How do open-sourced project maintainers separate their code to get community contributions but also develop premium features for paid users?

This page summarizes the projects mentioned and recommended in the original post on

Our great sponsors
  • SonarQube - Static code analysis for 29 languages.
  • Scout APM - Truly a developer’s best friend
  • - Download’s Tech Salary Report
  • Strapi

    🚀 Strapi is the leading open-source headless CMS. It’s 100% JavaScript, fully customizable and developer-first.

    Strapi - They do a mixed-repo but do it quite well. From my quick test, I could delete the single non-open ee folder and the project still worked without it.

  • gitlab

    GitLab gets community contributions. All work, including community contributions, are provided to the main mixed repo. The readonly mirror is then a copy of this with the non-open parts stripped out. The mirror is not used for development at all, it's just a convenience for people that want the project code without the enterprise/proprietary content.

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • gitlab-foss

    GitLab - Again a mixed repo but they also provide a mirror with all non-OS code removed.
