The Linux Foundation (LF) Core Infrastructure Initiative (CII) Best Practices badge is a way for Free/Libre and Open Source Software (FLOSS) projects to show that they follow best practices. Projects can voluntarily self-certify, at no cost, by using this web application to explain how they follow each best practice. The CII Best Practices Badge is inspired by the many badges available to projects on GitHub. Consumers of the badge will be able to quickly assess which FLOSS projects are following best practices and as a result are more likely to produce higher-quality secure software.
More information on the CII Best Practices Badging program, including background and criteria, is available on GitHub. Project statistics and criteria statistics are available. The projects page shows participating projects and supports queries (e.g., you can see projects that have a passing badge). You can also see an example (where we try to get our own badge).
