SpringSource

SpringSource was the software company behind the open-source Spring Framework for Java. Founded in 2004 as Interface21 by Rod Johnson and colleagues, it was venture-backed (Accel, Benchmark) and acquired by VMware in 2009. The Spring portfolio subsequently moved through Pivotal and VMware Tanzu and is maintained today by Broadcom. The springsource.com domain now 301-redirects to spring.io, the current home of the Spring ecosystem. SpringSource exposed no standalone public API of its own; this profile documents the historical company and its lineage into today's Spring projects.

SpringSource is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, Java, Spring Framework, and Open Source.
