We believe good open source tools are important when using open source software.

At nexB, we have been creating, contributing to and using free and open source software from the start. We contribute back to projects that we use, and we sponsor our own open source projects for software provenance analysis (ScanCode) and open source attribution compliance (AboutCode). We believe that good open source tools help you use open source, including compliance with license obligations.

AboutCode logo is a community of open source developers who are trying to make open source easier to use by providing open source tools to discover, identify and track open source components for Software Composition Analysis (SCA).

Software Package Data Exchange (SPDX) specification is a standard format for communicating the components, licenses and copyrights associated with a software package. We are co-founders of this working group from the Linux Foundation.

The aim of SPDX is to reduce redundant work by providing a common format for companies and communities to share information across the supply chain, thereby streamlining and improving compliance.

Google Summer of Code Logo
Google Summer of Code (GSoC) is a program that encourages student developers to work on and learn about open source development. Google sponsors select students to work on open source projects for three months. nexB is excited to work with students who are passionate about open source development and want to help AboutCode build better open source tooling for Software Composition Analysis.

The Linux Foundation is a non-profit consortium dedicated to fostering the growth of Linux. Founded in 2000, The Linux Foundation sponsors the work of Linux creator Linus Torvalds and is supported by leading Linux and open source companies and developers from around the world.

nexB has been a Silver member since 2013. We are a vendor for the Commercial Compliance Tools which is approved by the Linux Foundation.

ClearlyDefined and its parent organization, the Open Source Initiative, are on a mission to help FOSS projects thrive by being, well, clearly defined. Lack of clarity around licenses and security vulnerabilities reduces engagement — that means fewer users, fewer contributors and a smaller community. This is a community-wide challenge that needs a community-wide approach.
