Yes. Many organisations start at one level and upgrade as their involvement grows. No. While many members actively contribute to projects, membership is open to organisations that want to collaborate, influence, and support the ecosystem in different ways. The Eclipse Foundation
Member Portal
gives your organisation visibility into its participation across the ecosystem. Track your involvement in projects and industry collaborations, and access resources and tools designed to support your engagement. No, but many members choose to participate in working groups to collaborate more closely on specific technologies and industry initiatives. Eclipse Foundation AISBL is the Foundation’s European-based legal entity. Most new members join through AISBL, which offers the same benefits as the original U.S.-based organisation. Eclipse Foundation Industry Collaborations are part of the Foundation’s broader ecosystem and operate within its membership and governance framework. Organisations must first become Eclipse Foundation members before joining a Working Group or an Interest Group. This ensures that every participant benefits from the same legal, intellectual property, governance, and community framework, creating a trusted, vendor-neutral environment for collaboration.
