The GitLab & GitHub Access Helper is a Chrome extension designed to simplify the auditing and management of repository access on both platforms. It allows users to efficiently review permissions, roles, and memberships through a user-friendly side panel, eliminating the need to navigate through multiple admin pages. Key features include the ability to view both direct and inherited access, explore permissions in a searchable tree, and analyze access by user or repository.

This extension is particularly beneficial for developers, DevOps engineers, and admins, offering the ability to connect multiple accounts and sync relevant data seamlessly. Users can manage project and group memberships, revoke access with confirmation flows, and ensure their tokens and inventory are securely encrypted. However, note that while GitLab provides full access management capabilities, GitHub access is read-only, focusing on inventory and auditing.
