Why Create CHAOSS?

The importance of open source software is no longer in question. However, its importance raises important questions about the open source ecosystem. Open source contributors want to know where they should place their efforts and know that they are making an impact. Open source communities want to attract new members, ensure consistent quality, and reward valuable members. Open source companies want to know which communities and software to engage with, communicate the impact the organization has on the community, and evaluate the work of their employees within open source. Open source foundations want to identify and respond to community needs, evaluate the impact of their work, and promote communities.

In response to these issues, the CHAOSS community is developing metrics, methodologies, and software for expressing open source project health and sustainability. By measuring open source project health and sustainability, CHAOSS seeks to improve the transparency and actionability of open source project health and sustainability so that relevant stakeholders can make more informed decisions about open source project engagement.

What are CHAOSS Goals?

The project aims to:

  • Establish standard implementation-agnostic metrics for measuring community activity, contributions, and health

  • Produce integrated open source software for analyzing software community development

  • Build reproducible project health reports/containers

CHAOSS Roadmap

Who are we?

CHAOSS is a Linux Foundation project focused on creating analytics and metrics to help define community health. Work in the CHAOSS Project community is organized in two committees and four working groups:


  • The Metrics Committee works on establishing implementation-agnostic metrics for measuring community activity, contributions, and health.

  • The Software Committee works on producing integrated, open source software for analyzing software development, and definition of standards and models used in that software in specific use cases.

Working Groups

The goal of the working groups is to refine the metrics and to work with software implementations. The working groups are:

Spreading CHAOSS

The CHAOSS project was officially announced at the Open Source Summit North America 2017 in Los Angeles. We thank all participants of the BoF and workshop for participating and contributing. Below is a picture of the workshop participants at OSSNA2017.
