The open source community
for infrastructure software

OW2 is an independent community dedicated to open source industry-grade enterprise computing infrastructure software, including middleware, application platforms and cloud computing technologies.

Make a stand, focus your open source efforts, help steer the community, increase your open source visibility, promote your projects, and join renowned industry leaders, SMEs, academics and individuals.

OW2 hosts some one hundred open source projects spanning application platforms, components, middleware, cloudware and tools for the development, deployment and management of distributed and cloud applications.

At OW2 it usually starts with an open source project. We provide resources, governance and help build awareness for your project. Checkout the project life cycle and fill in the submission form. Join the code base.

Enhance the quality and facilitate the market adoption of your project with the unique suite of tools freely accessible through Software Quality Assurance and Trustworthiness (SQuAT) the OW2 quality program.

The beta version of OW2 marketplace is made available through EU-funded project AppHub. Stay tuned for future development and full opening of the marketplace to OW2 projects in 2016.

Leveraging open source to foster collaborative innovation is a powerful strategy. OW2 is the Open Source Software community for collaborative R&D projects. We provides community support and dissemination services to multinational open source collaborative projects. OW2 provides dissemination and community building services to large collaborative R&D projects. In particular, OW2 has established itself as the reference dissemination and community platform for complex government-supported, open source-oriented projects
