Difference between api manager and runtime manager? in MuleSoft40

 Difference between api manager and runtime manager? in MuleSoft

Both API Manager and Runtime Manager are crucial tools in the MuleSoft 4 platform, but they serve distinct purposes within the API lifecycle. Here's a breakdown of their key differences:

API Manager:

  • Focus: API design, governance, and publication.

  • Activities:

  • Define and document APIs using OpenAPI, RAML, or AsyncAPI specifications.

  • Set access control policies and security measures.

  • Publish APIs to private or public marketplaces.

  • Monitor API usage and performance.

  • Analyze API traffic and generate reports.

Runtime Manager:

  • Focus: Deploying, managing, and monitoring Mule applications and APIs.

  • Activities:

  • Deploy Mule applications and API implementations to various environments (cloud, on-premises).

  • Manage server groups and clusters.

  • Monitor application and infrastructure health.

  • Apply updates and patches.

  • Configure and trigger deployments.

Key Differences:


API Manager

Runtime Manager

Primary purpose

Design, govern, publish APIs

Deploy, manage, monitor applications & APIs


API lifecycle management

Runtime operations & administration

Key functionalities

API design, documentation, security, analytics

Deployment, monitoring, management, configuration


API consumers, developers

Operations teams, application owners


  • API Manager and Runtime Manager work together seamlessly.

  • APIs defined in API Manager are automatically discovered and registered in Runtime Manager for deployment.

  • Runtime Manager provides real-time performance data for APIs, which can be fed back into API Manager for analytics and governance.

Choosing the right Tool:

  • API Manager: Ideal for developers and API owners responsible for API creation, publication, and lifecycle management.

  • Runtime Manager: Designed for operations teams and application owners tasked with deploying, monitoring, and managing Mule applications and APIs in various environments.

Additional Resources:

I hope this explanation clarifies the distinct roles and functionalities of API Manager and Runtime Manager in MuleSoft 4. Feel free to ask if you have any further questions about specific use cases or how these tools interact within your MuleSoft environment.
