Cerbos vs OPAL (Permit.io)
Cerbos and OPAL (Permit.io) are both open source software projects that provide authorization solutions, but they have different functionalities and features. Here's a detailed comparison of the two projects: Purpose: Cerbos is an open source policy engine that allows you to define and enforce fine-grained access control policies for your applications. It is designed to be easily integrated into your existing systems and can work with multiple programming languages. OPAL (Permit.io), on the other hand, is an open source permission management system that allows you to define and manage permissions across multiple services and applications. Technologies used: Cerbos is written in Go and uses a simple domain-specific language to define policies. It can work with multiple programming languages, including Java, Python, and Node.js. OPAL (Permit.io) is built using TypeScript and provides a web-based user interface for managing permissions. Features: Cerbos provides a flexible and expressive way to define access control policies based on a variety of factors, such as user roles, resource attributes, and actions. It also allows you to test policies before deploying them and provides detailed audit logging for access control decisions. OPAL (Permit.io) allows you to define and manage permissions across multiple services and applications, and provides a web-based user interface for managing permissions. It also allows you to define permissions based on attributes and conditions. Community support: Both Cerbos and OPAL (Permit.io) are open source software projects and have active communities of contributors and users. Cerbos has a relatively small community compared to OPAL (Permit.io), which has a larger and more active community of contributors and users. OPAL (Permit.io) also provides comprehensive documentation and support for its APIs, making it easier for developers to integrate permission management functionalities into their applications. In summary, while both Cerbos and OPAL (Permit.io) are open source software projects that provide authorization solutions, they have different purposes, functionalities, and features. Cerbos is a policy engine for access control, while OPAL (Permit.io) is a permission management system that allows you to define and manage permissions across multiple services and applications. The technologies used, features provided, and community support also differ between the two projects.
