real-time view into API compliance with API Catalog, and automatically enforce standards with Postman CLI.

## Design APIs faster with AI that knows your standards

Postman AI generates spec scaffolds, applies your governance rules, and writes endpoint descriptions so your team goes from just getting started to compliant API spec in minutes.

*CAPABILITIES*

### Define and manage API specs on the platform your teams already use

Spec Hub enables teams to seamlessly bring API design and governance workflows into Postman.

### Unify API design across teams and workflows

Design APIs once using standards-based specifications that serve as a shared foundation across teams.

### Activate specs across the API lifecycle

Generate and sync collections automatically to keep specifications and Postman collections aligned as APIs evolve. No more manual updates or copy and paste needed.

### Ensure APIs are in compliance

Define and enforce API standards with custom governance rules applied directly to API specifications.

### Governance Reports

Immediately see where API specifications fall out of compliance across teams and services.

### Live documentation

Visualize changes as you work with live documentation previews that update as you edit your OpenAPI or Async API spec.

### Role-based access controls

Control who can create, edit, and approve API specifications.

> 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.
