WSO2 API Manager

WSO2 API Manager provides you with a unified platform to manage the entire API lifecycle, from design and publishing to monetization and retirement. You can create high-quality APIs by importing definitions or using the intuitive designer, then secure them with robust OAuth2, OIDC, and tiered throttling policies. It helps you bridge the gap between your backend services and the developers who need them, whether they are internal teams or external partners.

You can deploy the platform anywhere—on-premises, in a private cloud, or as a fully managed service. It includes a customizable developer portal that lets your users discover, test, and subscribe to APIs easily. By providing deep insights through integrated analytics, the software allows you to track usage patterns, monitor performance, and identify potential issues before they impact your users.
