Definition
WSO2 API Manager is an open-source, full lifecycle API management platform for designing, publishing, securing, and analyzing APIs, developed by WSO2.
Overview
WSO2 API Manager covers the same broad API lifecycle territory as commercial platforms like Apigee, but as an open-source product that organizations can self-host to retain full control over their infrastructure and data. It includes a gateway component that enforces security and traffic policies, a developer portal for publishing APIs to internal or external consumers, a publisher interface for API teams to design and version APIs, and analytics for monitoring usage and performance. It supports common API security standards including OAuth 2.0 and OpenID Connect, along with rate limiting, throttling policies, and mediation logic for transforming requests and responses between clients and backend services. WSO2 also offers this capability as part of a broader integration platform (WSO2's identity server, integration server, and streaming/analytics products), so API Manager is often deployed alongside other WSO2 components in larger enterprise architectures. Because it is fully open source and self-hostable, WSO2 API Manager is frequently chosen by organizations — including government, financial services, and telecom — that want enterprise-grade API management without recurring per-call licensing tied to a specific cloud vendor.
