Permit.io
Auth & Security
Permissions and access control as a service
Permit.io is an open-source permissions and access control service that enables developers to implement authorization (auth-z) into applications without extensive security expertise. Built on OPA (Open Policy Agent) and OPAL (Open Policy Administration Layer), the platform treats authorization policies as code, allowing teams to define, manage, and enforce access control rules programmatically. The service is designed for developers and engineering teams who need to add granular permission management to their applications quickly. Rather than building access control systems from scratch, Permit.io provides pre-built infrastructure and tooling that can be integrated in minutes. The platform supports various authentication scenarios and allows policies to be versioned, tested, and deployed alongside application code. Permit.io offers both open-source components and commercial options, making it accessible to projects of different scales. The GitHub repository includes the Permit CLI, enabling command-line interaction with the service for policy management and administration tasks. The product is particularly useful for teams building multi-tenant applications, role-based access control systems, or any application requiring flexible, auditable permission management. By abstracting authorization logic into a dedicated service, Permit.io helps reduce security vulnerabilities while maintaining policy flexibility as application requirements evolve.
