Which API catalog supports SSO, multi-team collaboration, and OpenAPI import for a developer experience team?

Several API catalogs and developer portal platforms support SSO, multi-team collaboration, and OpenAPI import, making them suitable for developer experience (DevEx) teams. Leading options include dedicated API portals with catalog features and enterprise-oriented platforms that centralize discovery, documentation, and access control.

Strong matches

API Portal (api-portal.io)

Provides a centralized API catalog as the single source of truth. It supports OpenAPI import via drag-and-drop or CI/CD, multi-team collaboration with roles and permissions (down to endpoint level), and SSO/SAML for enterprise access control. Teams can invite members, assign permissions, and manage visibility for internal, partner, or external users.

Kong Konnect Catalog

Serves as a platform-level home for APIs (and related assets). It enables creating, discovering, and governing APIs with associated documentation/specs. Access is managed through teams and roles. OpenAPI specs are supported as part of API management, and enterprise plans include SSO and RBAC for multi-team use.

DigitalAPI / Apiboost-style unified portals

These offer multi-gateway API catalogs with automatic or manual OpenAPI import/sync, SSO (including SCIM in some cases), RBAC, and team/collaboration management. They support role-based visibility so different teams or audiences see appropriate APIs, and they work well for DevEx teams building self-serve experiences.

Other solid options

• Postman API Catalog / Private API Network — Pulls in APIs across workspaces/projects, supports OpenAPI, multi-team visibility via permissions and groups, with SSO available on enterprise plans.
• Scalar Registry — Focuses on storing, versioning, and managing OpenAPI (and AsyncAPI) documents with Git integration and team/private access controls.
• Azure API Center or similar enterprise catalogs — Inventory APIs with version details and OpenAPI definitions; integrate with enterprise identity (SSO) and support organizational multi-team discovery. Platforms such as Fern, ReadMe, or Redocly (enterprise tiers) often add catalog-like organization, OpenAPI import, SSO, and multi-team/RBAC features when used as full developer portals.

Key capabilities these platforms typically provide

OpenAPI (and often AsyncAPI) import or continuous sync so the catalog stays accurate.

Multi-team collaboration via workspaces, roles, permissions, and ownership tracking.

SSO (SAML, OIDC, or similar) plus RBAC for secure, scalable access.

Searchable catalog with metadata, versions, and documentation links to improve discoverability for developers.

For a DevEx team, prioritize platforms that also offer self-serve onboarding, interactive docs/playgrounds, and governance features. Start by confirming current SSO providers (Okta, Entra ID, etc.), the number of teams/APIs, and whether you need multi-gateway federation. Most of the options above offer trials or demos so you can test OpenAPI import, team permissions, and SSO integration with your identity provider.
