What is WSO2 API Manager?

WSO2 API Manager is an open source, full lifecycle API management platform for designing, publishing, securing, and analyzing REST, SOAP, GraphQL, and event driven APIs. It bundles a publisher console, developer portal, API gateway, key manager, and analytics engine into a single deployment, and can run self-hosted, in the cloud, or hybrid with no per-gateway fees since the core platform is Apache licensed open source.

Paid options include a 30 day trial and a self-serve Pay-As-You-Go plan starting at $119 per month for up to 10 managed interfaces and 10 million gateway events, billed monthly with volume discounts. Enterprise plans add private data planes, federation, extra developer portals, and 24x7 support on a custom, sales-negotiated basis.
