A GitHub App that continuously monitors and enforces security policies across organizations and repositories.
Allstar is a GitHub App that automates security policy enforcement for GitHub organizations and repositories. It continuously monitors for violations of security best practices—such as missing branch protection or SECURITY.md files—and can alert maintainers via issues or automatically revert settings to a secure state. It helps maintain consistent security postures across many projects with minimal manual intervention.
Organization administrators and repository maintainers who need to enforce security policies across multiple GitHub repositories, especially in open-source or large-scale development environments.
Developers choose Allstar for its deep integration with GitHub, flexible policy configuration, and ability to automate both detection and remediation of security misconfigurations, reducing manual oversight while improving compliance.
GitHub App to set and enforce security policies
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports both Opt-In and Opt-Out strategies at the organization level with granular control over repositories, as detailed in the Org-Level Options table, allowing tailored adoption.
Can automatically fix settings like branch protection when violations are detected, reducing manual intervention for common security misconfigurations, as shown in the Policies section.
Includes built-in policies (e.g., dangerous workflow detection) and allows contribution of new ones, enabling customization to fit specific security needs, per the README.
Can be deployed as a GitHub Action or service daemon for organizations with compliance needs, though the README warns it requires high effort and maintenance.
Several proposed actions like block, email, and rpc are not yet implemented, limiting enforcement options compared to what's planned in the Actions section.
Self-hosting is described as 'very high' effort with warnings like 'Only self-host if you must!', requiring configuration, securing, and ongoing maintenance.
Exclusively designed for GitHub, making it unsuitable for organizations using other version control systems, with no support for GitLab or Bitbucket.
